I would also guess project quotas is involved.That is a behavior that we adopted from upstream ext4 and XFS, but it isn't clear that it is necessary. It would be better to transfer the quota to the new project in the target directory, which is not different than EXDEV triggering "mv" to copy the file in userspace except that it avoids copying the data for large files.I've filed https://jira.whamcloud.com/browse/LU-13176 for this issue.On Jan 28, 2020, at 14:07, Colin Faber <[email protected] <mailto:[email protected]>> wrote:Can you describe your setup with a little more detail?

The clients are either 2.10 or 2.12. The file system is run by 2.12.2 on zfs. nodemap is not active.
