Bug#678957: btrfs-tools: snapshot of a subvolume in itself behaves strangely

2012-06-25 Thread Martin Ziegler
Package: btrfs-tools
Version: 0.19+20120328-4
Severity: normal


On the toplevel of a subvolume (or of the btrfs-file system itself)
issue the command

   btrfs subvolume snapshot . xxx

The snapshot xxx now contains itself as an invisible subdirectory,
which becomes visible if we produce a snapshot of xxx:

   btrfs subvolume snapshot xxx yyy

yyy will contain an empty subdirectory xxx. (!)

There is no way to remove the invisible subdirectory from the snapshot
xxx. But yyy/xxx can be removed with rmdir yyy/xxx.

reassign 678957 linux
retitle 678957 btrfs: snapshot of subvolume in itself behaves strangely
thanks

this isn't a bug in the btrfs user-land tool, reassigning to the kernel.

Please forgive my laziness: since you have looked over the bug very
recently, could you provide a quick summary of the symptoms for the
kernel team?  (Based on the subject line it's possible that it is a
duplicate of bug#663067 but don't have the time at the moment to
read the report and check.)

Thanks much,
Jonathan
