When planning for an Isilon OneFS upgrade, there are many documents you can reference. We recently conducted research to learn how these documents help EMC Isilon customers and employees through the OneFS upgrade process. Based on our findings, we made some changes to Isilon OneFS upgrade content that we want to share with you.

OneFS Upgrade Info Hub

To help you find OneFS upgrade documents more quickly, please visit the new OneFS UpgradesInfo Hub. An info hub is a web page on the Isilon Community that serves as a nexus of useful content related to a specific topic. The OneFS Upgrades – Info Hub will be refreshed frequently with new and relevant information, so check this web page often.

OneFS upgrade readiness checklist archive

The content from OneFS Upgrade Readiness Checklists (from OneFS 6.5 through OneFS 7.2 versions) have been merged with the Upgrade Planning and Process Guide. If you bookmarked a link to a OneFS Upgrade Readiness Checklist in the past, you’ll now be redirected to this message.

OneFS Upgrade Readiness Checklist Archive

Our main goal is to reduce the number of documents you need to refer to when planning for a OneFS upgrade. By merging these checklists with the definitive Upgrade Planning and Process Guide, we’re creating a single reference to help you through the entire OneFS upgrade process.

The Upgrade Planning and Process Guide can be applied to any version of OneFS. Because this is a long document, we’ll be incorporating changes over time to help make it easier to navigate. For example, we’ll include a checklist at the beginning of the guide, which is linked to corresponding sections for more information.

Top 3 operational differences in EMC Isilon OneFS 7.1.1

As EMC Isilon OneFS 6.5 and OneFS 7.0 reach their end-of-service life (EOSL) this year, many EMC Isilon customers will be upgrading to OneFS 7.1.1. If you plan to upgrade to OneFS 7.1.1, there are several new features, enhancements, and operational changes that may affect your day-to-day administration tasks. We want you to be aware of some the differences that impact upgrade planning, because they may require pre-upgrade tasks. You can find detailed information in the OneFS 7.1.1 Behavioral and Operational Differences and New Features document on the Isilon Community and OneFS 7.1.1 release notes on the EMC Online Support site.

Meanwhile, here are the top three changes for you to prepare for:

  • Access zones: directory configuration and NFS access
  • SmartPools®: node pool configuration
  • Role-based access controls

Access zones

In OneFS 6.5, access to cluster resources was controlled by authentication providers such as SMB, NFS, and SSH. Beginning in OneFS 7.0, user access to the cluster is controlled through access zones. With access zones, you can partition the cluster configuration into self-contained units, and configure a subset of parameters as a virtual cluster with its own set of authentication providers, user mapping rules, and SMB shares. The built-in access zone is the System zone, which, by default provides the same behavior as OneFS 6.5. You can connect to access zones using all available authentication providers, NFS exports, and SMB shares.

In OneFS 7.1.1, however, you cannot configure NFS exports in multiple access zones. NFS access is restricted to the System zone only. (In OneFS 7.2, NFS is zone-aware for access to multiple access zones.)

Also, access zones require a unique top-level root directory in OneFS 7.1.1. The root directories, or base paths, for multiple access zones in OneFS 7.1.1 cannot overlap with each other.

An important note!

If you currently use multiple access zones in your OneFS 7.0 or OneFS 7.1 cluster, you must check your access zone configuration for overlapping directories. If base paths overlap before you upgrade to OneFS 7.1.1, all previously created access zones will be assigned a base path of /ifs. Refer to OneFS 7.1.1 and Later: Best Practices for Upgrading Clusters Configured with Access Zones before upgrading to prevent a scenario where directories are assigned a new base path to accommodate access zones in OneFS 7.1.1.

SmartPools

In OneFS 6.5, a group of nodes is called a disk pool. Different types of drives could be assigned to a disk pool. There are several changes in SmartPools since 7.0. Beginning in OneFS 7.0, a group of nodes is called a node pool, and a group of disks in a node pool is called a disk pool. Also beginning in OneFS 7.0, nodes are automatically assigned to node pools in the cluster based on the node type. This is called autoprovisioning. Node pools can only include drives of the same equivalence class (review the equivalence class of nodes in the Isilon Supportability & Compatibility Guide). However, you can include multiple node pools into a higher level grouping called tiers. Finally, in the web administration interface of OneFS 7.1.1, SmartPools is located as a tab within Storage Pools.

Disk pools can no longer be viewed or targeted directly through the OneFS 7.1.1 web administration interface or the command-line interface. Instead, the smallest unit of storage that can be administered in OneFS 7.0 is a node pool. Disk pools are managed exclusively by the system through autoprovisioning.

An important note!

If you are running OneFS 6.5 or OneFS 6.5.5 and have node pools of mixed node types, you must configure disk pools into supported OneFS 7.0 and later node pool configurations well in advance of upgrading to OneFS 7.1.1. Supported node pool configurations must contain nodes of the same type, according to their node equivalence class.

