Description Peter Rajnoha 2013-09-12 12:43:57 UTC

[root@rhel6-a ~]# pvcreate /dev/sda /dev/sdb
  Physical volume "/dev/sda" successfully created
  Physical volume "/dev/sdb" successfully created

[root@rhel6-a ~]# vgcreate vg /dev/sda /dev/sdb
  Volume group "vg" successfully created

[root@rhel6-a ~]# lvcreate -L2g vg /dev/sda
  Logical volume "lvol0" created

[root@rhel6-a ~]# pvmove /dev/sda /dev/sdb
  /dev/sda: Moved: 0.2%
  /dev/sda: Moved: 15.0%

(REBOOT)

The segfault seen at boot while calling vgchange -ay and also when trying to
run the activation directly on command line:

[root@rhel6-a ~]# lvs
