Hi Pattabhi,
Hello All,
I have just enabled quotas on one of my GFS file system, but when i
run the gfs_quota list -f /GCSHome command it gives me the output of
the command and gets stuck, meaning it does not return back to the
prompt. i have to press a ctrl C to get back to the prompt.
And idea what is happening here??
This bug was fixed in the latest version of gfs_quota. Please update
your packages accordingly.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=210362
The quota file is a hidden sparse file and quota information for
users/groups is stored at offsets derived from their userids/groupids
within the quota file. eg: For a userid x, the quota information would
be at an offset 2*x*QSIZE, where QSIZE is the size of the quota
information. Large parts of the quota file is sparse; holes with no
valid quota information.
For the list operation gfs_quota scans through the entire quota file
(holes and all) and only displays valid quota information.
Accidentally or intentionally assigning quota information for a big
userid/groupid (value x from the above example) you essentially make the
filesize 2*x*QSIZE. where x is a really big number.
It takes forever for gfs_quota to scan this huge file and gives the
impression that it's hung.
gfs_quota is now smarter, in that, it skips all the holes in the quota
file and reads only valid information.
Hope this helps.
Pattabhi Raman
