@psafont
is it safe to remove it on production pool?
whenever the SDN controller is turned on.
so, i can do something on new host, before joining into pool to generate this cert?

RE: What metadata restore really do?
i tried https://docs.xenserver.com/en-us/xenserver/8/dr/backup.html#back-up-single-host-installations but, "command not found".
At this time, the meta restore works perfectly. I got all my VMs back, but
- since I don't believe in success, I didn't shut down the unavailable slave host, where the VMs was still running.
- After restoring on a new master, all the VMs were also running.
- except for IP conflicts, in that case I had double VDI usage!
- The old server was shut down ASAP, but some VDIs were still corrupted anyway.
This wasn't a critical issue, but after EMERGENCY restoration, I expected that the host would be in emergency mode and the VMs would be halted.

And next problem. How to restore info about VMs?
2nd affected pool https://xcp-ng.org/forum/post/95369 lost master, all VMs now running on slave which i can't connect.
If setup new host and reconnect it to SR, i only can get a VDI, not VM itself. -

fresh xen install, retore metadata, everything looks fine, but i can't join any new hosts into this pool.

ok, 3 hosts fresh install, joined into pool, restore metadata - i got pool with 1 host and others 2 removed from XO.
2nd host unavailable, as i see it got same IP as 1st.
3rd host - nothing happens.

i add 2nd host with his "old" ip to XO. But can't connect and can't remove. Probably, IP change happens at this time.

Only way i found to remove it - disable, change ip to not existed, tried to connect, remove works after error.
That looks like bloody mess. No host mapping, random results, pool is blocked from any new hosts in future.
