  1. [SOLVED] How to mount an LXC snapshot? [device /dev/vg/snap does not exist]

    Thanks for giving me the clue. This didn't work: lvchange -ay vg/snap This worked and prepared the snapshot for mounting: lvchange -ay -Ky vg/snap From "man lvchange" : -K|--ignoreactivationskip Ignore the "activation skip" LV flag during activation to allow LVs with the flag...
  2. backup in suspend mode seems never finished

    If your LXC is not a thin LV, I believe you only have 2 options for backups: 'Stop' mode if you can afford an extended downtime with your LXC, or 'Suspend' mode if you just want no more than a few minutes of downtime. By the way, in my case, the 'Suspend' mode backup is taking about 80% longer...
  3. [SOLVED] How to mount an LXC snapshot? [device /dev/vg/snap does not exist]

    Hi Guys, Is it even possible to mount an LXC snapshot? root@prox1:~# lvcreate -s --name snap vg/vm-100-disk-0 Logical volume "snap" created. root@prox1:~# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert cts vg twi-aotz--...
  4. 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...
  5. 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...
  6. How do i know if my lxc container is nested?

    Thanks. Does that mean what I see in the container's /dev and /proc folders are actually the host's /dev and /proc folders?
  7. How do i know if my lxc container is nested?

    Is there some sort of indicator inside the container that confirms that nesting has been enabled and is active?
  8. Single-file restore and LVM

    Which is proving very useful as it's restoring the source folder directly to the target path and the restore action is taking much less time to finish. With either proxmox-file-restore or the interactive shell, is there a workaround so that the files in the target path can be overwritten with...
  9. Single-file restore and LVM

    Ah, yes. Excellent, it works! Are there plans to support wildcards in file selections? That would be so good. root@srv:~# proxmox-file-restore extract ct/150/2021-09-21T12:54:01Z /root.pxar.didx/*.orig /root/origs/ --verbose Error: error opening '[47, 114, 111, 111, 116, 47, 42, 46, 111...
  10. PVE 7.0 BUG: kernel NULL pointer dereference, address: 00000000000000c0-PF:error_code(0x0000) - No web access no ssh

    Thanks. That has helped. The thing is, on a fresh 7.x install, there is no pve-kernel-5.11.22-3-pve in /boot/grub/grub.cfg. Is there a way to grab and just install the kernel?
  11. PVE 7.0 BUG: kernel NULL pointer dereference, address: 00000000000000c0-PF:error_code(0x0000) - No web access no ssh

    Is it possible to downgrade to pve-kernel-5.11.22-3-pve without having to choose that version manually on reboot ? I only have ssh access to the server.
  12. Proxmox VE 7.0 (beta) released!

    Is there any progress or approximate ETA on supporting user quotas in containers in PVE 7.x with cgroupv2 enabled?
  13. Single-file restore and LVM

    Hi Stefan, Does the file-restore CLI work with containers? If so, I can't figure out what should follow on this line. proxmox-file-restore list ct/150/2021-09-21T12:54:01Z I have these working variables in .bashrc: export PBS_REPOSITORY=localhost:backup1 export PBS_PASSWORD=3E...
  14. LXCs in Thinpool Over RAID1: When should I mkfs.ext4 ?

    Thanks, Stefan, for clarifying. Taking that conclusion one step further, if I increase (over-allocate) an LXC's space online through the GUI to, say, 200 GB (with, say, 50GB used up) before the thinpool's space is auto extended from a starting point of, say, 75 GB upwards, will the LXC's...
  15. 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...
  16. 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?
  17. Proxmox VE 7.0 (beta) released!

    Do you think those changes in 7.x to starting up containers to enable cgroupv2 user quotas will/could be done before 6.4 reaches EoL?
  18. Proxmox VE 7.0 (beta) released!

    If the container's systemd could be upgraded to 231 through a backport, would CentOS 7 LXCs work correctly in a cgroupv2 environment? Update: Attempting to upgrade systemd to 234 in CentOS 7 ended in tears, with several exceptions and errors. The backport utilised was...
