  2. [SOLVED] BTRFS Filesystem in LXC/LXD Container

    Hi, on a fresh install of Proxmox with BTRFS, I noticed that the containers install by default with a loop device formatted as ext4, instead of using a BTRFS subvolume, even when the disk is configured using the BTRFS storage backend. I'd like to use BTRFS directly, instead of using a loop...
  3. Permission denied - Failed to exec "/sbin/init"

    Hello, I am new to proxmox and LXCs. One of my LXCs suddenly won't boot anymore. Three others are working fine. I did some research on my own and found two possibilities: ZFS problems or a kernel update. But I'm using ext4, so maybe it's the problem of an "apt full-upgrade"? The error message...

  11. [SOLVED] LXC container fails to start without any reason

  12. [SOLVED] How to automatically mount a SMB share on an LXC

    I have an Ubuntu LXC on PVE and I want it to mount automatically after a reboot to a Samba share because doing mount -a each time sucks. So I checked the SMB/CIFS box and as I said I can access the share manually after mount -a. My guess is I should type a magic command into the /etc/fstab, but...

  15. [TUTORIAL] Bind Mount: LXC UID Mappings with multiple Containers

    Hi, While researching this I stumbled up on an older thread discussing bind mounts to Linux Containers and UID/GID mapping here. The unanswered question @John Driessen asked can't get out of my head: Normally when we think about unprivileged LXC it's ID on host = ID on guest + 100 000. But...
  16. LXC trying to start itself

    Hi, I got a strange issue, where I'm not sure how it happened, but one of the configured containers is always trying to start itself, even if it's not there. It's kind of spamming the activity log and although it's not disrupting anything, it's a bit of annoying. Could you please point me where...
  17. Recommended way to use a HBA/SAS Expander in LXC

    I have been trying the past week to move most of my VMs over to LXC since they all run Linux anyway. The only thing I'm struggling with is finding a easy solution to pass through my SAS expander or the block devices directly to the container so I can do all the mounting in there. Obviously with...

  19. [SOLVED] LXC with more cores assigned uses dramatically less CPU. Why?

    I have an interesting situation. An LXC running Power-mail-in-a-box has 4 cores assigned (with 8GB RAM and 100GB NVMe ceph pool storage). The graph below shows the following: The section from 9:32 to around 10:02 is when I only had 4 cores assigned. Before and after that time I had 12 cores...
