I am using a a Ready NAS storage in which I set up some LUNs. I mounted one in my email server and another in my backup server. It was working great however few days I go I configured a server with windows Server 2008 and formatted a new LUNs with NTFs (which was previously created on the NAS) surprisingly after that my other 2 LUNs got corrupted. I tried this:
1. Mount the partition again
However I got this message:
"mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
2. Tried fsck
One or more block group descriptor checksums are invalid.
By the way, the partitions where formatted using ext4. Besides, I got snapshots from the NAS.
Please help me recover this data, its very important!.
