If I experiment with different host types (kvm64, qemu64, host) do I risk affecting the windows activation? I am building a new Windows server 2019 and am curious if I try different host types will it affect my activation license. Should I pick a specific one in this case? I do perhaps to...

I don't think rescue works with ZFS. Just before proxmox begins booting, You should see a screen that lets you pick the kernel. It times out after a few seconds so press the arrow key to stop it and pick.

Did you get anywhere, what about error messages when attempting to start? In the GUI hardware field for one of the VM's does it show for anything for hard disks? qm rescan check /etc/pve/qemu-server/

I recently installed two used supermicro servers in production, looks like they are in Legacy mode. I'm on enterprise and haven't been offered this upgrade yet. But I've been reading I might be able to switch the bios safely to UEFI mode without having to reinstall, so I will try that...

Why is the PBS community edition 5x the cost of a VE license? I'd like to support this project but at the moment the pricing is too high.

Quite a few patches/updates seem to be released. How often do you apply proxmox updates?

Sorry that its freezing, it may be a memory issue, hard to debug if its not really reproducible. You can boot proxmox and do the mem test during the boot screen.

What do the last lines in /var/log/syslog show during that time.

omg its up!! So all I had to do was wait this out?! This is scary at boot time when its your first big issue and no warnings. Especially on a clean boot. A 'please wait' would have been awesome!

ok I was able to mount in read only with no problem but as soon as I mount with write, I got a few msgs in dmesg and all zpool commands freeze while this is happening. drives are still spinning, maybe I can just wait? [dmu_objset_find] going nuts in iotop... Maybe I can wait this out! Jan 18...

Do I just need to let the import complete, how long can it take? hours? I'll ty tonight.. Should I try readonly?

So I've been doing some reading, I am certain the oom killer has caused this. For whatever reason ZFS went crazy on my crystal disk tests with virtio and crashed. I am going to limit the ARC size in hopes to prevent this. I still have not attempted to import my second mirror tank.

I'm still terrified to attempt to import second tank1 pool. I read some command of zpool import -R or something... root@pve-art:~# zpool import pool: tank1 id: 12700964996125508439 state: ONLINE status: The pool was last accessed by another system. action: The pool can be imported...

logs are pointing to : kvm invoked oom-killer How can I be out of memory, 128G.. unless the hung benchmark test went crazy on the ZFS ?

Thanks for responding, Re-tracing my steps I had a VM in windows running in IDE-mode I added a virtio driver for a 2nd drive to get the virtio-drivers recognized. I ran a crystal disk benchmark in the VM on the new drive and it caused the process to hang after a few runs. At this moment I...

I reinstalled proxmox and copied the pve-cluster (/var/lib/pve-cluster/config.db) I was able to get my main VM's going ! Thankfully I have 3 pools 1. rpool (proxmox) 2. tank0 (Fast ssd) 3. tank1 (large hhd) tank1 is causing the hang on import. At least I am back up... gotta find out...

I can't get anywhere.. I am trying to reinstall proxmox. I was able to get to install CD I mounted my zfs into an alternate directory i backed up everything on a separate drive. when IM import that second zfs it hangs again with the same errors, I am trying to see if I can tell it not to...

After doing some disk benchmarks, I started losing VM's... one by one then the entire Server rebooted. I can't believe this. Now Proxmox won't boot. "proxmox a start job is running for import zfs pools by cache" (Timeout) Then a "tainted" message. I am about to boot with the install CD and...

I have a similar issue, the writes appear every 2 seconds but very small. Are they necessary to be written so quickly? I have a new proxmox setup and two new Samsung PRO drives running zfs mirror pool for the operating system. (no vms on these drives) I've been online for about 2 weeks my...
