FAULTED Hard Drive in FreeNAS

So we have 2 faulted hard drives

2. Then run: glabel status:

# glabel status

Example output:

glabel status

This output shows faulted disk numbers – da3p2, da8p2.

Now if you know your hard drive numbers, you can replace disks, or you may need one more step to determine failed disk serial number.

3. To determine serial numbers use smartctl  command:

# smartctl -i /dev/da3
