Whats the best way to exchange a raid5 disc (5 discs, xfs) in omv? Its still working but needs replacement due to smart status.
I plan to put in another sas controller so i can add the drive to the raid as spare and do a replacement, my current controller has no more free ports.
I assume this will lead to a faster rebuild time and less stress for the remaining drives then to put out the drive, put in the new one and do a rebuild/resync.
Can this be done with the gui?
With mdadm it would be somehow like that:
# mdadm /dev/md0 --add /dev/sdf1
# mdadm /dev/md0 --replace /dev/sda1 --with /dev/sdf1
---
I wonder what happens when i remove the 2nd temporary controller again. The new drive will become sda1 instead of sdf1. How should i handle this?
