I have a user who according to ZFS is at their quota. However, I cannot find how they are using all of their space. This file system has no descendant file systems and according to the man page
the userquota space calculation does not include space that is used by descendent datasets, such as snapshots and clones. Why do zfs and find&du disagree to such a large extent?
# zfs get -H userquota@user1 zpool/zfs1 && zfs get -H userused@user1 zppol/zfs1 zpool/zfs1 userquota@user1 20G local zpool/zfs1 userused@user1 20.0G local # find $(zfs get -H -o value mountpoint zpool/zfs1) -user user1 -print0 | du -hc --files0-from=- | tail -n 1 5.9G total
Additionally, I have another user with seemingly the opposite problem.
# zfs get -H userquota@user2 zpool/zfs1 && zfs get -H userused@user2 zpool/zfs1 zpool/zfs1 userquota@user2 50G local zpool/zfs1 userused@user2 14.9G local # find $(zfs get -H -o value mountpoint zpool/zfs1) -user user2 -print0 | du -hc --files0-from=- | tail -n 1 81G total
