This is one of the reasons why I went with ZFS with replication instead of CEPH when I rebuilt the ProxMox clusters. Much as I love CEPH's fault tolerance and able to self heal on it's own without any involvement from me the performance with regular spinning 8TB 7.2K SAS HDDs just wasn't...

Do this on the VM's hardware section. Edit Network Device that is connected to the LAN bridge and check on "Disconnect" option:

I saw that command which is cool but wanted to simply replicate the live VMs over to the remote cluster and then leave the VMs in it's current state until I manually switch them over. I suggested the command qm remote-replicate for that. And then qm remote-migrate to actually migrate them...

I have few pfsense VMs running on my PVE nodes as wireguard VPN servers. Before the initial boot up make sure you "disconnect" the network interface that is connected to your LAN bridge. Pfsense will dish out DHCP and will cause IP issues on your LAN network. Once pfsense boots up manually...

Are there any further updates on replicating the VMs between clusters using ZFS? I am looking into replicating the VMs from the cluster at the data center via WAN over to corporate office. I know this can be done using ZFS send commands but hoping in more scripted or WebGUI way of doing this...

Putting them on ZFS storage will help a great deal as it will make use of ZFS snapshots. And then the backups will save the snapshots without affecting the VMs much. So give that a try. Also, definitely make sure qemu agent is installed as it will coordinate the internal snapshot of the VM...

I back up several VMs few times a day to the PBS server without much of a slowdown regardless of VM size. The storage is all ZFS with scheduled replication. If you're using CEPH yes it will slow the VMs down a bit during backups.

I too was confused by this behavior and wanted to make sure the backups a new VMs are successful and able to restore without issues. I've already have two more PBS servers as a test and all VMs were able to restore without problems. The wording is technically correct. At first I was like...

Technically under the hood a CEPH host is the same for ProxMox just with different tools installed. I actually have thought about using three beefy servers with lots of disks just for pure CEPH without ProxMox installed for performance reasons. I've had bad performance issues whenever CEPH...

I've ran into this VSS issue with Windows 10 VM which resulted in 8194 error in the windows log. Below link is the fix without running that VSSfix64.exe. Just follow steps 1 through 11. You don't need to adjust anything else. https://kb.msp360.com/backup/errors/vss-error-8194-access-denied...

I am pretty much in the same boat. I have 4 DCs. Half are physical with FSMO role on one of them and other half as VMs. I am in the process of moving the VMs from vmware to ProxMox using the offline export OVF method. All DCs are running Server 2019 with 2008 R2 domain level. Can't raise it...

This qm remote-migrate very cool to move VMs between clusters but what if I just want it to sync the VMs as cold standby? Something like qm remote-sync where it'll sync via ZFS snapshots? This way I can have a working copy as cold standby on the remote cluster in case the primary cluster...

While I was looking around on my PBS server I've noticed this: I was like oooohhhh does this mean I can go to the host WebGUI and set it to backup the host? So far nope based on the posts here. lol :) I know it's on the roadmap. So I'll look into using the CLI / Bash script for now. P.S...

I'm working on moving away from vmware that already have this functionality built-in. I'm not afraid of using command lines. Just wondering if in the future WebGUI would have some sort of monitoring built-in to ensure the scheduled replication between clusters are working properly.

I think the issue was I as trying to do mountpoints inside the container which didn't work. I wish the backup process would give some kind of a warning. If it can't be done then no worries. I just have to pay closer attention to this in the future. I was able to restore from older backups...

Looks like this happened again when I tried to restore one of my containers. I had to use older backup to get it to restore. Below are my current package versions: Header Proxmox Virtual Environment 7.2-11 Search Node 'pveit1' Hour (average) CPU usage 12.46% of 12 CPU(s) IO delay 28.91%...

I've had the same issue with some VMs not backing up which bugged me for several days until I noticed the pvescheduler service was dead on the status screen. I've tried starting it both WebGUI and CLI. I also noticed the replication also stopped working. Figured I needed to reboot the...

I know what you're going through trying to deal with VMs thats running on CEPH. I've experienced the same slowdowns or sometimes freezing during backups. This is before PBS came around. I ended up trashing the servers in favor of a different solution for now. I will get back to it when the...

Would be cool if that dark script for PVE also work on PBS.

Thanks for pointing that out. Didn't know. :)
