How is that relevant to the original Question ? You cannot have ZFS Module working in an LXC Container, at least not in an unprivileged one. Not sure if your Remark is applicable to a privileged LXC Container or if you had a KVM Virtual Machine. For an unprivileged Container the Solution...

I don't think it's possible. After all the -args Parameter is there for what is NOT implemented by Proxmox VE [yet] and since it feeds directly into QEMU Command Line, I believe you must use a Full Path. But why do you want to leave it attached ? My Usage at least is as a temporary LiveUSB...

Yeah, a very stupid one you could say :(. Weird that I didn't notice it until now o_O . Yet another Case of the Problem being between the Chair and the Screen. Sorry about that :(. I would have guessed that since the default none Cache Options for the Virtual Disk were used (writes ARE cached...

@fabian: spotted the Issue, almost by coincidence, while cleaning up /etc/fstab File. There was a sync Mount Option set for the / Filesystem in /etc/fstab :rolleyes: . Not sure why I did that some Time ago ... So essentially every single write would be forced to be written immediately to Disk...

For reference the same base Load on VM 156 APTCacherNG which is fast

Base Load on VM 151 MirrorNAS using atop

OK I'll stop it. Anyways the load is Peanuts I don't think it will make any difference.

@fabian: atop as you requested (fio still running)

iothread shouldn't matter and discard being disabled on the Fast VM (156 APTCacherNG) is even more weirder (it should be slower not faster if anything). I guess it doesn't make too much of a difference at this speed and probably only relevant for TRIM Operations.

htop (while fio Benchmark is running VERY SLOWLY) since I have it installed it already. I'll try to install atop as well ...

Do I need to stop the fio benchmarking ? It's doing 1K at Queue Depth 1 now (4th Test only) ...

Also the Load on the Guest 151 only If I were to take a blind Stab at it, I'd guess that only 10% of the CPU Power is actually being allocated. Not sure how that causes the Performance of the Storage to drop THIS much though. It's weird because from LiveUSB + chroot it worked fine, so there...

Not really. I mean right now the entire Server load as seen from the Host is very low and most of it it's caused by running fio right now. Everything else is pretty much Idle.

The Virtual Machine 151 MirrorNAS was left unbootable because I interrupted an apt dist-upgrade and that left either the Kernel or Initramfs in a bad State (probably due to a half-compiled ZFS DKMS Module). I basically did a rescue of that broken VM using a Virtual USB Pendrive (Debian 13...

So @fabian First results are in for the Normal / Fast VM (156 - APTCacherNG). Now I'm recovering the other one from a Chroot and it's MUCH faster already compared to when booted from the Virtual Disk (I booted from a Virtual USB Pendrive).
