If (some of) the disks have RAID metadata on them, be very careful

I don't 'do' RAID (never needed to outside RAID 1 on Tandem NonStop and
Stratus fault tolerant systems, but apart from suggesting gparted or fsck
repairs (WHICH THE OP CAN EASILY IGNORE), everything else I suggested is,
or should be, read-only. How could read-only checks mess up RAID metadata?

Colour me genuinely puzzled: an explanation would be appreciated.

What I described (looking at what gparted, fsck and smartd have to say)
is no more and no less that what I do routinely to hopefully spot failing
disks before they break.
