We installed a new Windows server 2022 on a cluster that uses an SSD-based ceph volume. All seems to be going well, when suddenly windows event log reports: "An error was detected on device \Device\Harddisk0\DR0 during a paging operation" It's Windows error # 51 There are other Windows...

I have setup a remote server in a different city to which I ship all backups using a sync job. The remote PBS datastore however doens't seem to be doing deduplication. The local PBS. Usage : 91.02% (3.97 TB of 4.37 TB) Backup Count CT : 32 Groups, 380 Snapshots Host : 0 Groups, 0...

I have seen a couple of blogs out there that claim one can simply use the pvesh command without any parameters and it will drop into an interactive mode where one can show the calls that can be done and a particular level. It doesn't work like that for me though and the documentation is really...

I need to extract which storage is assigned to each VM and LXC in our cluster. I can retrieve the total allocation for the boot disk, but can't see an obvious way to get the detail for each storage volume allocated. Some of our VM's have a boot disk on an ceph SSD pool and a logging disk on...

We're experiencing a problem with a FreeBSD KVM guest that works 100% on installation, but after a while starts complaining that it can't write to the disk anymore. What we have done so far: Moved the disk image off ceph to a lvm-thin volume Changed the disk from Virtio-SCSI to SATA and also...

Scenario: Centos Guest OS with 8GB/24GB RAM as min/max allocated. The machine typically uses between 10GB and 12GB of the allowed RAM due to ballooning, but here's a problem: Using free -h shows only 14GB in total available. Can't find anything else that shows the 24GB max allowed. There are...

I'm getting the error below after something happened (it was not happening before) and not sure that I changed anything deliberately. It prevent the status graphs (rrd, right?) to be displayed on the PBS administration section. Oct 11 22:07:17 pbs3 systemd[1]: Starting...

I have run into an issue a couple of times in that guest OS's slow down dramatically if the PBS server doesn't perform for whatever reason. Previously I had a network issue, which prevented backups from being written at a reasonable speed and it caused the guest machines being backed up to...

We ran into a very nasty issue a few days ago. Background: Systemd generates ridiculously long interface names (see https://manpages.debian.org/bookworm/udev/systemd.link.5.en.html and referenced here https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES) like...

When viewing a QEMU machine console with noVNC, the options are to either scale the screen locally, or not. When scaled locally, the text is so small that it's not practically usable. Disabling local scaling fixes that, but then the view screen cannot be shifted left / right or up / down, so...

I have a FreeBSD 12.3 guest running a poller node and when it gets installed everything runs just fine. We can stop and start the guest too, no problem. The guest uses VirtIO SCSI and uses an ceph RBD image of 120GB. The FreeBSD qemu-guest-agent is installed. If for some reason the VM is...

I need to do something about the horrible performance I get from the HDD pool on a production cluster. (I get around 500KB/s benchmark speeds!). As the disk usage has been increasing, so the performance has been dropping. I'm not sure why this is, since I have a test cluster, which higher...

I had a failed node, which I replaced, but the MDS (for cephfs) that was on that node is still reported in the GUI as slow. How can I remove that? It's not in ceph.conf or storage.conf MDS_SLOW_METADATA_IO 1 MDSs report slow metadata IOs mdssm1(mds.0): 6 slow metadata IOs are blocked > 30 secs...

I have a situation where a node failed (due to the boot drive failing) and then another node failed (due to RAM failure). There are 7 nodes in the cluster, so things kept running, but eventually there were many writes that could not be redundantly stored and the whole thing ground to a halt...

I have a failed boot drive in a 7 node proxmox cluster with ceph. If I replace the drive and do a fresh install, I would need to trash the OSD's attached to that node. If I could somehow recover the OSD's instead it would be great and probably save time too. Is that possible?

I have an LXC that is provisioned with a 100GB boot drive using ceph RBD storage. However, see the following: ~# df -h Filesystem Size Used Avail Use% Mounted on /dev/rbd10 98G 8.8G 85G 10% / This is in the running container. Checking the disk usage in ceph however, claims...

I the continuous process of learning about running an pmx environment with ceph, I came across a note regarding ceph performance: "... if running in shared environments, fence off monitor processes." Can someone explain what is meant by this and how does one achieve this? thanks!

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...

We had an interesting situation this morning. For some reason one node in our cluster was not showing as active (green "running" arrows on the guest icon on the tree) and all the LXC's were not responding. We managed to address the issue as quickly as possible by simply resetting the node and...
