Issue

The fsck.gfs2 command failed with error when trying to fix a gfs2 filesystem:

    [root@node42 ~]# fsck.gfs2 -a /dev/vg_data/lv_data
    Initializing fsck
    Validating resource group index.
    Level 1 resource group check: Checking if all rgrp and rindex values are good.
    (level 1 failed: Some damage was found; we need to take remedial measures)
    Level 2 resource group check: Checking if rindex values may be easily repaired.
    The rindex file does not meet our expectations.
    (level 2 failed at block 0 (0x0): rindex is unevenly spaced: either gfs1-style or corrupt)
    Level 3 resource group check: Calculating where the rgrps should be if evenly spaced.
    [....]
    New resource groups:
    L3: number of rgs in the index = 121886.
    L3: number of rgs expected     = 121886.
    Level 3 didn't work.  Too many discrepancies.
    121886 out of 121886 rgrps (100 percent) did not match what was expected.
    (level 3 failed at block 0 (0x0): rindex calculations don't match: uneven rgrp boundaries)
    Level 4 resource group check: Trying to rebuild rindex assuming evenly spaced rgrps.
