Bug#436960: pvmove does not clean up properly on error

[Goswin Brederlow]

Package: lvm2
Version: 2.02.06-4
Severity: important
File: pvmove

Hi,

I run into a problem with pvmove that seems to be a bug in the kernel:
http://www.redhat.com/archives/linux-lvm/2007-July/msg00037.html

But this isn't about that problem but rather about after:

mrvn at storage:~% sudo lvdisplay -m /dev/e/var
  --- Logical volume ---
  LV Name                /dev/e/var
  VG Name                e
  LV UUID                LqoHJ9-yi1Q-oX5Q-cJWX-Qzfi-Z6Vp-N42zLA
  LV Write Access        read/write
  LV Status              available
  # open                 1
  LV Size                2.00 GB
  Current LE             512
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:0
   
  --- Segments ---
  Logical extent 0 to 511:
    Type                linear
    Logical volume      pvmove0
    Logical extents     0 to 511

mrvn at storage:~% sudo dmsetup table
e-var: 0 4194304 linear 253:10 0
e-pvmove0: 0 4194304 mirror core 1 1024 2 22:65 384 9:1 2097536

As you can see pvmove did setup the mirror device before it
failed. But it doesn't undo that. I did a 'pvmove --abort' manualy and
that seems to have undone the move but I would expect pvmove to do
that automatically.
