Hey experts, I've been with this error for the past 2 days trying to find a way around it, but so far nothing seems to be working for me.
Basically, after a reboot (shutdown -r now), the server is not recognizing the second and third HDD's partition, it cannot be mount. The /dev/sdb1 partition is not present anymore and it's where I had about 600GB of data, and /dev/sdc1 was the backup hard-drive which has the partition present but it does not mount. Check the error message:
[root@jumbo ~]# fsck -fy /dev/sdb
fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Group descriptors look bad... trying backup blocks...
fsck.ext4: Bad magic number in super-block when using the backup blocks
fsck.ext4: going back to original superblock
fsck.ext4: Device or resource busy while trying to open /dev/sdb
Filesystem mounted or opened exclusively by another program?
lsof /dev/sdb, doesn't return anything.
Same happens for the /dev/sdc device
I tried running the following for each superblock:
fsck.ext4 -p -b <superblock> -B 4096 /dev/sdb
But it didn't seem to work.
Has anyone encountered the same error and found a fix or a work around? I'm running out of options here and since both drives are not mounting and 600GB of data short.
Hard Drives are healthy, reporting no errors.
SATA cable was changed to new ones, and still nothing.
Would really appreciate your input.
