This gives EXDEV for clone operations that btrfs could otherwise execute and with slight change of circumstances will actually execute fine. Imagine we have a btrfs on /dev/mapper/foobar with subvols /foo and /bar. Let’s also imagine top of said fs in mounted at /mnt. In this case, a cross-subvol clone of /mnt/foo/srcfile to /mnt/bar/dstfile will succeed. However, if only the individual

Hi all, Just a quick question but can''t find an obvious answer. Can I create/convert a existing (btrfs) directory into a subvolume? It would be very helpful when transferring ''partitions'' into btrfs. I found a similar question way back in google, but that site is down now generally. Thanks in advance. -- To unsubscribe from this list: send the line
