can't import - One or more devices are missing from the system

[noabuse]

Hi,

the error occurred after an export, but no disk was removed.
i guess this is the zil device i wanted to add before, but failed.
but why doesn't the id show up anywhere?
is there any way to fix this issue?

Code:

zpool import
   pool: SAS
     id: 6196801299722847075
  state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
        devices and try again.

i guess this is the zil device i wanted to add before, but failed.

You did fail to add the device as a ZIL, you added it as an additional vdev. You need to put it back in the system so the pool can import. Right now, you are missing a vdev and that has broken your pool. I hope you didn't do anything to that device. It has no redundancy, so if it is missing or damaged, you pool is destroyed. It is always best to ask first.

the error occurred after an export, but no disk was removed.

If you didn't remove it, what did you do to the drive you attempted to add as a "ZIL"?
