Alas, I'm very sorry about this. Can't reproduce this. Then let us wait for other participants who can report their success/failure.

Well, I see...then restart the whole machine at next opportunity. I set up the new pve, patched everthing, restarted both services - same as at your site: no zstd. Then I rebooted the new baby and there it is. Only the hell knows why I hadn't to do something like this at the testing machine the...

Did all the patches apply cleanly? Are services pveproxy and pvedaemon restarted (as done so in my script)? I'll setup a new pve server today and re-check this to ensure that I haven't missed something while testing...

Have you closed and re-opened your browser (or cleared browser cache etc)?

ZSTD done. Happy testing :) To activate use my shell script or patch yourself. To use zstd you have to disable compress:/pigz: etc and to set zstd: in vzdump.conf - same as with pigz: 1 means half-of-your-cpu's, >1 #of cpu's. This is a nice template for those who want to implement their...

Today I played something around this task, patched some perl files - and voila! - backup w/ zstd is working so far. This was an easy task. The first thing is that debian's zstd (in stretch) is to old (missing thread parameter), so I compiled and used the latest version v1.3.2 for this. The last...

Stimmt, so kann man es auch machen. Ich bin halt der Konsolen-Mensch :) Und guter Hinweis für die, die diesen Thread noch lesen werden, dass man den Controller latürnich umstellen sollte.

Moin! Ich hatte das auf meinen Windows-VMs so gelöst, dass ich eine zweite (winzige) HDD als Virtio SCSI angelegt habe, Windows gestartet, Treiber aus dem Virtio-Paket installiert, VM runterfahren, zweite HDD "ausbauen" und zu guter Letzt in der .conf das Storage abgeändert: scsi0...

Can confirm that Fedora (upgraded from v24 to) v26 is working stable for at least 12 hours now. This a an asterisk/hylafax container and it works as before without any issues (yet).

I'm impatient - and it's always a good idea to create and keep backups, especially for experiments :) Changed the mentioned line in /usr/share/perl5/PVE/LXC/Setup/Fedora.pm , restarted the "dead" (upgraded) container/Fedora v26 and voila, it starts and is working as if nothing other had...

Ah, these are great news. Will try and report when system comes to end of work today. Thank you for investigating into this!

Sure. They were # dnf upgrade --refresh # dnf install dnf-plugin-system-upgrade # dnf system-upgrade download --refresh --releasever=26 # dnf system-upgrade reboot Same for v24->v25 with the appropriate releasever which worked like a charm.

Upgrading from v24 to v25 works flawlessy, but neither from v25 to v26 nor from v24 to v26. As decribed in https://fedoraproject.org/wiki/DNF_system_upgrade the last step is a "dnf system-upgrade reboot" in which it installs all new packages. I can see the progress by entering the container (pct...

Ich habe keine Benchmarks gefahren, sondern nur auf die "gefühlte Wuppdizität" geachtet. Meine Proxmoxen sind aber auch "nur" Single-Hosts im Raid1, bzw. 5, mit überwiegend LXCs und wenigen, meist nicht produktiven Linux- und Windows-KVMs. Bei den LXCs spielt es ja eh keine Rolle, aber bei den...

Oh, tatsächlich. Da habe ich wohl schon länger keine neue KVM angelegt ;) Ja, SCSI mit VirtIO-SCSI ist "jetzt" Standard. Aber was hast Du denn jetzt in den "lahmenden" KVMs eingestellt? VirtIO oder SCSI? Denn in #3 schreibst Du ja, Du hättest sie als VirtIO erstellt. Insofern würde ich sie...

...aber ist es nicht vielleicht so, dass man die Disk als SCSI festlegt und in den Optionen einstellt, welcher SCSI-Controller benutzt werden soll? Ich benutze auch gerne VirtIO; unter Linux auch kein Problem, nur unter Windows ist es eher "gemütlich". Aber da ich nur selten Windows nutze, ist...

Interessant, werde ich auch einmal ausprobieren. Was Du suchst, dürfte unter "Optionen/SCSI Controller Type" sein...

The compression tool zstd/pzstd https://github.com/facebook/zstd/tree/v1.1.0/contrib/pzstd came to my attention when I read this article https://blog.fefe.de/?ts=a90c6783 Did a quick test and was quite impressed by its speed. Results added to my table above.

...added, see table above. As my table grows it may need reformatting. Are there details that were not of interest and can be removed? ie times of user/sys and decompression tests?

I vote for lrzip as a further option for backup jobs. More choices makes more flexible ;) In my opinion gzip (pigz) for fast dumps with good compression and lrzip for slow(er) dumps with better compression, if size matters (ie for archiving purposes).
