Troubleshooting ZFS Storage Pool Issues

    Review the following new diagnostic descriptions and features:

  • Failed devices – Review the zpool status –l output to identify the physical location of the failed device and replace it. For information about replacing a failed disk, see Replacing or Repairing a Damaged Device in Managing ZFS File Systems in Oracle Solaris 11.2 .

  • Failed device notification – The smtp-notify service can be configured to send electronic mail notifications in response to various fault management events, such as when a hardware component has been diagnosed as faulty. See the notification parameters section of smf (5) .

    By default, some notifications are set up automatically to be sent to the root user. If you add an alias for your user account as root in the /etc/aliases file, you will receive electronic mail notifications.

  • Moving devices – Devices that are part of a ZFS storage pool contain a device ID if the device driver creates or fabricates device IDs. Like all file systems, ZFS has a very close relationship with its underlying devices. If you attempt to upgrade a system's firmware, move a pool device to a different controller, or change a device's cabling, you might consider exporting the pool first. If the device ID does not follow the device change and this can happen with non-Oracle hardware, then the pool and pool data might become unavailable. In general, Oracle's Sun hardware can recover if a device is changed under a live pool because these drivers fully support device IDs. However, you might consider exporting the pool before making any hardware changes.
