FreeBSD 9.0 issues with Quota
There is an issue with FreeBSD 9.0-RELEASE and Quota with a UFS2+SoftUpdate. Apparently it doesn't update the quota file as it should.
I found this in the freebsd-stable mail-list archive.
This is a bug in +J code (even if you do not use +J). Do you have softupdates enabled on the volume ? If yes, try the following patch.
I have tried this patch and it is working as it should!
