I messed up my raid5 array . I know a two of HDs are "failure
prediction" and one is out.. seagate is shipping me replacements.
This is my backup server so there's the actual copy of data but I'd
prefer to recover the array because other data scripts/tools have crept
into it ... mostly junk but would like to verify.
Here's out put as recommended at
https://raid.wiki.kernel.org/index.php/Linux_Raid
Thanks in advance for any assistance,
TOm
