if you look through the Linux errno header files, you'll find
  -122 is EDQUOT    /* Quota exceeded */
so someone or some group is over quota - either inodes or diskspace.

it would be really good if this message said which uid/gid was over
quota, and from which client, and on which filesystem.
as you have found, the current message is not very informative and
overly verbose.

I was looking at the quota code around this message a few days ago, and
it looks like it'd be really easy to add some extra info to the message
but I have yet to test a toy patch I wrote...

cheers,
robin
