  2. Cannot do full clones on a running container without snapshots (Thin LV)

    Hi Guys 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...
  3. 20 GB Container taking 10 mins. to backup, snapshot mode

    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...
  4. How do i know if my lxc container is nested?

  5. LXCs in Thinpool Over RAID1: When should I mkfs.ext4 ?

    Hi, 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, or * the logical volume just before converting it to a thinpool, or * just leave it to Proxmox to lay the fs when creating the containers...
  6. Does RAID 0 increase I/O for VMs & Containers ?

    Hi, 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?
  7. GUI showing LVs 7% bigger size

  8. unified_cgroup_hierarchy?

    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...
  9. Can KVMs and LXCs have access to their files on the PBS?

    That would be a nice addition, don't you think? Or is this feature already available and have I just missed it?
  10. LXC 'du' size confusion

    Why would an LXC container with actual data size of 19GB and 120GB raw file show 56GB in 'du'? Using hdds on Proxmox 6.3.
  11. Is it safe to install glibc?

    Is it safe to install the glibc-source package on Proxmox 6.2? i.e. won't interfere with or break the Proxmox packages? root@srv5:~# apt show glibc-source Package: glibc-source Version: 2.28-10 Priority: optional Section: devel Source: glibc Maintainer: GNU Libc Maintainers...

  13. How to remove host's LE cert and release port 80?

    Hi, 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...
  14. IPtables Rules for NAT reflection / loopback

    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 ........... auto vmbr0:0 iface vmbr0:0 inet static address netmask...

    This is the sync example given in the wiki: root@zfs1:~# pve-zsync sync --source 100 --dest --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?
