On saturday the fourth 4TB SSD arrived and I made a fresh install on a ZFS RAID10. Although the effect is not as good as I was hoping the system is running quite ok and working on the Win11 VMs is acceptable. IO delay is now below 1% most of the time with some peaks up to 5%. Seems ok for now...

...the great aspects of Linux! For an experiment or to write a blog article; for a productive setup *I* would never do that. (( I would stick with ZFS, of course. If there is no redundancy possible I would make sure that I run Backups with a higher frequency than usual - depending on the "Plan...

Thanks. Think about making a raid on top of a raid, because it safed me in the past because i made a configuration mistake... A RAID 1(RAID 6(RAID 1)). There are two things which I think of: 1. Using ZFS on top of ZFS 2. Using an LVM Mirror on top of ZFS. What do you think?

Restart not needed

...proxmox-backup-client, but I am not sure how to recover from the backups. I understood boot from proxmox ISO USB into recovery mode. Mount the zfs pool (subvolume of host root into /mnt for example) and then issue the proxmox-backup-client restore command into /mnt?? More detailed guidance...

Thanks, Is a restart necessary? root@painelvip6:~# zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT data 1.80T 748G 1.07T - - 27% 40% 1.00x ONLINE - root@painelvip6:~# zfs set direct=disabled data

zfs set direct=disabled POOLHERE Also see linked thread above.

Could you describe the procedure?

Only fix for me was disabling direct on zfs, not had a problem since.

you need to either use 2MB pages or 1GB pages not mox like your trying to do. huge pages will only be used on VMs you have set to use huge pages with else they will use standard 4k pages. huge page allocation also needs to take into account numa so you will have a huge page slab per numa node...

...wenn viel geschrieben wird oder es reicht das der pbs down ode rnetzwerk kurz down geht (was auch im firmenumfeld passieren kann). aber als fallback klingt es gut. wenn mein vm zb ein zfs vol ist, nimmt er dann automatisch dieses wenn nix angegeben wird für das fleecing? danke für deine...

...einbauen, dann forciert Du das nicht. Storage sollte wie in der Dokumentation beschrieben thin provisioning und sparse unterstützen. Kannst Du bei der Konfiguration angeben. Am besten mit dedizierter physischen Platte, es geht aber natürlich auch dein lokales lvm-thin Storage oder ZFS etc.pp..

...die Situation kommen, wenn vms mit größen Datenbanken gesichert werden sollen.. Wie sieht es mit dem auto storage vom fleecing aus, wird dann das gleiche zfs volume / nfs storage benutzt wie von der vm oder muss man es explizit festlegen, damit es auf keinen fall auf die root platten geht.

...above commands keep the current (Debian) kernel and install a minimal setof required packages. You can install the Proxmox default kernel with ZFS support by using: apt update apt install proxmox-default-kernel This is not the case - the proxmox kernel is installed and configured regardless...

New to proxmox and ZFS here. I currently have two proxmox nodes pmnode0 and pmnode1 both with zfs root filesystems. I had a power loss event yesterday on pmnode0 while proxmox was actively in the process of shutting down. I went to reboot and proxmox just hangs, I boot into proxmox ISO exit...