Role-based access control (RBAC)

In OneFS 6.5, you can grant web and SSH login and configuration access to non-root users by adding them to the administrator group. In OneFS 7.0 and later, the admin group is replaced with the administrator role using role-based access control (RBAC). RBAC enables you to create and configure additional roles. A role is a collection of OneFS privileges that are granted to members of that role as they log in to the cluster. Only root and admin user accounts can perform administrative tasks and add members to roles. OneFS comes pre-loaded with built-in roles for security, auditing, and system administration, and you can create custom roles with their own sets of privileges.

For information about role-based access, including a description of roles and privileges, see Isilon OneFS 7.0: Role-Based Access Control.

An important note!

For OneFS 6.5 and OneFS 6.5.5 users upgrading to OneFS 7.1.1, make sure you add existing administrators to an administrator role.

All about EMC Isilon OneFS release notes

Latest posts by Deb Kuykendall (see all)

As you prepare to upgrade your EMC Isilon cluster to a new version of OneFS, you probably want to know the following information:

  • What new features are in the release
  • Which issues are fixed
  • Whether any issues involved with the new release could affect you

All this information can be found in the OneFS release notes. The release notes serve as the primary source for information about fixed issues, new features, enhancements, previously released patches, and known issues that affect the release.

How to find release notes

Currently, two sets of release notes are published for each supported OneFS branch. The initial release note is published when a new major or minor OneFS release is released (for example, 7.0, 7.1.1, and 7.2.0). Subsequently, new maintenance release (MR) notes are published whenever a new maintenance version for a particular branch is released (for example, 7.0.2.12, 7.1.1.2, and 7.2.0.1). The initial and maintenance release notes contain similar information, but there are a few differences.

All OneFS release notes are available in PDF format from the EMC Online Support site. The easiest way to find them is to go to support.emc.com and search for “OneFS <your 3-digit release number> release notes.” For example, if you’re running 7.0.2.12, search for “OneFS 7.0.2 release notes.”  You’ll find both the initial OneFS 7.0.2 Release Notes and the OneFS 7.0.2 MR Release Notes.

Searching for OneFS 7.0.2 release notes on the EMC Online Support site.

Searching for OneFS 7.0.2 release notes on the EMC Online Support site.

For more information about OneFS major, minor, and maintenance releases, see knowledgebase article 89210 on the EMC Online Support site.

What you’ll find in release notes

Release notes contain summary descriptions of issues that are fixed in the release, and known issues that affect the release. But it’s important to note that these lists aren’t all inclusive. We provide information about fixed and known issues that Isilon customers have reported or might encounter. Some fixes and known issues that affect OneFS code under-the-hood, and don’t have a known customer impact, aren’t included in the release notes.

The initial release notes contain information about functionality changes between the previous major/minor OneFS release and the current one—for example, changes in the formatting of CLI commands. They also contain summaries of new features. The MR release notes don’t contain feature and functionality information, but do contain information about previously released patches that are included in the release. In most cases, the initial release notes don’t contain any information about patches.

Structure and content

Initial and MR release notes contain a standard set of topics, as you’ll see in this screen shot from the 7.1.1.2 maintenance release notes.

7-1-1-2 toc_v2The Upgrading OneFS topic contains information about where you can find system requirements and applicable patches for the release, as well as the list of OneFS releases that can be upgraded to the documented release.

The release note also contains tables listing enhancements that were added in the release—for example, new command options—and issues that were resolved (that is, bug fixes). In maintenance release notes, the Enhancements and Resolved issues topics are cumulative and organized by maintenance release number.

The patches topic, which is relatively new to the release notes template, contains a table listing previously released patches that were included in the current maintenance release or a preceding maintenance release.

Improvements over time

Over the past few years, changes have been made to improve the ease of use and overall quality of the release notes. For example, because MR release notes are cumulative, they can become quite long. To fix this, we removed some information that can be accessed in other product documents, such as the upgrade instructions.

We also responded to requests to add patch and hardware compatibility information. For example, information about previously released patches can help you to confirm whether or not a later release includes the fixes from a patch that you’ve installed on your cluster.

Finally, we understand that cross-referencing two different types of release notes can be challenging, and that it might not always be clear which document contains the information you need. Looking ahead, we plan to combine the initial and MR release notes into a single document. This document will contain information about functionality changes and features that were introduced when the major or minor release was made available, but it will also be updated to include information about the most current MR that’s available for download from the EMC Online Support site.

