[ovirt-users] 'Sanlock lockspace add failure' when trying to set up hosted engine 4.2 on existing gluster cluster

[Oliver Dietzel]

Install from node iso on gluster works fine, the hosted engine vm installs on gluster, but after installation is finished and rebooted the gluster cluster is not added as data storage.
Hosted engine is able to boot from gluster but not able to use it. Looks like HE doesnt use the gluster volume it booted from, but tries to add the same gluster volume a second time.

Is there a workaround?

Error message in web gui:
VDSM ovirt-gluster.rto.de command CreateStoragePoolVDS failed: Cannot acquire host id: (u'e6d008f7-e5e8-4064-9f6a-6ab7c8723eeb', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argument'))
