Problem migrating disk attached to the same vg (lvm)

Hi,

I'm trying to migrate the content of disk 'A' to disk 'B', that they belong to the same vg 'data'_vg'. Whe using pvmove, I get the following error: 'device-mapper: suspend ioctl failed: Interrupted system call'. I put down the whole trace:

pvmove -v "source_disk" "sink_disk"

  Updating volume group metadata
    Creating volume group backup "/etc/lvm/backup/data_vg" (seqno 62).
