SSBD issues on live cluster

Hey folks,
new hardware arrived \o/
Installation as HCI was a bliss, with gluster et all.
Deploying the hosted engine also worked until it came to the very last
point: Health checks, which failed.

Re: Gluster setup
by Strahil
In /etc/hosts you first enter the IP then FQDN, and last shortname (aliases).
Fix the /etc/hosts file !

Gluster Questions
by Christian Reiss
Hey folks,
Running a 3 node HCI cluster (in testing stages) I would love to hear
your input. All nodes are exactly identical and have a local storage of
8tb in SSDs made out of a RAID6.
Gluster was setup to match this (Raid6, cluster of 256k).
There is the option of compression & dedup, coming from ZFS this is a
memory hog and kind of insane. What are your thoughts on compression &
dedup at this time?
The effective size of the compressed drive is suggested 10-fold of the
original sizes. Seems a big crazy high; any suggestions here?
Thanks for your input!
-Chris.

External VM vdsbroker parsing error
by Marcus van Dam
Hi,
I am running a two node oVirt cluster, based on the "High-Availability
oVirt-Cluster with iSCSI-Storage" document published by Linbit. Although
a older document, I am happy with the setup.
With this setup, I notice a flood of failed VM imports in the engine logs.
This setup is based on a separate Qemu VM running the oVirt-Engine.
Which seems to be the origin of the error (posted below).
Is there anything I can do to either ignore this instance and not fill
the logs, or fix the import error?
Thanks!
- Marcus

Do I need to use self hosted engine with a GlusterFs three node setup
by donagh.moran＠oracle.com
Every piece of documentation I read regarding the setup of Gluster seems to suggest using at least one of the the nodes to host the engine. Is this a requirement of can I use an engine that is deployed on a VM on another server in the same network? Any info would be much appreciated.

Gluster Network Issues....
by rob.downer＠orbitalsystems.co.uk
I have set up 3 SuperMicro's with Ovirt Node and all pretty sweet.
FQDN set up for LAN and also after setup I have enabled a second NIC with FQDN for a Gluster network.
The issue is the second ports seem to be unavailable for network access by ping or login.... if you login on root the system says that the ports are available for login on the bash shell after login and node check comes back fine.
I have IPMI set up on the systems as well for access.
am I missing something ?
I realise Gluster should be on a seperate LAN and will put it on a 10BGe network but I'm just testing.
I have the lastest stable build.
Any help would be appreciated.

Hosted-Engine wizard disappeared after cockpit idle session timeout
by wodel youchi
Hi,
I got this behavior once and I didn't tested again.
I started the hosted-engine deployment using cockpit webui, the process
went smoothly, the LocalHosttedEngine VM was created, at that time I left
the console for sometime.
When I get back the cockpit console was closed due to idle session timeout,
I reconnect, and the hosted-engine wizard had disappeared and I didn't find
a way to get it back, the only choice was to start the process again even
if the console was showing that the host was registered with a hosted
engine Manager, so I couldn't continue the deployment (the storage phase).
I had to stop the LocalHosttedEngine VM, delete it's temporary disk, then
restart the deployment again and this time I stick with cockpit webui to
get it done.
Regards.
