  1. Snapshot removal "jams" the VM

    Hello, I'm running Jenkins inside a VM ran on a Proxmox VE 7.1.8. The issue is that when I delete a snapshot, the VM enters a locked state, which in turn stops it from responding to requests. I don't know if this is the normal behavior and, if it is, why is it running this way? In my opinion, a...

  5. [TUTORIAL] Proxmox Ceph Mirroring - Snapshot Mode

  7. Will I screw anything up if I create my OWN zfs snapshots of lxc/qm disks which I have on zfs?

    I keep my LXC container and QM VM disks on a ZFS filesystem. I don't know much about how PVE manages the ZFS snapshots associated with a given container/vm, but I do see in my filesystem that it does have various snapshots which it creates for migrations etc: root@node1:~# zfs list -r -t...

    I've done lots of searching and haven't seen this question answered, but I apologize in advance if I missed something. Does Proxmox Backup Server backup manually created snapshots of a VM? Can the snapshots be restored without restoring the entire VM? Thanks in advance!
