Hi,
can somebody who is aware of ext4 and quota have a look on this one?
This was also just reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=521914
Checked the bugzilla, it seems the fs enabled quota, but no user quota
limit is specified. Is this the case with the ext4 quota+ nfs issue too?
If no user quota is specified, then IS_NOQUOTA() should avoid doing
quota reservation/claim at all. Not sure what is missing... I will check
if I could reproduce this on local filesystem...
Thanks,
Mingming
yes, FS has quota just enabled and only initial quotacheck was done

Hello,
recently we have build and started to use raid storage with formatted
capacity of 4.5T (ext4 formatted, default params).
FS has quota turned on and is exported via NFS to nodes.
If we turn qouta on on this FS and are trying to use it over NFS we get the
following:

qith quotaoff on tihs FS, warnings stop.
Question is if it's safe to use quotas with this problem (warning) or not.
Can't afford data damage.
