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.
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.
