if you have no any dedicated storage, it's possible to use literally any PC with nfs\smb\external drive, windows share also.

going fine after reboot. -
Disk migration queue
Maybe i'm wrong a bit, but it's no any queue for disk migration? I can run 5-10 at same time, but it will likely crash and cancel migration.
Usage: move vm disks inside pool from one storage to another. Now i need to move 3 at once, wait till done, move next.

RE: VM’s Slow booting
Ubuntu 20-22 boot is slow by design. It may take 1-2min.
Debian or any rhel boot in 20sec. -
RE: NBD setup - No such item
that log appear again, without any actions from my side.

RE: Rolling Pool Update - host took too long to restart
got that issue too. Sometimes server restart takes longer than usual, so rolling is canceled by timeout.
Why it's so long? i dunno. Maybe some startup checks. Can't restart production to notice any difference.Is the timeout really requried?

RE: NBD setup - No such item
@florent also it works too good.
i don' used advanced mode for CR backup, so NBD is disabled for job.
but task is working with nbd)

RE: NBD setup - No such item
@florent lets a brief summary.
nbd work only via management interface. If nbd enabled on any another interface and specified as pool backup interface, it don't work (the issue with blocked packets at iptables). That was a main reason of my problem.
For now i made it work at all my pools. Max single thread speed increased 80-90 > 140-150. At usual backup task (when daily delta very small) it show same 10-40Mb, because it done too fast. Average task time decreased fo about twice.

RE: NBD setup - No such item
next weird thing.
i enabled NBD on all manage interfaces at all pools.
it working with CR backup, but shouldn't, at least because it no option to enable NBD.
it working with half of other delta backup tasks, but not for all. Main backup is still without nbd.
only idea, it probably because of 1 small pool with few vm, where i forget to enable NBD. so 1 VM without nbd, force it to work in usual mode?

RE: NBD setup - No such item
once again i configured it on fresh, test cluster, and it working.
so it some problem with iptables on production. But it default, same 8.2.1 clean installation.
Both this hosts have only 1 connected link, so it both backup and management.
On prod i try empty default backup network, or NBD link network - no effect. So maybe it still going through managemnt link without NBD?aaaaand enabled NBD on Mng link - now it working. SO yes, it ignore specified backup link.
Or this option didn't work, because NBD now enabled only on Mng link, so it can't go through backup link. -
RE: load balance, density. Doesnt seem to be working
probably, documentation not very correct.

RE: Managing 1000+ VMs in 3 pools
@rodito said in Managing 1000+ VMs in 3 pools:
@Tristis-Oris when you look for project specific VMs do you know all of the tagging or you have some sort of master list.
well, yes, i know everything about my infrastructure. But at that case folders better to find something you don't remember.
@olivierlambert without folders implementation, global tags list possible to solve some similar problems maybe.

RE: Managing 1000+ VMs in 3 pools
at XO no need to use folders\tags like "windows" "linux", because it already can be found with simple query. I'm fine to manage hundreds vms, see no problem to do it with 1k.

RE: Workflow Tool
@john-c dunno about how that script should work, but you can execute anything with
ansible.builtin.shell

RE: NBD connection during backup

RE: One-time backup of VM
a case for this: have a lot old, disabled vms with some archive data\projects. Probably they will never be used again, but who knows. So i create 1 full backup, but when yet one vm go to archive, i need to run that task for all vms.
