You're right, when I set Crystal Disk to 32GB it is freezing up the VM again. Ok, so it sounds like you might be saying I might be able to solve this by going into the BIOS and "re-enable the Disk's write cache" ?

Thanks again for help @PwrBank and @_gabriel For anyone that finds this forum. I completely reinstalled the Proxmox OS, migrated the Windows Server 2022 VM back to it and started to rerun it and was still having the freezing up issue. Not as bad as before, but it was still happening during a...

I moved the original Windows Server 2022 VM to another node on a completely different cluster, and it did not cause the freezing up when doing a crystal disk read/write test. So I am concluding that the proxmox OS must be causing the problem in the original configuration. I wish I could...

Great ideas PwrBank! Thanks! I should be able to set up a Windows 11 VM fairly fast and see if it has the same problem, that will really tell me where to focus, VM or hardware. Thanks again!

You may be right. The reason I always always set up proxmox using zfs is because then I can use the replicate feature. And the other methods didn't allow replication, or at least that was the case 5 years ago when I was first learning proxmox. The only other idea I've had is to make a hardware...

The ZFS pool originally had 5 x WD Blue SSDs: WDS100T3B0A-00AXR0 I replaced 2 of them with 2 x WD Red SSDs: WDS100T1R0A I've googled them and I don't see anything about them having QLC flash memory, but I can't tell for sure, it's too confusing. I guess I could try putting in 2 x Kingston...

Ok, I set the Cache to Default None and rebooted the VM. Support for the DB program said they don't have this problem with other customers using virtual machines with even slower drives so something must be wrong, he suggested I do a disk read/write speed test with crystal disk. So I...

Thanks _gabriel! When you say "You can move within guest backup to a dedicated drive." are you saying add another SSD to the server and do a passthru of that drive to the VM? or am I misunderstanding? Support for the program called me and actually suggested disabling "balloning device" for the...

Awesome ideas, thanks _gabriel and PwrBank. I checked the Windows's Volume scheduled Shadow Copies and the times were 7am and 12pm so it isn't that, but good idea because I hadn't looked there before. PwrBank, you were right. They don't have SQL installed, but there is a custom program on...

I am stumped here. I have a VM that is running windows server 2022. The proxmox server became 100% full about a month ago while doing a local backup. That caused proxmox to become unresponsive and the VM got corrupted and I had to delete the VM and all the local backups to free up space and...

I was having this problem with my Windows Server 2022 VM during the backups to the Proxmox Backup Server. Inside the VM, programs would freeze up and become non-responsive until the backup completed. I tried limiting the hard drive speed of the VM, limiting the network bandwidth to the PBS...

AWESOME! setting the CPU type to HOST solved this for me too!!! THANKS!

For sure! Here it is: bios: ovmf boot: order=scsi0;ide0;net0 cores: 8 cpu: x86-64-v2-AES efidisk0: local-zfs:vm-105-disk-3,efitype=4m,pre-enrolled-keys=1,size=1M ide0: local:iso/virtio-win-0.1.240.iso,media=cdrom,size=612812K machine: pc-q35-8.1 memory: 12288 meta...

Hi all, I have a Windows 11 VM, it crashed on the weekend and was going to automatic windows recovery on every reboot. I restored a backup from Friday, but it still goes to the windows recovery options (none of which fix anything of course). I entered cmd and used diskpart and realized that...

Thanks again for your help with this Dunuin. This made a huge difference. I did what we discussed above and the garbage collection speed has significantly improved. What was going to take weeks is now able to finish in a day!

Once again, thanks so much for the reply! Unfortunately the datastore is 95% full. If I connect an external HDD and create a new datastore in the GUI, is it then possible to move the backup data to the new datastore and then back to get the metadata to use the special SSDs? I see the...

Fantastic help! thanks Dunuin! I added 2 SSDs and it was really easy to add them to my existing pool, I ran the command: zpool add sync-datastore special mirror ata-KINGSTON_SUV400S37120G_82B9J921JH86GG ata-KINGSTON_SUV400S37120G_HK78BH3GKDKFHK and it was done. And then running: zpool list...

Thanks Dunuin for the reply. Yes, I am using 3 x 4 TB (WD RED) HDDs. There is no way I would invest another $2000 into the offsite backup server since it is just an offsite backup of the onsite backup server. I wish the remote sync and remove vanished option would work without having to run a...

I have a proxmox backup server off site that does a remote sync of an important datastore. I realized that the "remove vanished" option is not deleting stuff to mirror the remote important datastore so I scheduled the garbage collection but it ran through about 30% and has slowed to a crawl now...

yes, adding a firewall rule to only forward port 8007 for my static IP should be the way to go. Unfortunately my firewall doesn't have that option so I have to replace the firewall. I was just wondering if I was way off base by suggesting the GUI and the Remote Sync use different ports...
