I've just started using ZFS on linux and have already run into problems.
I connected my old data drive to my server to copy my data to my new ZFS volume. However, when I removed this drive and rebooted Linux, I found that my devices had been renumbered and ZFS could no longer mount its pool.
zpool status
pool: media
state: UNAVAIL
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: http://www.sun.com/msg/ZFS-8000-3C
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
media UNAVAIL 0 0 0 insufficient replicas
raidz1-0 UNAVAIL 0 0 0 insufficient replicas
sdc FAULTED 0 0 0 corrupted data
sdd FAULTED 0 0 0 corrupted data
sde UNAVAIL 0 0 0 cannot open
The devices are now sdb,sdc,sdd. What can I do rename the devices? I'm using Ubuntu 11.04.