Provide us with your release notes feedback

Do the release notes provide the information that you really need? Does the format help you find the information you’re looking for?  Please take a minute or two to help us improve the release notes so we can learn about ways to better serve your needs.

isilon-onefs-7-0Attention all current EMC® Isilon® OneFS 6.5 users: OneFS 6.5 will reach its end of service life (EOSL) on June 30, 2015. OneFS 7.0 introduces several new features, enhancements, and operational changes. If you need to upgrade to OneFS 7.0, you might be wondering what’s different about this version and how these differences will affect your day-to-day administrative tasks. You can learn more by looking at the Administrative Differences in OneFS 7.0 white paper.

The top three changes that OneFS 6.5 users should prepare for are:

  • Administration using role-based access control (RBAC)
  • Authentication using access zones
  • Managing groups of nodes in SmartPools

Role-based access control

In OneFS 6.5, you can grant web and SSH login and configuration access to non-root users by adding them to the admin group. The admin group is replaced with the administrator role in OneFS 7.0 using RBAC. A role is a collection of OneFS privileges, usually associated with a configuration subsystem, that are granted to members of that role as they log in to the cluster.

For information about role-based access, including a description of roles and privileges, see Isilon OneFS 7.0: Role-Based Access Control.

An important note!

After you upgrade to OneFS 7.0, make sure you add existing administrators to an administrator role.

Access Zones

In OneFS 7.0, all user access to the cluster is controlled through access zones. With access zones, you can partition the cluster configuration into self-contained units and configure a subset of parameters as a virtual cluster with its own set of authentication providers, user mapping rules, and SMB shares. The built-in access zone is the “System” zone, which by default provides the same behavior as OneFS 6.5, using all available authentication providers, NFS exports, and SMB shares.

For information about access zones, see the OneFS 7.0.2 Administration Guide.

SmartPools

In OneFS 6.5, a group of nodes is called a disk pool. In OneFS 7.0, a group of nodes is called a node pool, and a group of disks in a node pool is called a disk pool. Also, Isilon nodes are automatically assigned to node pools in the cluster based on the node type. This is called autoprovisioning. Disk pools can no longer be viewed or targeted directly through the OneFS 7.0 web administration interface or the command-line interface. Instead, the smallest unit of storage that can be administered in OneFS 7.0 is a node pool. Disk pools are managed exclusively by the system through autoprovisioning.

An important note!

Before you upgrade to OneFS 7.0, you must configure disk pools into a supported node pool configuration. Disk pools must contain nodes of the same type, according to their node equivalence class. Disk pools that contain a mixture of node types must be reconfigured.

For information about how to prepare your Isilon cluster for upgrade to OneFS 7.0, see the Isilon OneFS 7.0.1 – 7.0.2 Upgrade Readiness Checklist.

EMC Isilon OneFS 7.1.1 is now available!

Kirsten Gantenbein

Kirsten Gantenbein

Principal Content Strategist at EMC Isilon Storage Division
Kirsten Gantenbein
Kirsten Gantenbein

The latest release of the EMC® Isilon® OneFS operating system is now available!

This blog post summarizes noteworthy new features of OneFS 7.1.1, highlights new OneFS 7.1.1 documentation, and provides steps for upgrading to OneFS 7.1.1.

New OneFS 7.1.1 features and enhancements

High-level technical overviews for several OneFS 7.1.1 new features and enhancements are provided below. They’re grouped together by the types of benefits they provide, such as performance improvement and security. Refer to OneFS 7.1.1 Release Notes and Technical Overview of New and Improved Features of EMC Isilon OneFS 7.1.1 for additional details.

Performance improvements

The following new features and enhancements help improve performance for most OneFS workflows:

  • SMB Multichannel support
    OneFS 7.1.1 supports the Multichannel feature of SMB 3.0, which establishes a single SMB session over multiple network connections. SMB Multichannel enables increased throughput, connection failure tolerance, and automatic discovery. To take advantage of this new feature, client computers must be configured with Microsoft Windows 8 or later, or Microsoft Windows Server 2012 or later with supported network interface cards (NICs). For more information, see the SMB Multichannel section of the OneFS 7.1.1 Web Administration Guide and OneFS 7.1.1 CLI Administration Guide.
  • SmartFlash caching
    In OneFS, level 1 (L1) cache uses random access memory (RAM) to store copies of system metadata and files requested from front-end networks. Level 2 (L2) cache uses RAM to store copies of file system metadata for files that are stored on the node that owns the data. SmartFlash, or level 3 (L3) cache, uses solid-state drives (SSDs) to hold file data and metadata released from L2 cache, increasing the total size of cache memory available in a cluster as well as the speed that you can retrieve data. In OneFS 7.1.1, SmartFlash is enabled by default for new node pools.
  • NDMP backup performance improvements
    OneFS 7.1.1 uses multiple threads to restore files, making data transfer occur as fast as the tape backup device can deliver it. Additional operational enhancements improve throughput when transferring small files.
  • SyncIQ® performance enhancements
    To allow multiple SyncIQ workers to replicate a single file simultaneously, SyncIQ now allows for file splitting, where a large file is split into segments, each of which is processed in parallel by a different thread.

