Yes, that's the idea behind "min_size=2" :-)

Well, my whole point in the first post is that the absolute minimum is not a scenario I would like to use. If you think it will work fine for your use case: go for it! (No sarcasm, I mean it!)

That decision is completely up to you :-) You seem to have some other equipment. I would check if a small VM or a container could be placed there - to implement the Quorum Device. On the other hand a physical third server, even if small and old, lifts some restrictions and offers some...

I am not a storage guru, sorry. But yeah, NFS is simple, old+stable and shared. A "simple" setup will create a SPOF though! For PVE I am utilizing ZFS with replication. It gives me the performance of local drives, does not introduce networking dependencies and qualifies as "shared" - as long as...

"Muss" nicht, aber plausibler Weise: ja. man chrony.conf beschreibt die Details.

Yes, I am/was keen to get some of them too. That's really a bummer :-( I wanted to put two to four OSD in each of it, the actual constrains should allow for four. Now look at https://docs.ceph.com/en/mimic/start/hardware-recommendations/#ram : 4 OSD = 4 * 3 to 5 GB = 12 ... 20 GB 1 MON = 2...

Well..., ZFS ARC does shrink if required. But it does so slowly. (Edit: ...and if it is allowed to by "zfs_arc_min" being lower than _max) Too slow to be fast enough if one VM (or any other process) requests too much memory at once. RAM is the one resource you cannot over-commit drastically...

No. That script looks fine - and I had already "Like"d it. :-) I am just a bit reluctant. While I really like Debian and I know enough to do a lot of optimization/scripting I usually hesitate to add another script/tool/mechanism/agent/cronjob/service/whatever to the vanilla (PVE-) host. It...

The PBS is local and just the storage is remote in that slow cloud? I would suspect that having a working and usable PBS with just a handful of IOPS is... impossible. Remember that lokal HDDs with ~150 IOPS are considered too slow (for large/professional use cases) and SSD storage (with some...

Just to be sure, did you see this? --> https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/ From my (possibly wrong) understanding Gluster is deprecated, at least Redhat states: https://access.redhat.com/support/policy/updates/rhs/ But even if other people do...

Yeah, you have absolutely valid points. That's why I emphasized "_my_" pov ;-)

ZFS hat its own semantic: ~# zfs create rpool/data/subvol-9999-disk-0 ~# touch /rpool/data/subvol-9999-disk-0/dummyfile ~# ls -al /rpool/data/subvol-9999-disk-0/ total 2 drwxr-xr-x 2 root root 3 Sep 19 21:06 . drwxr-xr-x 4 root root 4 Sep 19 21:06 .. -rw-r--r-- 1 root root 0 Sep 19 21:06...

I did not. My VMs got stuck. For monitoring? Sure. In this specific case "zed" man zed is probably sufficient. This is by far the simplest approach as it watches exclusively ZFS. Then there are a zillion full blown monitoring solutions out there. But pure monitoring does not solve the problem...

Einfach beide Anleitungen parallel lesen und ausführen. Das hat zumindest bei meinem kleinen Mini-PC einwandfrei funktioniert. :-) https://pve.proxmox.com/wiki/Upgrade_from_8_to_9 https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4 Huh??? Du meinst hoffentlich Trixie ;-) Und immer daran...

Did you test https://forum.proxmox.com/threads/proxmox-datacenter-manager-0-9-beta-released.171742/ ? While it may copy more data than technically required it is made for multi-cluster management...

Great! But then... your first sentence... ...was wrong. The article talks about LXC, not VMs!

"shutdown" ;-) Eigentlich ist heutzutage ja "systemd" das aktuelle Werkzeug - siehe systemctl list-timers. Aber der klassische Cron fühlt sich oft einfacher an. Falls du den PBS "irgendwann mal" tagsüber einschaltest und ungefähr weißt, wann er fertig ist und herunterfahren soll, genügt diese...

I am sure some people do. Three nodes is the absolute minimum, as official documents tell. While I do not run Ceph currently I did use it last year - in my Homelab; some findings: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/

I really appreciate your posts about testing storages, even though it is one (or two) levels above my world. But please, a bare numerical value without knowing the unit is... problematic just incomplete.

That's the curse of such physically small devices. Keep in mind that "not ideal" may mean different things; one not obvious aspect in one of my systems is this: rpool ONLINE 0 0 0 mirror-1...
