Hi,
One of my server's zfs faulted and it shows following:
NAME STATE READ WRITE CKSUM
backup UNAVAIL 0 0 0 insufficient replicas
raidz2-0 UNAVAIL 0 0 0 insufficient replicas
c4t0d0 ONLINE 0 0 0
c4t0d1 ONLINE 0 0 0
c4t0d0 FAULTED 0 0 0 corrupted data
c4t0d3 FAULTED 0 0 0 too many errors
c4t0d4 FAULTED 0 0 0 too many errors
...(omit the rest).
My question is why c4t0d0 appeared twice, and c4t0d2 is missing.
Have check the controller card and hard disk, they are all working fine.
Please help how to troubleshooting and what is the main cause of it, how to
recover the pool?
Thank you.
