Description Abhijith Das 2010-11-30 18:50:47 UTC 
Description of problem:
The generic quota tools that communicate with gfs2 through the quotactl() syscall assume usage/limit/warn values to be in 512B block sizes instead of the fs block size that is assumed by gfs2.

 
Actual results:
The values are all messed up. One can compare the output of gfs2_quota vs that of the values reported by the generic quota tools (repquota, quota, etc.)

Expected results:
The values should tally.
