ZFS is Integrated With Fault Manager

Solaris Express Community Release, build 36: This release includes the integration of a ZFS diagnostic engine that is capable of diagnosing and reporting pool failures and device failures. Checksum, I/O, device, and pool errors associated with pool or device failures are also reported.

The diagnostic engine does not include predictive analysis of checksum and I/O errors, nor does it include proactive actions based on fault analysis.

In the event of the ZFS failure, you might see a message similar to the following from fmd:

SUNW-MSG-ID: ZFS-8000-D3, TYPE: Fault, VER: 1, SEVERITY: Major
EVENT-TIME: Fri Aug 28 09:10:27 PDT 2009
PLATFORM: SUNW,Sun-Fire-T200, CSN: -, HOSTNAME: neo
SOURCE: zfs-diagnosis, REV: 1.0
EVENT-ID: d6725ad6-4546-6c48-fa16-eace4d371981
DESC: A ZFS device failed.  Refer to http://sun.com/msg/ZFS-8000-D3 for more information.
AUTO-RESPONSE: No automated response will occur.
IMPACT: Fault tolerance of the pool may be compromised.
REC-ACTION: Run 'zpool status -x' and replace the bad device.

By reviewing the recommended action, which will be to follow the more specific directions in the zpool status command, you will be able to quickly identify and resolve the failure.
