New code is out- Version 2011.1.3.0


The newest version of the ZFSSA code, 2011.1.3.0, is now out and availiable on MOS.

I will be writing more about one of it's many new, useful features coming early next week. It's very cool, and has to do with how you can now change the size of your analytic datasets.


ak-2011. Release Notes


This minor release of the Sun ZFS Storage Appliance software contains significant bug fixes for all supported platforms. Please carefully review the list of CRs that have been addressed and all known issues prior to updating.

Among other issues, this release fixes some memory fragmentation issues (CRs 7092116 and 7105404), includes improvements to DTrace Analytics, and failover improvements to DNS, LDAP, and the SMB Domain Controller.

This release requires appliances to be running the 2010.Q3.2.1 micro release or higher prior to updating to this release. In addition, this release includes update health checks that are performed automatically when an update is started prior to the actual update from the prerequisite 2010.Q3.2.1 micro release or higher. If an update health check fails, it can cause an update to abort. The update health checks help ensure component issues that may impact an update are addressed. It is important to resolve all hardware component issues prior to performing an update.

Deferred Updates

When updating from a 2010.Q3 release to a 2011.1 release, the following deferred updates are available and may be reviewed in the Maintenance System BUI screen. See the "Maintenance:System:Updates#Deferred_Updates" section in the online help for important information on deferred updates before applying them.

1. RAIDZ/Mirror Deferred Update (Improved RAID performance)
This deferred update improves both latency and throughput on several important workloads. These improvements rely on a ZFS pool upgrade provided by this update. Applying this update is equivalent to upgrading the on-disk ZFS pool to version 29.

2. Optional Child Directory Deferred Update (Improved snapshot performance)
This deferred update improves list retrieval performance and replication deletion performance by improving dataset rename speed. These improvements rely on a ZFS pool upgrade provided by this update. Before this update has been applied, the system will be able to retrieve lists and delete replications, but will do so using the old, much slower, recursive rename code. Applying this update is equivalent to upgrading the on-disk ZFS pool to version 31.
