Thanks for your answer.
Yes, now you can do it via backup and restore:
take a backup of the engine with engine-backup and restore it on a new
hosted-engine VM on a new storage domain with:
hosted-engine --deploy --restore-from-file=mybackup.tar.gz
That is great news. Just to clear things up completely:
- This backup command is sufficient ? No further switches ?
"engine-backup --mode=backup --file=[EngineBackupFile] --log=[LogFILE]"
- Do I need to place the node to which I want to deploy engine into maintenance
before doing the backup? This is referred in the stated documentation as:
"If a hosted-engine host is carrying a virtual load at the time of backup [...]
then a host [...] cannot be used to deploy a restored self-hosted engine."
This is still true? If yes: all other precautions apply from that documentation?
- before creating the new engine on the new storage, the old engine need to be
un-deployed on all engine-HA hosts. I am unable to find information about this
issue. Just un-deploy via web ui?
- I want to deploy on a gluster volume that has been automatically created by the
Node setup. The file /etc/gluster/glusterd.vol does not carry
"option rpc-auth-allow-insecure on" which is mentioned in the documentation.
Do I need to follow the instructions for gluster, or are settings already sufficiently
set by the automatic gluster deployment done by oVirt Node setup? I already
have some VM images running on that gluster storage anyway.
Thanks for your help.
