Fixing failed ZIL

[Gorgot]

Hi,

I have a ZIL that failed. I replaced the device, however, I can't seem to replace the ZIL in the zpool configuration.

Here is the current zpool status:

Code: Select all

zpool status
  pool: data
 state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

Here are some of the thing I tried:

Code: Select all

zpool offline data 1603975256220764110
cannot offline 1603975256220764110: log device has unplayed intent logs

Code: Select all

zpool detach data 1603975256220764110
cannot detach 1603975256220764110: no valid replicas

Code: Select all

zpool remove data 1603975256220764110
cannot remove 1603975256220764110: operation not supported on this type of pool

Code: Select all

zpool remove data /dev/da1
cannot remove /dev/da1: operation not supported on this type of pool

I'm starting to get out of commands to run on the pool to get it back to a non-degraded state. Do you have any ideas?

[sleid]

# zpool online data /dev/da1
# zpool clear data

[Gorgot]

# zpool online data /dev/da1
# zpool clear data

Code: Select all

# zpool online data /dev/da1

warning: device '/dev/da1' onlined, but remains in faulted state
use 'zpool replace' to replace devices that are no longer present

# zpool clear data
# zpool status

  pool: data
 state: DEGRADED
status: One or more devices is currently being resilvered.  The pool will
        continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

Unfortunately, the pool is still DEGRADED

wait until resilver done.