Security and access zone enhancements

The following enhancements have been made to increase security and support Hadoop workflows:

  • Access zone enhancements
    Access zones have been restructured to enforce best practices and improve security. In OneFS 7.1.1, a root or a base directory must be designated for each access zone. SMB shares must subscribe to a single access zone, and access zones can no longer be used to share data. OneFS 7.1.1 also prevents access to non-system zones through NFS, SSH, and the OneFS web administration interface.To support security for Hadoop workflows and enable multiple unstructured datasets to be hosted on a single cluster, access zones now support an HDFS namespace per access zone. This means that you can now run multiple separate HDFS namespaces on the same cluster. Stay tuned for an upcoming ISI Knowledge blog post on this topic.
  • Self-encrypting drive enhancements
    This release of OneFS expands the availability of self-encrypting drives (SEDs) to provide data at-rest encryption capabilities across the entire node family. In addition to the 3TB and 4TB SEDs, OneFS 7.1.1 introduces a 900GB SAS SED HDD for S-Series nodes and an 800GB SED SSD for all supported nodes. For details, see the Isilon Product Availability Guide.
  • Auditing enhancements
    In OneFS 7.1.1, audit system configuration information can be forwarded to the audit log file for storage and analysis.
  • Role based access control enhancements
    New privileges have been added to the role based access control (RBAC) feature in OneFS 7.1.1, such as ISI_PRIV_IFS_BACKUP and ISI_PRIV_IFS_RESTORE. These privileges can be assigned to roles that enable users to back up and restore files that they don’t have explicit permissions to.

Manageability and drive firmware updates

The following OneFS 7.1.1 features make it easier to manage your Isilon cluster and obtain the latest drive firmware:

  • MMC integration
    Microsoft Windows administrators with the correct privileges can remotely administer a share through the MMC shared folders snap-in feature. This enables an administrator to connect to an access zone and directly manage all shares within that zone. To take advantage of this functionality, the Isilon cluster must be joined to an Active Directory domain from which the MMC console can be invoked.
  • Drive Support Package for non-disruptive drive firmware updates
    Drive support packages determine and apply updates for the drive’s firmware automatically, and eliminate the need to apply a patch and reboot the node when you replace or add drives. You can also configure alerts to indicate when you need to update your drive firmware. Review the Isilon Drive Support Package 1.0 release notes for information about system requirements and installation instructions.

For complete details about all of the OneFS 7.1.1 features and enhancements, including changes in functionality, fixed issues, and known issues in this release, refer to the OneFS 7.1.1 Release Notes.

OneFS 7.1.1 documentation and new guides available

A full list of OneFS 7.1.1 documents is available in the OneFS 7.1.1 Release Notes, on the Isilon online community and on the EMC Online Support site (login is required for the EMC Online Support site). This release also features two new guides:

  • OneFS Migration Tools Guide
    This guide describes how to migrate data from NetApp filers and EMC VNX storage systems to EMC Isilon clusters using the isi_vol_copy and isi_vol_copy_vnx tools.
  • OneFS API Reference 
    This guide—combining the former Platform and RAN API References—describes how the Isilon OneFS application programming interface (API) provides access to configure the cluster and access the data on the cluster. This guide also provides a list of all available API resource URLs, HTTP methods, and parameter and object descriptions.

How to upgrade to OneFS 7.1.1

OneFS upgrade tip from the Uptime Bulletin newsletter

Kirsten Gantenbein

Each quarter EMC Isilon produces a technical newsletter called the Uptime Bulletin. This newsletter provides product tips and announcements. You can access our first issue of the EMC Isilon Uptime Bulletin (PDF) on the EMC Online Support site (login required).

The first issue includes the following Isilon OneFS tip about upgrading.

Reboot your cluster before an upgrade

Before upgrading to the latest version of OneFS, it helps to be prepared. Assessing compatibility, gathering cluster information, and following best practices during the pre-upgrade window will ensure that the upgrade process goes smoothly.

One of the pre-upgrade steps that EMC Isilon recommends is to reboot your clusters. A reboot ensures a clean state for the upgrade process, and it usually takes fewer than fifteen minutes for simultaneous reboots (where all the nodes in a cluster are restarted at the same time). This recommendation is particularly applicable to clusters that have run a long time without a cluster-wide reboot event.

A cluster reboot can help you to:

  • Identify failing hardware
  • Ensure that cluster configurations, such as share and export configurations, are saved and persist through a reboot
  • Distinguish among problems that might occur either during the reboot process or during the upgrade process

Overall, a pre-upgrade reboot can make it easier for EMC Customer Services to diagnose and resolve any upgrade-related issues quickly. In an ideal upgrade window, you should also test client services after a reboot and before the upgrade. This gives you the opportunity to validate the upgrade verification tests.
