1005.0. "problem with quotacheck" by MLNCSC::VOCI () Wed Feb 19 1997 02:45
Hello,
a customer has the following problem with ADVFS. He creates a file set, copies
some data and issues the df command, the allocations shown are correct.
He then issues the command quatacheck, after this command the df non longer
shows correct values.
The problem apears using both the quota* and the vquota* commands.
Digital Unix 4.0
Following you'll find the script used to reproduce the problem and the log file.
==========> SCRIPT
#!/bin/csh
set verbose
cd /
umount /u /z
rmfdmn -f marte
mkfdmn /dev/rz1a marte

cp -r /a/lele /z
df -k
chown -R lele /z/lele
du -ks /z/lele
quota -vu lele
quotacheck -av
echo ho finito
df -k
cat /etc/fstab
===========> END SCRIPT
The problem is on marte#f1 and on marte#f2, the df issued before the quotacheck
shows 54MB allocated, this value becomes 1033MB in the output of the second df.

| 1005.1 | Quotacheck -a | NETRIX::"[email protected]" | David Akers | Wed Feb 19 1997 06:07 | 12 |
| This is a known bug and it has been fixed in 4.2 and is being
backported to 4.0.
The problem is in the quotacheck command. When using the -a switch and
having the filesystems set in /etc/fstab with the fsck number > 1. The
fsck number tells quotacheck to run multi-threaded and check each filesystem
in parallel. The quotacheck command has a bug that makes it non-thread safe.
The work around is to either changes the fsck number in /etc/fstab to 1 for
all filesystems or to run quotacheck individually on each filesystem.
