Message-ID: <4C669C93.5000509@pjp.cz> (raw)
Dear,
I have an problem with mdadm based NAS, Unfortunately producer support
don't have any interest to solve anything (Unfortunately as usually).
What's happens - I created 6 HDD array RAID 5 by standard web
interface, because I had an problem with HDD, array was created in order
HDD 2,3,4,5,1,6. After appr. 1.5 year one hdd have problem, some chaos
to understand which hdd had problem (web interface), when I replaced
hdd, array was restore, but in different order of hdd - 2,3,4,5,6,1, hdd
6 and 1 are switch and result - inaccessible array ... unfortunately ...
What I have there - better say no comment.
My small question is simple - exist some solution for this situation
and restore standard work (of course - with (any) data there) ?
