Description Abhijith Das 2007-01-29 18:41:37 UTC

Description of problem:
gfs_quota list -f /fs/path appears to hang when the hidden quota file becomes an
unmanageably large sparse file. Duplicate of RHEL4 bug bz210362

The gfs_quota tool sequentially reads the quota file ignorant of large holes in
the quota file which takes a lot of time. The gfs_quota tool needs to
intelligently skip the holes in the file and only read quota file information
that's on actual data-filled blocks.

Comment 1 Abhijith Das 2007-04-04 21:39:51 UTC

cvs commit -m "fix for bug 225199 - Same as GFS1 fix in RHEL4 (bug 210362). We
don't run throug the entire gfs_quota sparse file to do a list operation
anymore. We get the layout of the gfs_quota file on disk and only read quota
information off the data blocks that are actually in use. Also added
functionality to GFS_IOCTL_SUPER to provide the metadata of the hidden quota
file." gfs-kernel/src/gfs/ioctl.c gfs/gfs_quota/layout.c gfs/gfs_quota/Makefile

This fix takes care of the problem in gfs1. But the issue still exists for GFS2
(bug 235299).
