Ah-ha! Group quota! We hadn’t even set group quotas, but it appears the system tracks the usage anyway when you mount with -o quota. Some googling turned up the following document:

http://seer.entsupport.symantec.com/docs/277535.htm

So it turns out there’s a 1TB maximum limit when using quotas. Since we weren’t using group quotas the simple option was to disable them:

vxquotaoff -gv /cluster/ResFS

Then I edited the Mount resource and changed the quota mount option to usrquota.

This only alleviates the problem for a while. Eventually someone will need to use 1TB of storage for themselves, but hopefully that’s a little way off yet. Maybe we’ll be using ZFS by then anyway
