Is it even possible to mount an LXC snapshot?
root@prox1:~# lvcreate -s --name snap vg/vm-100-disk-0

I can take as many snapshots as I need of a running Container both in the GUI and CLI, and PBS can make backups of a running LXC in snapshot mode without any issues. So why can't I clone a running LXC residing in a thin pool? I get:
"Cannot do full clones on a running container without...
Every backup of a 20 GB container (a thin-pool LV) on a PBS server in snapshot mode takes the same time, approx. 10 mins, regardless of whether it's the initial backup or the subsequent backups. OK I get that the 2nd, 3rd backups are incremental in disk-space used and that's certainly a good...
When creating LXCs in a thinpool on LVM over RAID1, I'm not sure whether or not to lay the filesystem on
* the RAID1 array before LVM comes into play,
* the logical volume just before converting it to a thinpool,
* just leave it to Proxmox to lay the fs when creating the containers...
My tests on bare metal servers show that read and write operations are a third faster with RAID 0 compared to RAID 1. The question is: Would that boost in I/O speed get reflected inside VMs and LXCs?
With the latest kernel in PVE 6.4 (5.4.114-1), is it possible or even safe to turn on the unified_cgroup_hierarchy parameter? If it is possible and safe, how to enable it (the file to enable it in and the lines to add/edit)?
This parameter is needed for per-user throttling of RAM, CPU, IO...
Is it safe to install the glibc-source package on Proxmox 6.2? i.e. won't interfere with or break the Proxmox packages?

Getting this warning / error twice each second, sending the kern.log and messages files in /var/log on the Proxmox node into over-drive. Is it signalling a potential hardware failure?

Made a silly mistake on my single public-IP machine when I ignored the requirements for installing a Let's Encrypt certificate on the host.
There are a few prerequisites to use Let’s Encrypt:
1. Port 80 of the node needs to be reachable from the internet.
2. There must be no other...
Hello Proxmox Network Gurus :-)
I need your advice. I am stuck with 1 public ip on a Proxmox host, so I am using a bridge and NAT port forwarding to a single container.
root@prox1:~# cat /etc/network/interfaces
iface vmbr0:0 inet static
Are there any differences with regard to what is being provided between the Enterprise and non-Enterprise repositories for Proxmox 3.4? Are there any advantages or pluses to having access to the Enterprise repository for v3.4? For instance, security updates, kernel updates, app...
This is the sync example given in the wiki:
root@zfs1:~# pve-zsync sync --source 100 --dest 192.168.1.2:tank/backup --verbose --maxsnap 2 --name test1 --limit 512
Couldn't find any examples for configuring a non-22 ssh port.
Also, what does "not possible to sync recursive" mean?
Never knew or heard about this switch for ext4 until now.

I've just installed PMG-5 in an openVZ container (PVE 3.4, the container template is debian stretch from openvz.org) and all seems to be working fine.
But, I am getting copious amounts of this error in the log files in /var/log/ .
