So my quota tests (219 and 232) still fail (zero output from repquota)
and I realized 2 things:

1. they don't fail with kernel 2.6.38 (Ubuntu 11.4 shipped kernel)

2. what seems to fail is quotaon:

amir@qalab:~/xfstests$ sudo quotaon /mnt/test/scratch
quotaon: using /mnt/test/scratch/aquota.user on /dev/sda8
[/mnt/test/scratch]: No such process
quotaon: Quota format not supported in kernel.

Which also explains why quotaoff was called without quotaon in my
original bug report.

amir@qalab:~/xfstests$ quotaon -V
Quota utilities version 4.00-pre1.
Compiled with: USE_LDAP_MAIL_LOOKUP EXT2_DIRECT HOSTS_ACCESS
ALT_FORMAT RPC RPC_SETQUOTA BSD_BEHAVIOUR
Bugs to jack@suse.cz

Any suggestions?

Amir.

  Hum, how about that you forgot to configure kernel with quota support as
the message suggests? Or that you forgot to enable appropriate quota format
or forgot to load the module (if compiled as such)?

Yes. didn't build the quota format modules.
I wasn't aware that quota support has loadable modules.
I took the shipped Ubuntu config and ran make localmodconfig to make
my build shorter,
so I lost the quota format modules :-)
