action

For an active pool

If this error was encountered while running 'zpool import', please see the section below. Otherwise, run 'zpool status -x' to determine which pool has experienced a failure:

# zpool status -x
  pool: test
 state: FAULTED
status: One or more devices could not be opened.  There are insufficient
	replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.
   see: https://illumos.org/msg/ZFS-8000-3C
 scrub: none requested
config:

        NAME                  STATE     READ WRITE CKSUM
        test                  FAULTED      0     0     0  insufficient replicas
          c0t0d0              ONLINE       0     0     0
          c0t0d1              FAULTED      0     0     0  cannot open

errors: No known data errors

If the device has been temporarily detached from the system, attach the device to the system and run 'zpool status' again. The pool should automatically detect the newly attached device and resume functioning. You may have to mount the filesystems in the pool explicitly using 'zfs mount -a'.

If the device is no longer available and cannot be reattached to the system, then the pool must be destroyed and re-created from a backup source.

For an exported pool

If this error is encountered during a 'zpool import', it means that one of the devices is not attached to the system:

# zpool import
  pool: test
    id: 10121266328238932306
 state: FAULTED
status: One or more devices are missing from the system.
action: The pool cannot be imported.  Attach the missing devices and
	try again.
   see: https://illumos.org/msg/ZFS-8000-3C
config:

        test              FAULTED   insufficient replicas
          c0t0d0          ONLINE
          c0t0d1          FAULTED   cannot open

The pool cannot be imported until the missing device is attached to the system. If the device has been made available in an alternate location, use the '-d' option to 'zpool import' to search for devices in a different directory. If the missing device is unavailable, then the pool cannot be imported.
