We have a system with two drives in it, part UFS, part ZFS. It's a software
mirrored system with slices 0,1,3 setup as small UFS slices, and slice 4 on
each drive being the ZFS slice.
One of the drives is failing and we need to replace it.
I just want to make sure I have the correct order of things before I do this.
This is our pool:
NAME STATE READ WRITE CKSUM
mainpool ONLINE 0 0 0
mirror ONLINE 0 0 0
c0t0d0s4 ONLINE 0 0 243
c0t1d0s4 ONLINE 0 0 0
1) zpool detach mainpool c0t0d0s4
2) powerdown system, replace faulty drive
3) reboot system, setup slices to match the current setup
4) zpool add mainpool c0t0d0s4
This will add the new drive back into the mirrored pool and sync the new slice
4 back into the mirror, correct?
