Hello all, Recently have some problem with swap partition :messed:, After installing the 12.1 setup my disks as RAID as usual with this configure:
30GiB x2 RAID 1 root
1GiB x2 RAID 1 swap
Rest RAID 0 home
linux-4m4t:/home/hamed # dumpe2fs /dev/md1
dumpe2fs 1.41.14 (22-Dec-2010)
dumpe2fs: Bad magic number in super-block while trying to open /dev/md1
Couldn't find valid filesystem superblock.
linux-4m4t:/home/hamed # mdadm --examine --scan
