I have been using a guest hookscript for a few years that runs fsck on disks on the pre-start hook. It does this because the VM I am running uses a kernel boot file and so there is no opportunity to check the disk from within it. Anyway, the script ran but didn't find the disks. Long story...

I have a 5 node system where only 1 - 3 have any workload, a mixture of imported KVM VM's and new containers. This morning something wasn't right with one of the containers which was responsible for a couple of intranet websites. As we couldn't ssh to the container we went to look to see if it...

All, have a cluster of 3 dell servers running about a dozen VM's and containers rebooted itself and I cannot find a reason why. At the moment it looks like all 3 rebooted at precisely the same time. Previously, I have had this happen (as expected) due to watchdog timeout should networking be...

I am not quite sure what's happening here. I am migrating a VM that has a disk that is 48G vm-101-disk-2 But when migrating it finds a whole lot more to migrate that I expected. Migration In the pool for 101 I find: What are these sub-vols and where did they come from? Are they...

A question I have had for a while and never got around to asking: I have many Proxmox clusters which usually contain 3 nodes, Xeon 128Gb SSD. What I don't really have a feel for is what capacity those nodes have for the number of concurrent VM/containers. As an example I migrated 6 VM's which...

I created a simple hookscript based on the example and attached to my VM. $ qm start 109 hookscript error for 109 on pre-start: command '/mnt/pve/replica/snippets/wms-precheck.pl 109 pre-start' failed: open3: exec of /mnt/pve/replica/snippets/wms-precheck.pl 109 pre-start failed: Text...

Early days, can't make heads or tails of it but we have a cluster of 3 nodes with HA, replication happily chugging along. When we came to add a 3rd node basically looks like all hell broke loose, all 3 nodes restarted red x's on the nodes, couldn't get in on the web interface. All VM's were...

I have a replication job that has been running for 20 hours and is blocking all the other replication jobs. Due to a change I need to abandon the running job. It should be using the migration network but wasn't configured correctly when started. Which is the best way to do this?

Still having the same issue as I've always had, and its really a showstopper for the use of proxmox for anything important. Have a VM imported from legacy KVM previous version of qemu. Everything runs perfectly fine except when you perform a backup to snapshot about 1/10 times this breaks the...

I recently migrated / imported a bunch of machines from KVM. Today one of them is throwing an IO error which doesn't appear to have caused an issue -but maybe just not discovered what that issue is yet, Mar 27 11:20:56 gesyar3 kernel: [948952.805107] EXT3-fs (vdb): error in ext3_new_inode: IO...

Hi, I have a 3 node network and each node has two networks the primary 1Gbit and a secondary 10Gbit. We are using the secondary for replication. A backup server also has both these networks. Can the backups be made to go via the backup network? At the moment I think they are going via the...

I have multiple legacy VM's that do not boot on the latest version, but ran fine on a recent but previous version. V7.3-6 Previous Version: V7.2-3, same machine, booted and at login prompt. They are identical machines, the newer server is restored from a backup. To check the backup I...

I have 3 nodes joined together and I have imported some legacy KVM virtual machines. These require kernel boot images which I have configured in the conf file as an argument. At the moment I have put those files on an NFS share that all nodes can see so they have the same path on all nodes...

Sometime last year I found that when snapshotting a running container with mariadb would cause the database to be unable to complete any queries - the process was running but queries just stacked up. It was as if the fs was missing briefly but could not recover. It was assumed it was a mariadb...

One of our datacentres had a power outage but the proxmox mode was not shutdown before the power was lost. There has been some updates applies a few weeks ago to take it to 7.2.3. After the restart the IO delay has reduced - which sounds like a good thing. Is this expected and is there...

I recently set up three nodes running a fairly small VM which consists of 3 disks 25/4/25 Gb so 54Gb in total. Migration of that VM from one node to another tops out at 120 Megabit/s. You can quite clearly see the limitation on the IO graphs. I can quite happily get 950 Megabits between...

For some historical reason some of our VM's have kernel and init ram files. We specify these using the args shown at the bottom. I had putthe files into a network share that has been added to the proxmox host via cifs. Initially I put these files [vmlinuz-2.4.21-144-smp4G] into...

I've asked a similar question but didn't get any response. I have a container with a large 250Gb busy database. Its Ubuntu 22.04 fully up to date and running latest MariaDB 10.6. Every 20 mins there are many commits to that database totalling a few GB per day. If I create a snapshot of that...

I created a small container running 22.04 and MariaDB and run a small database of about 250G in size. The database is busy and every 20 mins a couple of million rows gets fired into it from 8 threads. I created a snapshot of the container earlier and then proceeded to create a clone of the...

I have 3 nodes in a cluster all running on a 192.168.6 subnet with a gateway of 6.4 and that all works fine, my containers can get a real IP via DHCP. I wanted to have a second subnet. 192.168.80. I tried this on my nested proxmox cluster and that all worked fine. When I add 80 subnet to my...
