Hello,

I've read various posts[1] on this list, but I must confess that I am
still not entirely clear on the process for moving a hosted engine to a
new storage domain (in my case I want to move from an existing NFS
server to a new iSCSI target). Some of what i've read make me slightly
concerned it's a risky operation and in my situation I am just
prototyping and retaining the existing engine will be saving some time
rather than mission critical.

Is anyone able to outline the steps to me?

The flow is:
1. set hosted-engine global maintenance mode
2. choose one of the existing hosts and set it to maintenance mode from the engine
3. take a backup of your current engine with engine-backup
4. copy the backup file to your host
5. on the host in maintenance mode run:
    hosted-engine --deploy --restore-from-file=backup.tar.gz
6. at the end you will have a new engine VM created from your backup file, the previous hosted-engine storage domain will be still visible (although renamed) so that you can eventually migrate additional VMs created there by mistake; at the end you can remove it
7. one host at at time, set other hosted-engine hosts to maintenance mode and choose reinstall being sure to choose to deploy hosted-engine
that's all.
 

thanks,

Dan
