[zfs-discuss] How to replace root drive if ZFS data is on it?
Hi, Experts:
A customer has X4500 and the boot drives mirrored (c5t0d0s0 and
c5t4d0s0) by SVM,
The ZFS uses the two other partitions on these two drives(c5t0d0s3 and
c5t4d0s3).
If we need to replace the disk drive c5t0d0, do we need to do anything
on the ZFS
(c5t0d0s3 and c5t4d0s3) first or just follow the regular boot drive
replacement procedure?
Below is the summary of their current ZFS file system on X4500:
