removing a snapshot that is outside the subvolume directory fails, sorta
Well, it fails the way that I''m trying to do it. kernel: 2.6.31.9-174.fc12.x86_64 btrfs-progs: btrfs-progs-0.19-9.fc12.x86_64 On a new filesystem: $ cd /mnt/btrfs1 $ btrfsctl -S subvol1 . operation complete Btrfs Btrfs v0.19 $ btrfsctl -s snapofsubvol1 subvol1 operation complete Btrfs Btrfs v0.19 $ btrfsctl -D snapofsubvol1 subvol1 ioctl:: No such file or directory $ btrfsctl -S subvol2 . operation complete Btrfs Btrfs v0.19 --------> # cd subvol2 <------------ $ btrfsctl -s snapofsubvol2 subvol2 operation complete Btrfs Btrfs v0.19 $ btrfsctl -D snapofsubvol2 subvol2 operation complete Btrfs Btrfs v0.19 AHA, I figured it out! $ btrfsctl -D snapofsubvol1 subvol1/.. I don''t know if that''s the intended syntax or if it''s accidental, but I''ll go ahead and send this as an FYI if anyone has the same issue. Maybe it''s obvious to some, but it wasn''t to me. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It works only if the "cd subvol2" command is not executed.> $ btrfsctl -D snapofsubvol2 subvol2 > operation complete > Btrfs Btrfs v0.19 > > > AHA, I figured it out! > > $ btrfsctl -D snapofsubvol1 subvol1/.. > > I don''t know if that''s the intended syntax or if it''s accidental, but I''llgo ahead and send this as an FYI if anyone has the same issue. Maybe it''s obvious to some, but it wasn''t to me. Yes it is obvious :-) Because "subvol1/.." is like "." .
