[ovirt-users] many dd ioctl messages on the SPM host.

Hi,
I can see many
dd: sending ioctl 80306d02 to a partition!
messages on my CentOS 7.1 SPM host.
I the top I can see that lvm process is using 100%.
My migration from iscsiA to iscsiB storage is terrible slow.
The lvm process always changing its pid.

/sbin/lvm lvextend --config  devices { preferred_names =
["^/dev/mapper/"] ignore_suspended_devices=1 write_cache_state=0
disable_after_error_count=3 obtain_device_list_from_udev=0 filter = [
'a|/dev/mapper/149455400000000007265735f69534353494c6f676963616c|/dev/mapper/360014056427aebd90ef41b1b5df2cd79|',
'r|.*|' ] }  global {  locking_type=1  prioritise_write_locks=1
wait_for_locks=1  use_lvmetad=0 }  backup {  retain_min = 50
retain_days = 0 }  --autobackup n --size 5373952m

Are there some problems with migration?
I am using ovirt 3.5.x with iscsi storage.
