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).

Fixing product name. Cluster Suite components were integrated into Enterprise
Linux for verion 5.0.
