High Disk I/O / SSD Disk Corruption / VM corruption

[Fasterski09]

Hi There,

I have switched over to PX from Hyper V. I'm running two old servers. I love the feature set on PX and management though web browser / backups etc.

Only thing makes me want to switch back is performance of disk I/O. I have been running 4-5 VM of the same SSD in the past. In PX I can manage to only run 3. If I run any more the whole thing is unusable performance wise and it lead to my VM loosing boot disk (corrupted disk image with OS). This is both Wndows and Linux. I have also had my older SSD (it was the newest of SSD I'm still using, it quick with SMART errors during host boot)
Now a friend of mine had lost NVME (WD Back ) after running it in PX (previously ran Hyper V for years). That kinda makes me think to switch back to hyper-v which is not what I want to do.
Has anyone seen this? I also generally see that PX is not as efficient running the work load as HyperV was . That being on old hardware and I have not installed new VM but rather inverted them from HyperV.

Only with non-enterprise SSDs.

If you compare Hyper-V with windows guests with Proxmox VE running windows guest you'll probably be right. Hyper-V is the hypervisor for running windows. Programmed by the guys that do the hypervisor and the guest os, so if this would not be the fastest solution ... I don't know which would be. Whereare Hyper-V is very good at virtualizing windows, it is VERY VERY VERY BAD in running anthing but windows.

ZFS or ext4 setup ?

Drive shows ZFS partition. Maybe this is the issue.

Im running just consumer drives. This is home setup so windows vms need to stay. BlueIris, Windows 11/ Windows 10 desktop. Showstopper seems to be the disk corruption.

What I'm seeing here is not to use ZFS and use enterprise SSD.

Not and but or: use ZFS and enterprise drives, or don't use ZFS and use any drive you like. Please note that you won't notice corruption without ZFS (or similar filesystems with check-sums) until it is too late. Always make backups on multiple media in multiple locations.
