ZFS has sync=disabled per dataset, so you can always do write back if you feel lucky.

You have write cache. It is called either RAM for async writes or slog & RAM for sync writes.

No, you can't. The performance will be lower, except very few cases (high cache hit rate after warmup, highly compressible data and use ZFS compression). As @fabian already told you, the writes don't matter if you use a SSD slog. They are either async and get written to disk on txg commits or...

It is always better to use expensive hardware than cheap hardware. What was the question?

Oh, I didn't notice the Z3. With ZFS-type RAID you get the speed of the single slowest disk in the pool. It is all about capacity & redundance, not performance.

Try an iostat -kxz 1 during these operations. Maybe a drive is gone bad?

I cannot find the memory related settings. You say ZFS ARC is limited to 32GB, but ZFS takes more than that (e.g. write buffers). You say 9 VMs, but no information about they memory allocation. No word for containers either. The reason I'm interested in this is because I've hit the same issue...

Thank you!

It depends on how your monitoring tool interprets stuff. You need to post at least the "free -m" output and maybe "ps uaxwww | grep kvm" output.

I don't think you need to set anything to have a fair scheduling between tasks. You set when you need one thing to get more CPU time than the others. For example, you have 3 VMs. First one has 1000, the others have 500. So there is a total of 2000, 50% is going to the first VM, 25% to 2nd VM...

Looks like sencha fixed it. Google "EXTJS-19223".

username is "root" and the password is what you have set-up in the install GUI

@dfgas units are relative, as @dcsapak pasted in docs. You cannot find "how many units my system is capable of doing" because there is no such thing.

Scrolling works on Safari, too. Also keeping the arrows clicked does scrolling, no need to click multiple times.

Which brings back the question on why do we need it inside PVE. Are there any PVE specific changes that Promox does to the main repository? I understand that you guys want to provide "stable" packages but that's the purpose of pvetest repository, as far as I know.

Any news on this? I've seen a new kernel released today, but no 0.6.5.8. The list of fixes in 0.6.5.8 is pretty big, so the update can be useful.

Again, it doesn't matter what freq/cache say. The execution speed is the same.

I assume you do cpus=0;2;4;6

I don't think it matters what it is shown there.

How do you think Proxmox will be able to resize your partitions & filesystem? By magically connecting with a hidden SSH key and apply fdisk and resize2fs? https://pve.proxmox.com/wiki/Resize_disks
