Gluster Install Fail again :(
by admin＠foundryserver.com 30 Oct '21

30 Oct '21

I have been working on getting this up and running for about a week now and I am totally frustrated. I am not sure even where to begin. Here is the error I get when it fails, TASK [gluster.features/roles/gluster_hci : Create the GlusterFS volumes] ******* An exception occurred during task execution. To see the full traceback, use -vvv. The error was: NoneType: None failed: [storage1.private.net] (item={'volname': 'engine', 'brick': '/gluster_bricks/engine/engine', 'arbiter': 0}) => {"ansible_loop_var": "item", "changed": false, "item": {"arbiter": 0, "brick": "/gluster_bricks/engine/engine", "volname": "engine"}, "msg": "error running gluster (/usr/sbin/gluster --mode=script volume create engine replica 3 transport tcp storage1.private.net:/gluster_bricks/engine/engine storage2.private.net:/gluster_bricks/engine/engine storage3.private.net:/gluster_bricks/engine/engine force) command (rc=1): volume create: engine: failed: Staging failed on storage3.private.net.

On the volume page: all default settings. On the bricks page: JBOD / Blacklist true / storage host storage1.private.net / default lvm except the device is /dev/sda4 I really need to get this setup. The first failure was the filter error, so I edited the /etc/lvm/lvm.conf to comment out the filter line. Then without doing a clean up I reran the deployment and got the above error. Thanks in advance Brad

Engine VM FQDN will not validate.
by admin＠foundryserver.com 30 Oct '21

30 Oct '21

Hello, I am trying to install the Hosted engine using the wizard. I am NOT using the hyper converged. When I add the fqdn of vmengine1.domain.com I get the error. localhost is not a valid address. When I add the host fqdn in the advanced area it validates, if I put the vmengine1.domain.com in the the host section it validates. Facts: - I have the domain in dns, confirmed by dig to resolve to the public IP of the host. - I have the domain in hosts file confirmed by using ping and dig - I have generated a ssh key for the root user on the host and I have added it to the known hosts file. - I have logged into via ssh to all forms of addressing, so the known hosts file has been updated. localhost ecdsa-sha2-nistp256 AAAA host1 ecdsa-sha2-nistp256 AAAA host1.localhost ecdsa-sha2-nistp256 AAAA vmengine.localhost ecdsa-sha2-nistp256 AAAA host1.domain.com ecdsa-sha2-nistp256 AAAA vmengine1.domain.com ecdsa-sha2-nistp256 AAAA The reading suggests that the error doesn't mean what it says, but something about ssh not able to login to the host. I have been able to login to the host with ssh manually from the cli. Any help would be greatly appreciated. thanks Brad

Snapshot and disk size allocation
by jorgevisentini＠gmail.com 28 Oct '21

28 Oct '21

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.

Power Saving schedule, hosts not shutting down
by Maton, Brett 28 Oct '21

28 Oct '21

Hosts still not shutting down, VM's get moved from host to host by Migration initiated by system (reason load balancing) events every few hours, unfortunately there is nothing in the event logs about power management though. Any thoughts or suggestions on logs to look into? Regards, Brett
