CentOS 6 : Group descriptors corrupted


This Content is from ServerFault. Question asked by supmethods

I found the following in dmesg and I am wondering what I can do to fix it: EXT4-fs (snumbd1d): group descriptors corrupted!.

Will I need to take the server offline in order to recover the file system or is it possible to do it without taking the server offline?

EXT4-fs (snumbd1d): ext4_check_descriptors: Checksum for group 128 failed (22619!=896)
