I removed my volume group and recreated it with -c y, but I still can't
create a volume:

[root at omadvnfs01a ~]# vgcreate -c y vg_data01e /dev/sdc1
  Volume group "vg_data01e" successfully created
[root at omadvnfs01a ~]# lvcreate --size 4T -n lv_data01e vg_data01e
  Error locking on node omadvnfs01b: device-mapper: create ioctl failed:
Device or resource busy
  Aborting. Failed to activate new LV to wipe the start of it.

my locking type is 3.


It looks like the VG got created on both nodes:
on A node:
  --- Volume group ---
  VG Name               vg_data01e
  System ID
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  5
  VG Access             read/write
  VG Status             resizable
  Clustered             yes
  Shared                no
  MAX LV                0
  Cur LV                0
  Open LV               0
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               4.00 TB
  PE Size               4.00 MB
  Total PE              1048578
  Alloc PE / Size       0 / 0
  Free  PE / Size       1048578 / 4.00 TB
  VG UUID               rT2b6W-OAsO-fBm7-je9M-dH7W-emvR-ehkU4z

on node B:
  --- Volume group ---
  VG Name               vg_data01e
  System ID
  Format                lvm2

  MAX LV                0

  Cur PV                1
  Act PV                1
  VG Size               4.00 TB
  PE Size               4.00 MB
  Total PE              1048578
  Alloc PE / Size       0 / 0
  Free  PE / Size       1048578 / 4.00 TB
  VG UUID               rT2b6W-OAsO-fBm7-je9M-dH7W-emvR-ehkU4z


Any ideas?
