Let me address your questions and replies. > That doesn't sound like a filesystem problem. Sounds more like the > remote user/group configuration is getting squashed.

Stracing shows that the group and user ID's are not being squashed and they are resolving each time to their respective UID/GID's. > As it is, describing the problem in text doesn't tell me anything > about the problem.

I figured before sending the usual gamut of console "action", I'd "save" time by simply presenting the symptoms. > I can't see how that is related to the filesystem - the filesystem > will either account for group quota usage or it won't.

I can tell you that running the quota report does show the group block count changing. It looks like this "issue" is my misunderstanding of how XFS is checking the quota. Perhaps you could shed some light? When you're using active user and group quotas on the same file system and the user quota is lower than the group quota, does XFS first check against the user quota and then the group quota? Is the order of operations user, group, and then project or does it depend on the mounting order of quotas? In the case I presented yesterday, the user in question had a quota of 25 GB, but the group had an unlimited quota. Each time that I used sudo -u user -g group or logged into the user's account, the quota was always exceeded. Now that I have removed the user's quota, the group quota is now being respected properly. Again, thank you!
