Witam,
miałem awarię jednego z dysku ( /dev/sdb3 ) w moim NAS z RAID 5. Po wymianie dysku na nowy z automatu poszedł rebuild, który niestety się wysypał z powodu bad sektorów na jednym z dysków ( /dev/sdc3 ). Skończyłem z RAID5 bez jednego dysku i kolejny z rozbieżnością w ilości eventów. Spróbowałem assemeble:
Code:
[~] # mdadm --assemble /dev/md0 /dev/sd[a,c,d]3 --force --verbose
mdadm: looking for devices for /dev/md0
mdadm: failed to get exclusive lock on mapfile - continue anyway...
mdadm: /dev/sda3 is identified as a member of /dev/md0, slot 0.
mdadm: /dev/sdc3 is identified as a member of /dev/md0, slot 2.
mdadm: /dev/sdd3 is identified as a member of /dev/md0, slot 3.
mdadm: no uptodate device for slot 2 of /dev/md0
mdadm: added /dev/sdc3 to /dev/md0 as 2 (possibly out of date)
mdadm: added /dev/sdd3 to /dev/md0 as 3
mdadm: added /dev/sda3 to /dev/md0 as 0
mdadm: /dev/md0 assembled from 2 drives - not enough to start the array.


Chciałbym generalnie w jakikolwiek sposób dostać się do danych, skopiować co się da i sformatować wszystko od nowa.
