Hello.. We have a proxmox cluster that moved sites, and cannot move the old subnet to the new site. So far, I've done the following: - Brought up the cluster on a private network not connected to the (new) site network - Let ceph settle - Followed online tutorials to change the proxmox cluster...

Hello.. I am upgrading a standalone server from proxmox 7.4 to 8. I followed the instructions and pve7to8 reported no issues. I've done multiple upgrades from 7 to 8 at work, but this is for a home system, and it's the first time it failed. After the reboot, the OS failed importing rpool...

Hello, I have a monitor node in our cluster that had an ungraceful reboot. After the node came up, the monitor could not join the cluster. After some retries I destroyed the monitor (from the GUI) and recreated it, but still could not join the cluster. I waited about a day "just in case" the...

Hello, I have a problem when backing up to a ceph cluster of spinning disks. I have a cluster of 27 server-class nodes with 60 OSDs on a 10gig network. If I backup ~10 VM/CTs it works fine. Upping that number to ~20 the backup grinds to a halt (write bandwidth in the KB/s range) but...

Hello Proxmox, I deleted 2 VMs from our cluster (that had backup jobs on them). Subsequent backup jobs fail on those VMs with "no log available", even though those VMs are not listed in the backup job. I'm getting an email from every single host in my cluster. How can I remove those VMs IDs...

Hello, I would like to enable influx data gathering for ceph. The ceph documentation that I found have instructions on how to enable it, but not how to install it; I can only assume that it installs by default. However, when I try to enable the influx ceph module in a Proxmox cluster, I get...

Hi there. We have 2 Proxmox clusters. I updated packages on one cluster with no problems. Then I started updating packages on the 2nd cluster, and after I upgraded the 1st node, the whole cluster went berserk. Initially, some of the nodes appeared up, some down, and some with a "?", even...

Hello... I did a package upgrade yesterday 2/6/22 (including kernel update to 5.13.19-4-pve) and it's consistently hanging about 20-30 minutes after boot. Symptoms include: - unresponsive console, does not respond to Ctrl-Alt-Del or ACPI Shutdown. - "qm list" hanging. Some VMs hanging. LXC...

Hello Proxmox, I would like to request a feature which is very useful in large clusters. We have a cluster with 33 nodes and way too many containers to count by hand (about 100). In the Server View, nodes are sorted by hostname, while in the Pool View containers and VMs are listed by VM/CT...

Hello, I have some LXC containers with docker running inside them. Those work well with root-on-ext4, with the required changes in the .conf files. When I do the same on root-on-zfs, I get the following messages in the console: overlayfs: upper fs does not support RENAME_WHITEOUT. overlayfs...

I have a cluster with all nodes on ext4 root. I would like to add a few (new) nodes with zfs raid1 root. I found out that there are some issues, and I would like to know what's the best way to proceed: - The local-lvm storage shows up with a "?" on the machine with zfs root, which is...

Hello, I am planning on using sanoid/syncoid or something similar to perform snapshots and backups of my zfs pool(s). I understand that I can add packages and/or do whatever I need in the host debian environment, but I was wondering if I can do the same inside an lxc container with the host...

Hello, I am in the process of upgrading our cluster to Proxmox 7, and came across the following: We have locally edited /etc/systemd/timesyncd.conf to use a local NTP server, since our firewall does not allow external NTP connections. After upgrading to Proxmox 7, the above conf file edits are...

Upgraded to Proxmox 7, installed has no problems (well, pending issue https://forum.proxmox.com/threads/unknown-video-mode-on-fresh-proxmox-7-install.92623/#post-403828, but that's a different story). We are running LXC containers with docker and gitlab-runner inside them. I modified the...

(for @t.lamprecht) Installed Proxmox 7 on two separate machines (one Haswell-based server platform [upgrade], and the one Broadwell-based server platform [new install]), both machines connected to a Raritan KVM with VGA dongle. Install was uneventful in both instances, boot up sequence shows...

Hello, I am trying to clone a container that has a mp0 mount point, but I'm getting an error "unable to clone mount point 'mp0' (type bind) (500)". Of course I can remove the mount, clone, and then re-add it, but it gets cumbersome after a while. Any particular reason why it is not allowed...

I've set up my cluster to do weekly backups and also set up backup retention to keep weekly 3 and keep monthly 3. However, /etc/pve/vzdump.cron does not have any entries for --prune-backups, as I would expect, and in fact the backups are not trimmed. How can I set proxmox to trim backups...

Hello, yesterday I just upgraded packages and noticed that docker in my LXC containers stopped working. I found out that now /proc/sys is now mounted read-only inside the container, while previously it was mounted read-write. The errors I got in the container's syslog are: Feb 9 16:38:11...

Hello... I have a Proxmox cluster with about 20 nodes. I am running Ceph on it, but I only have OSDs on 4 nodes. I have, however, installed Ceph on all nodes. Currently (sadly) I am not using a cluster network, so all the Ceph balancing traffic goes to the public network. I'd like to add a...

I was wondering if it's possible to mount a cephfs volume inside an LXC container. I have an ubuntu LXC container, installed ceph-common, and tried a mount, but it failed as shown below: root@vis-lxc-02:~# mount.ceph vis-mgmt-1:6789:/ /ceph modprobe: ERROR: ../libkmod/libkmod.c:586...
