mount: /mnt/disk1: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.sdb 8:16 0 36.4T 0 disksdc 8:32 0 36.4T 0 disksdd 8:48 0 36.4T 0 disksde 8:64 0 36.4T 0 diskthis all above showing is one san mount point if i mount /dev/sdb it will show the data if i mount /dev/sdc it will also show the same data. but after server restart i wont able to mount any mount point
i do all the error check command likeanthem@anthem-PowerEdge-R440:~$ sudo fsck /dev/sdbfsck from util-linux 2.37.2e2fsck 1.46.5 (30-Dec-2021)ext2fs_open2: Bad magic number in super-blockfsck.ext2: Superblock invalid, trying backup blocks...fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb
The superblock could not be read or does not describe a valid ext2/ext3/ext4filesystem. If the device is valid and it really contains an ext2/ext3/ext4filesystem (and not swap or ufs or something else), then the superblockis corrupt, and you might try running e2fsck with an alternate superblock:e2fsck -b 8193 ore2fsck -b 32768
then i also try both e2fsck command with /dev/sdb and other mount point of the same san but not working.
