[Lustre-discuss] group descriptor corruption

[John White]

I wonder if these errors are generally fixable via an e2fsck:
[root at n0004 ~]# e2fsck /dev/mpath/lun_11 
e2fsck 1.41.10.sun2 (24-Feb-2010)
mako-OST000b: recovering journal
One or more block group descriptor checksums are invalid.  Fix<y>? no

Group descriptor 128 checksum is invalid.  IGNORED.
[...]
Group descriptor 59614 checksum is invalid.  IGNORED.
