Hi! I am new to zfs / opensolaris but getting the hang of it. :)
In my setup i have a large zpool called 'backup' which has zfs'es for servers that i backup with rsync. I export those zfs'es via NFS to the remote servers so i have easy access to the most recent backup and the snapshots which i make just before starting the rsync. Recently i switched on 'snapdir=visible' on one of the zfs volumes to easily expose the available snapshots and then i noticed rsync -removes- snapshots even though i am not able to do so myself, even as root, with plain /bin/rm. Example: | r...@host:~# zfs snapshot backup/remoteh...@2009-10-16 | r...@host:~# ls /backup/remotehost/.zfs/snapshot/ | 2009-10-16 | | r...@host:~# /usr/bin/rsync --archive --delete u...@remotehost:/ /backup/remotehost | | [ .. lots of read-only file system errors skipped .. ] | | rsync: delete_file: unlink(.zfs/snapshot/2009-10-16/.history) failed: Read-only file system (30) | cannot delete non-empty directory: .zfs/snapshot/2009-10-16 | deleting .zfs/snapshot/2009-10-16/ | cannot delete non-empty directory: .zfs/snapshot | rsync: delete_file: rmdir(.zfs/snapshot) failed: Operation not applicable (89) | rsync: delete_file: rmdir(.zfs/shares) failed: Operation not applicable (89) | cannot delete non-empty directory: .zfs | | r...@host:~# ls -la /backup/remotehost/.zfs/snapshot/ | total 0 | dr-xr-xr-x 2 root root 2 2009-10-05 09:32 . | dr-xr-xr-x 4 root root 4 2009-10-05 09:32 .. | | r...@host:~# zfs snapshot backup/remoteh...@2009-10-16 | r...@host:~# ls /backup/remotehost/.zfs/snapshot/ | 2009-10-16 What's the deal here. :) I was under the impression that rsync uses unlink() like 'rm' does? How come rsync -can- remove the snapshot directory when exposed with 'snapdir=visible' and i can't do it with /bin/rm?
