Hello,
Is quota support currently broken?
Under 2.5.54 I got:
# quotaon /
using //aquota.user on /dev/hda1: No such device
/dev/hda1 is ext3 and aquota.user exists on it.
My config is:
CONFIG_QUOTA=y
# CONFIG_QFMT_V1 is not set
CONFIG_QFMT_V2=y
CONFIG_QUOTACTL=y

It works for me.

this one works ok. quotacheck -m -F vfsv0 / seems to be working

quotaon / freezes process if system is up in normal mode. More over any process
cannot read nor write to disk after that. sysrq-p shows cpu in idle only.
when init=/bin/sh then it reports no such device.
under 2.5.53 and 2.4.20 quotaon works ok. Under 2.5.53 quotaoff / reports some
error - no such device or bad ioctl I cannot remember exactly but process does
not freeze.

I seems like quotaon (or better quotactl()) waits on some lock
forever... I'll try to reproduce it but in the mean time can you print
list of processes, write down a few addresses from the top of the stack
of quotaon and try to match it in the system.map to function in which
is process stuck?

Hmm.. This might be helpful. Thanks.

Thanks for report

according to strace quotaon freezes at
quotactl(0xff800002, "/dev/hda1", 2
call trace is: (sysrq-t)
vfs_permission
__rwsem_do_wake
rwsem_down_read_failed
module_put
dqinit_needed
vfs_quota_off
resolve_dev
d_free
deny_write_access
check_quotactl_valid
d_free
scheduling_functions_start_here
do_quotactl
system_call
Btw, freeze on quotaon is not regular. After some time that system is up,
quotaon reports only no such device and terminates.
so looks like
1) freeze on quotactl
2) reports no such device
in both cases not working.

Reporting 'No such device' was actually bug which was introduced some
time ago but nobody probably noticed it... It was introduce when quota
code was converted from device numbers to 'bdev' structures.
I also fixed one bug in quotaon() call however I'm not sure wheter it
could cause the freeze. Anyway patch is attached, try it and tell me
about the changes.

Hmm, quotaon / with init=/bin/sh seems to work OK, quota accounting is made and
repquota displays normal info.
However with normal startup quotaon / still freezes :-(
Btw, does anyone know why mount is failing for so long time while using with
automount? Process mount is in uninterruptible sleep for more than 10 secs until
reports no disc in cdrom. (the same for my usb camera when autofs try to mount
it while it is not connected).

OK, so one bug fixed.

:( So I'll search for more bugs...

Ok. So I found the bug. Fix was a bit nontrivial (at one path we tried
to acquire one lock twice) but know it should work. The patch also
contain fix in ext2 - at some time ext2_setattr was written and call of
DQUOT_TRANSFER was missing so no quota was being transferred.
Please test whether the patch works for you.

PS: First patch is the one I already sent you.

Good job. This patch works for me (tested with kernel 2.5.55, successfully
patched with no errors). Thanks a lot.
