Bug#376283: lvm2: pvmove doesn't work

[Dennis Jørgensen]

Package: lvm2
Version: 2.02.06-2
Severity: normal


Hello


I'm trying to migrate data of a disk, but pvmove dies:


dnj at ponder:~$ sudo modprobe dm-mirror
dnj at ponder:~$ sudo pvmove -v /dev/hda6
    Wiping cache of LVM-capable devices
    Finding volume group "vg1"
    Archiving volume group "vg1" metadata (seqno 75).
    Creating logical volume pvmove0
    Moving 19310 extents of logical volume vg1/space
    Moving 0 extents of logical volume vg1/home
    Found volume group "vg1"
    Updating volume group metadata
    Creating volume group backup "/etc/lvm/backup/vg1" (seqno 76).
    Found volume group "vg1"
    Found volume group "vg1"
    Suspending vg1-space (254:0)
    Found volume group "vg1"
    Creating vg1-pvmove0
    Loading vg1-pvmove0 table
  device-mapper: reload ioctl failed: Invalid argument
  ABORTING: Temporary mirror activation failed.  Run pvmove --abort.
    Found volume group "vg1"
    Loading vg1-pvmove0 table
  device-mapper: reload ioctl failed: Invalid argument
    Loading vg1-space table
  device-mapper: reload ioctl failed: Invalid argument
dnj at ponder:~$ pvmove --abort
  /etc/lvm/.cache: open failed: Permission denied
  No volume groups found
  /etc/lvm/.cache: fopen failed: Permission denied
dnj at ponder:~$
dnj at ponder:~$ sudo pvmove --abort


It hangs on the abort. I need to reboot and run pvmove --abort
again to get the "space" LV alive again, it doesn't hang on abort
after reboot.

Heres a bit more info on the setup:
