Hi,

Yes, you can do something like that, but again, do not include the
journal's blocks. You can do gfs2_edit -p master /dev/sdc to
determine the block of the quota file, which should be past the
journals. Then use that value for the starting point of i.
For example:
# gfs2_edit -p master /dev/mpathc/scratch | grep quota
   8/8 [6c1c0fed] 12/33132 (0xc/0x816c): File    quota
