Reviewing ZFS Storage Pool Status Information
ZFS storage pool status information is displayed by using the zpool status
command. For example:
$ zpool status pond
pool: pond
state: DEGRADED
status: One or more devices are unavailable in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or 'fmadm repaired', or replace the device
with 'zpool replace'.
Run 'zpool status -v' to see device specific details.
