I have a disk that smart long test reported read error, the pool state is online, status: One or more devices has experienced an unrecoverable error.
I read the documents, and there is a note:
Is that mean I can put the new disk in another slot and just select replace without take the failed disk offline, or I should take the failed disk offline without removing, and then select replace disk?
Thanks!
I read the documents, and there is a note:
A disk that is failing but has not completely failed can be replaced in place, without first removing it. Whether this is a good idea depends on the overall condition of the failing disk. A disk with a few newly-bad blocks that is otherwise functional can be left in place during the replacement to provide data redundancy. A drive that is experiencing continuous errors can actually slow down the replacement. In extreme cases, a disk with serious problems might spend so much time retrying failures that it could prevent the replacement resilvering from completing before another drive fails.
Is that mean I can put the new disk in another slot and just select replace without take the failed disk offline, or I should take the failed disk offline without removing, and then select replace disk?
Thanks!
