Re: Fw: [lenzberger@gmail.com: [suse-security] SuSE 9.1 + quota = deadlock]

22 Oct 2005

      Hi,

sorry, i know that the information given by me was very poor.

i am running reiserfs and the device is listed in fstab this way:
/dev/hda2            /                    reiserfs   acl,user_xattr,usrquota 1 1

i found some posts about this kind of problem when having acl
activated (even when not in use). but the strange thing is, that we
never had this problem on this machine before. i know, that users
reached their quota limit without problems. i think that it will have
to do with one of the last kernel upgrades on suse 9.1 (or maybe some
other packages?)

some information i found (maybe the same thing):
http://marc.theaimsgroup.com/?l=reiserfs&m=112170574830590&w=2

the first time we saw this bug on 2005-09-20 on our system. it does
not happen very often that our users reach their quota limit but now
we see that problem once or twice a week.

so it could be a problem since that update:
-rw-r--r--  1 root root  9144 Sep  3 16:05 kernel-52369

any help would be fine - thank you.

Hello,
is there some bugzilla entry for this problem? If not, then please
create one... Also some questions: do you use acls or extended
attributes? Which filesystem do you use? Have you tried to reproduce the
problem with some newer kernel? By what do you judge that the bug is
'known' - if you point me to some place where this was discussed I have
better chance of remembering how I fixed that in newer kernels ;).
Bye

Subject: [suse-security] SuSE 9.1 + quota = deadlock
we are running suse 9.1 using userquota but something strange happens
when a user reaches his limit (for example with vsftpd).
the task accessing the file hangs in state "D" - no access to the
directory is possible. kill or killall won't help - only rebooting the
machine helps until a user reaches his limit again...
seems to be an old known bug - but this one should be already fixed?!?
currently we are running:
Linux version 2.6.5-7.201-default (geeko@buildhost) (gcc version 3.3.3
(SuSE Linux)) #1 Thu Aug 25 06:20:45 UTC 2005
please help - thank u!
