I have a zpool thats now showing in a FAULTED state after a power outage rebooted the server & devices names got thrown around. I understand I messed up by adding vdevs by device name, but didnt know it could be changed after creation & populating the pool. Currently the pool is looking for '/dev/sde' (instead of '/dev/sdc') and '/dev/sde' is the device the root fs is on, and im not sure how to approach any recovery without potentially making matters worse.
Hoping there is a way to simply reconfig the zpool to use 'sdc' to be able to export and reimport with 'by-id' naming for avoiding this in future.
root@boxey:~# zpool status
pool: data
state: FAULTED
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.
