S/W Raid-5 set degraded by faulty disk

[LFi]

how disks are replaced is dependent on the RAID card functionality. With adaptec I know it should be able to accept a new drive and add it to raid array automatically. If you need to first initialize or such you'd have to use the GUI/CLI for raid card.

You can add disk independently from the RAID. It will be as separate logical volume. Just add the disk hit scan and create LV.

If you want to add it to the RAID. scan it, check it and add it to the RAID. Almost every single RAID card let you do this..

should be able to replace disk
rescan
then add new disk to array
rebuilding should start

Eventually it was indeed replace disk and add disk as hotspare, Rebuilding started automagically/
