Actually that sounds very similar, at first this affected only a few Qtrees & Home folders on the two volumes. Toward the end of yesterday afternoon I thought the filer had sorted itself out, this morning it started again around 09:30Hrs and was affecting pretty much all our qtreees & home folders. The problem became apparent yesterday around 13:00Hrs and dropped off around 16:30Hrs, starting again around 09:30hrs this morning but worse! So there may be some correlation between filer workload and this problem. What DFM was reporting and initially alerted one of the guys to there being a problem, was that about a dozen Qtrees were, according to DFM, set at 50Mb. The quotas file had them set to 31.5Gb. When a asked the filer for a quota report it itially told me that the quotas were set to 50Mb as well, after a quota off followed by a quota on I again queried the filer for a quota report, this time it reported the quotas correctly BUT still users couldn't write to their Qtrees or Home folders. I even forced the cluster partner to take over the disks and rebooted the filer having the problem but that dind't resolve it either.

An issue that may be related that I noticed, if I perform a quota resize, it silently drops random users to a default user quota I have specified. If I run quota resize again, it complains about the default user entry. Quotas remain confused like this until I perform a full quota off/on, then quotas seem to operate perfectly fine for me.

Of two filers updated to Data OnTap 7.0.1 Sunday morning, one has now got a Quotas problem.

Users are getting disk full errors when trying to write to Qtrees or Home folders despite have copious amounts of free space. The volumes and disks have space. The Qtrees are on one traditional volume and the Home folders on another traditional volume. When the quotas are off there's no problem.

Have checked the filer is reading the quotas file correctly by doing a rdfile /etc/quotas and comparing to the physical quotas file and it's exact.

Have tried switching on and off the quotas, and also rebooting the filer (it works for MS boxes!)

Have a ticket open with NetApp but so far no resolution.

Anyone experienced anything similar or any ideas on a resolution?
