Good morning, one of four hds in my LVM2 raid has stopped reacting to SMART commands or anything else. The 16 TB raid system contains four 8 TB hds in a RAID 1 set of two RAID 4 pairs:
RAID 1 ┌ RAID 4 ┌ A
│ └ B ← needs to be replaced
│ RAID 4 ┌ C
└ └ D
So I need to replace hard disk B, buy a new disk and integrate it.
Should I replace disk A, too, as it is of the same age? If not, should the
replacement B be larger so that in the future I can grow the array? Should I
get an HDD or an SSD?
Any tips on the choice of hard disk (size, parameters, maker) as well as on the
procedure would be much appreciated.
