Description Christian Tosta 2003-02-10 13:35:04 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3; Linux)

Description of problem:
I'm implementating quotas for users in a Samba 2.2.7 PDC for Rwindows XP clients. When I run (for example) 'setquota -u 9911054 20000 20000 0 0 /home' the command don't return errors. But when I do a 'quota username' then return "Disk quotas for user #9911054 (uid 9911054): none".

My /home is mounted from /dev/md1 which is a raid0 device spanned into two discs and formatted with ext2 filesystem.

I think is problem the name of the user (a numeric code)??

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Create a numeric username for a new user
2.Set the quota for this user in volume /home (raid0)
3.Check the quota for this user

Actual Results:  Quota is "none" when I check quota for user

Expected Results:  Quota must to be the value I set to user

Additional info:

Problem occur when you try to setup disc quotas for users with a numeric 
username (not specially on raid devices). You need alfa-numeric usernames to 
quota works, otherwise it choose random users to set the quota.

Weellll - None of my usernames are entirely numeric

I'm using redhat 8 with quotas on a new 120G ext3 file system and as I "rsync
-a" files over I notice some usernames aren't showing up in repquota

Once I get a couple of thousand users transferred repquota starts segfaulting

[It's not really a backup, don't worry about the mountpoint name]

[root@backup users]# ls -l /backup/aquota.*
-rw-------    1 root     root         8192 May 12 23:22 /backup/aquota.group
-rw-------    1 root     root       149504 May 12 23:22 /backup/aquota.user

[root@backup users]# repquota /backup
*** Report for user quotas on device /dev/hdc1

Segmentation fault

Is the the same fault? It gets worse as the number of users goes up

Actually the segfault stops when I used the -n flag to repquota

But still not all user-id's show up.
Comment 4 Mark J. Cox (Product Security) 2004-01-05 04:38:53 EST
have you tried this with a later distribution (RHEL 3 or RHL 9)?
Comment 5 Need Real Name 2004-01-05 05:34:35 EST
I've not, its not a box we can update easily.

We since had such bad problems of users reportedly using a large 
quantity of disk space when a "find" for that user reports otherwise 
that we had to rebuild quotas entirely.
