Description Tracy Pham 2001-11-15 19:35:54 UTC 
Description of Problem:
The RedHat Linux 2.4.9-7smp kernel can not handle the quota option.
Our server was crashed yesterday due to the quota problem.
Below are the error messages I found it in the log files:

(appologies for the late response but I only just took over the quota package)

Is this still true of the newer kernels? For RH 7.2 that would be kernel-2.4.9-31
If it is, then could you have a shot ar rebuilding and installing

i.e.

ftp://ftp.redhat.com/pub/redhat/linux/rawhide/SRPMS/SRPMS/quota-3.06-2.src.rpm
rpm --rebuild quota-3.06-2.src.rpm
rpm -Uvh /usr/src/redhat/RPMS/i386/quota-3.06-2.i386.rpm

give that a shot and see if that improves the situation

Comment 2 Jan Iven 2002-08-29 09:22:47 UTC 
We have seen the same case with 2.4.9-31 (with addional patches, but not
anywhere near vm /ext3/quota). Happened while converting an ext3 fs to
userquotas, will try to dig out the exact details:
