Any Advice? #1 and #2 seem to be the serious issues that no one else has reported yet.

[ovirt-users] 3.6 issues when using an existing gluster volume for the hosted-engine
Hi, I am attempting to setup a Ovirt 3.6 (currently beta 1) on a test environment with an existing (but empty) gluster volume for the hosted engine. I am currently experiencing 4 issues after I having deployed the hosted-engine appliance VM on only 1 oVirt host: 1. The gluster volume is not added as a storage domain by the end of the hosted-engine-setup. 2. When I try to import the gluster volume as a storage domain, I get this error: Error while executing action Attach Storage Domain: AcquireHostIdFailure In the logs below, I had not attempted to import it yet though. 3. The hosted engine VM is not listed, although the host is listed and its number of VMs is listed as "1". (I have seen recent emails/bug reports about what seems to be the same issue.) 4. The hosted VM shut down automatically after several minutes. I last ran ovirt-hosted-engine-setup on galactica on 2015-08-03 at around 22:47 -0400 #4 was probably caused by the fact that during a previous attempt (on 2015-08-02) to setup the hosted-engine, I had /var/lib/ovirt-hosted-engine-ha/ha.conf containing to local_maintenance=True. That value was not changed when I ran ovirt-hosted-engine-setup on 2015-08-03. Today, I ran the hosted-engine command to disable maintenance, and the hosted-engine VM started back up. I can access it over https, but the remaining issues are still present. More Details: The 3 Gluster servers: Server 1: galactica: RHEL 7.1 with Gluster 3.7.3 Server 2: death-star: RHEL 7.1 with Gluster 3.7.3 Server 3: mothership: Fedora 22 with Gluster 3.7.3 I only intend for servers 1 and 2 to be oVirt hosts at this time. All servers have iptables disabled, are on the same LAN, have SELinux set to enforcing, and have gluster configured with the hyper-converged settings listed here: http://www.ovirt.org/Features/Self_Hosted_Engine_Hyper_Converged_Gluster_Support I have DNS forward and reverse lookups configured correctly for all 3 machines plus the hosted engine. The existing gluster volume is "gv-virt", and it has the necessary "options" for gluster to work with oVirt. Other than the .trashcan folder, there were no files/folders on it when I ran ovirt-hosted-engine-setup. I am able to mount and write to gv-virt via mount.glusterfs. Note that I have run hosted-engine-setup repeatedly on servers 1 and 2 as I try to resolve these issues. My cleanup between running it may not have been correct, as exemplified by the local_maintenance setting. I have been deleting the files on the gluster volume between running it. I have the relevant contents of the relevant directories under /var/log/, /var/lib/, and /etc/ here: https://drive.google.com/folderview?id=0B2L_OrCln9ShMWprWVlpZVVocGs&usp=sharing I also put the `gluster volume status gv-virt` output there. Also, these 2 volumes are currently mounted on galactica: galactica.depaulo.org:/gv-virt 200G 2.7G 198G 2% /rhev/data-center/mnt/glusterSD/galactica.depaulo.org:_gv-virt /dev/loop1 2.0G 3.1M 1.9G 1% /rhev/data-center/mnt/_var_lib_ovirt-hosted-engine-setup_tmp2HOqSq Thanks in advance, -Mike ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] Prereqs for Self Hosted Engine Hyper Converged Gluster Support
Hi Didi, 1st of all, note that I am trying this on my home network. This is not a production environment by any means.

Did it continue beyond the "closeup" stage? I ran a total of 25 runs yesterday due to multiple issues that I ran into. The reason why the setup failed seemed to be that the hosted engine VM did not reboot and start up the engine quickly enough, so it failed during health.py. 2015-08-02 14:03:26 ERROR otopi.context context._executeMethod:164 Failed to execute stage 'Closing up': timed out I eventually worked around this by increasing the time.sleep() call to a larger value in the installed health.py, and then recompiling the .pyc and .pyo files. https://github.com/oVirt/ovirt-hosted-engine-setup/blob/c6bc631b81c241c2bf5b5313997e7e575874ac8f/src/plugins/ovirt-hosted-engine-setup/engine/health.py#L161 I think I experienced a bug whereby the while loop is only running 2 or 3 times, but I do not see a bug in the code. Anyway, I planned to send a separate email about this issue, hopefully after I have investigated the possible bug with the loop and prepared a patch. >> I saw the prompt: >> >> Do you want to configure this host for providing GlusterFS >> storage?

[ovirt-users] Prereqs for Self Hosted Engine Hyper Converged Gluster Support
Hi, I am trying to follow these instructions on 3.6 alpha 3: http://www.ovirt.org/Features/Self_Hosted_Engine_Hyper_Converged_Gluster_Support The 1st time I ran ovirt-hosted-engine-setup (which was unsuccessful), I saw the prompt: Do you want to configure this host for providing GlusterFS storage? (Yes, No)[No]: Now I no longer see it. Must gluster not have any peers or volumes already? Is there some other prereq that I am missing?
