[linux-lvm] Problem with pvmove and linux 2.6.0-test8, lvm2



Hi.

I'm having some problems with a newly created volume group.
I got 3 harddisks and I want to remove one of them so I just
use pvmove like with lvm version 1.

Here is the output from pvmove:

thriller ~ # pvmove -i 5 -v /dev/hda12
    Finding volume group "data"
    Archiving volume group "data" metadata.
    Creating logical volume pvmove0
    Moving 274 extents of logical volume data/lvol1
    Found volume group "data"
    Found volume group "data"
    Updating volume group metadata
    Creating volume group backup "/etc/lvm/backup/data"
    Found volume group "data"
    Found volume group "data"
    Loading data-pvmove0
  device-mapper ioctl cmd 9 failed: Invalid argument
  Couldn't load device 'data-pvmove0'.
  ABORTING: Temporary mirror activation failed.
    Found volume group "data"
    Loading data-lvol1
  device-mapper ioctl cmd 9 failed: Invalid argument
  Couldn't load device 'data-lvol1'.

Now any access on the device blocks until I do "pvmove --abort" which I
think is very bad. "pvmove --abort" says:

thriller ~ # pvmove --abort
  Unable to unlock logical volume "pvmove0"

"lvm version" says:

  LVM version:     2.00.07 (2003-09-16)
  Library version: 1.00.05-ioctl-cvs (2003-09-01)
  Driver version:  4.0.0

Finally "vgdisplay -v" says:

thriller ~ # vgdisplay -v
    Finding all volume groups
    Finding volume group "data"

Is this a bug in lvm2 or devicemapper or a kernel bug? Or am I doing
something wrong?

TIA and bye

Frank Benkstein.
