As you can see below running “zpool
status” shows me that disk c6d0 has faulted (before you replace the disk you can run "format" to check the serial numbers to make sure you pull out the right disk!!!!)
I replaced the faulty disk, then ran “zpool
replace zfs c6d0” another check of “zpool status” and you can
see the drive is rebuilding (resilvering as it’s called in the ZFS
world).
Run a “zpool
status” in 30 mins or so, this will give you an accurate finish
time, in my case I can see its going to take about 6 and a half
hours.
