I am handling this different because I find all other options (even with pbs) too complicated for my usecase at home. Have installed pve on a small SSD. From time to time I just shut the host down and did it over to another SSD. Since my config is pretty static another config backup is rarely...

Try another adapter or disk/SSD There are tons of chips out there and some just don't play nicely with all combinations of gear. It also may just have a defect

No worries. It is easy to overlook the most Fundamental things, because we assume they are so basic that they just work. ;)

Does it actually sync with 1Gbit? 11.5 mb also could be an issue in cabeling and a 100Mbit connection

Might be a Problem with the adapter or the SSD. Older gear (like the r610) also sometimes have issue with boot from USB. Have you upgraded the BIOS with latest version?

Your tests do not reflect any real life scenario nor do they show a significant difference, due to the tool used and the limit time of testing / working set size. Crystaldiskmark is a consumer utility in my eyes and the results mean nothing. I disagree. Raid 5 also can be used for performance...

According to these two pages they both use the same vcore which ultimately is responsible for power consumption along with the clock: https://www.pc-erfahrung.de/fileadmin/php-skripte/cpu_tabelle_info.php?ID=2313 https://www.pc-erfahrung.de/fileadmin/php-skripte/cpu_tabelle_info.php?ID=2320...

True and again this depends in the workload/usage. In my case due to the high amount of writes (backups, ZFS) I doubt that the SSDs will stand up to the job for a long time. My HDDs got replaced after a runtime of up to 9years (remember, home usage) which is also something to be considered if we...

Come on ;) you never would use just one HDD - you know that. Also capacity is not everything - the IO and potential recovery speeds, density (space in the case) might also be important. so one 22TB drive is not exactly a good example. As said "capacity is limited" - just wanted to provide a...

Depends on the drivetype but can easily double. Especially 3,5" HDDs with 7200 rpm can pull significant power. That is the reason why I have decided to use 2,5" mobile HDDs (using WD Black since 6 years pretty successfully) - of course their capacity is limited in comparison to their larger...

That is exactly my point. Of course it is noticeable on paper. We talk about 500mhz per core less. That is 20+ %. However on my usage profile it does not make a difference. I am running 18 VMs with 1-4 vCPUs, mainly Linux but one Windows guest. On that one i can notice a difference when applying...

That is the virtual disk approach (zvol) Depends on what you want to do. You can expose the zfs as a file share from the host via NFS or SMB. Depending on your usecase this is clever, or not... But you can't write directly into the hosts zfs filesystem. You need the access /abstraction layer...

Usually i am a big advocate for high clock speed per core. In your case (single socket) I'd prefer more cores / threads as I am convinced that this reduces the scheduling overhead of the hypervisor. My finding also was that for home and lab use na individual clockspeed per core also is not so...

in which case I don't have an answer for your observation. Except the limit is not correctly honored (had this once...).

Are you using ZFS? The ARC usage does not show up in the UI, hence you might have less RAM available than it is obvious.

I think this will only buy the author of this thread some time. If it is too much, it is too much. If the swap is at 100% already then I think there is not much to do other than increase resources OR reduce load.

PVE allows you to clone VMs from within the UI. Cloning disks involves CLI operations. Step 1: clone the content of the disk Step 2: edit the corresponding PVE-VM config in /etc/pve/qemu-server Step 1 I thought is outlined in the provided link, but I was wrong. The concept of a "clone" was...

not sure if this is the desired state ;) @tonycav As far as I understand you want to create a backup of your M2 based contents, that can be read elsewhere. Tell us more about your configuration. What is on that M2 (Filesystem, setup) because this also leads to certain options? Are you running...

It was a try. ;) The symptom you describe sounded exactly what I was experiencing back at the time when I was booting from USB thumb drives. At some time these went RO. The system worked a long time until it ran out of memory. Then the UI stopped working and SSH + reboot was my only way to get...

This is odd. Someone from the PVE team should have a look into this. I can't judge nor do I know all the changes that habben underneath. @fabian for a headsup.
