[Users] SD Disk's Logical Volume not visible/activated on some nodes

[John Taylor]

I want to jump in here and say I'm seeing the same thing.
ovirt 3.3.2  on f19
hosts  are vdsm 4.13.3-3.fc19

I'm using storage domain iscsi (fujitsu eternus) with 4 hosts. I've
known about the warning with the vg_mda_free ( I asked on lvm with no
response https://www.redhat.com/archives/linux-lvm/2014-February/msg00033.html
) but until now I didn't verify the problem with not seeing the lvs.
My test was create a standalone disk on the iscsi sd. The lv only
shows on the spm where it was created. None of the other 3 hosts show
it.   multipath -r on a non-spm host causes it to show up.
