Which version of ovirt 3.3 is this? (3.3.2? 3.3.3?)
ovirt-engine is 3.3.2-1.fc19

How do you know it is not seen on host2?
It's not present in the output of vgdisplay -v nor vgs.

When you create a new lv on the shared storage, the new lv should be
visible on the other host. Lets start by verifying that you do see
the new lv after a disk was created.=20
=20
Try this:
=20
1. Create a new disk, and check the disk uuid in the engine ui
2. On another machine, run this command:
=20
lvs -o vg_name,lv_name,tags
=20
You can identify the new lv using tags, which should contain the new di=
sk uuid.
=20
If you don't see the new lv from the other host, please provide /var/lo=
g/messages
and /var/log/sanlock.log.
Just tried that. The disk is not visible on the non-SPM node.
On the SPM node (where the LV is visible in vgs output):

On the non-SPM node (the one that doesn't show the LV in vgs output),
there are no relevant entries in /var/log/messages. Here's the full
