    Some client(s) are unable to authenticate to Ceph but which ones?

    This past weekend I completed migrating my config management to Ansible and updated all PVE packages, rebooting each node as I did so. Afterwards, 4 of my 5 nodes started throwing errors that some Ceph client(s) using the client.admin client are unable to authenticate...

    Installing "ceph-exporter" Daemon

    According to the ceph documentation, at least as of Reef, the mgrs no longer export perf counters by default (https://docs.ceph.com/en/reef/mgr/prometheus/#id1) which I thought wouldn't be a big deal for me. However, some of these counters include OSD storage information, in particular...

    ceph-mgr crash when enabling perf stats

    I'm having some performance issues on CephFS I'm trying to track down. I tried enabling stats following the information on https://docs.ceph.com/en/quincy/cephfs/cephfs-top/. The second I do ceph mgr module enable stats, all of my MDSes start to puke the following: 2023-02-19T21:19:31.164-0500...

    Corosync KNET Flapping

    Every so often (like right now), I'll start seeing a lot of KNET logs about a link going down and coming back up. Sometimes rebooting one node will fix it, sometimes it won't. It seems to happen randomly after node reboots or some other event. How can I determine which node is causing this or...

    [SOLVED] No perf counter for schema for mon.#

    In preparation for upgrading to Ceph Quincy (from Pacific), I had to remove and re-add three of my monitors as they were still using leveldb. Doing this through the GUI didn't work as it was somehow unable to find monitors with that ID. These are fairly old monitors so I ended up having to do...

    Windows 10 VM with GPU Passthrough Chugging after Upgrade to Proxmox 7.0

    For the past few years I've been gaming on a Windows 10 VM with a GTX 1070 Ti. This has been working surprisingly well. After upgrading to Proxmox 7.0, the VM is now chugging seemingly randomly. I can play for an hour or two fine but then suddenly, I'll start getting "skips" for about half...

    Confusing Ceph GUI Info when using multiple CephFS volumes

    I recently upgraded to Proxmox 7 and Ceph Pacific which brought multiple CephFS support. My goal was to create one FS on my HDD OSDs and one FS on my SSD OSDs so I can balance workloads across the two sets of hardware. I have a "performance" and "capacity" crush rule. Previously, I had 2 RBD...

    [SOLVED] Can't migrate VM on Ceph when source node _also_ has local-zfs but VM isn't using it

    I have four nodes setup with Ceph, one of which _also_ has ZFS setup. All of my ISOs, etc. are on ZFS. This particular VM was running on a node _without_ ZFS, just Ceph. I had to take that node offline today so I migrated it to the one _with_ ZFS. After bringing the node back up, I cannot...

    Permission denied when trying to create ceph-osd on zvol

    I just upgraded my cluster to Proxmox 5.1 and am trying to upgrade one of the Ceph OSDs to Bluestore. I've shut down and removed the old OSD completely. From the crush map, auth, and the cluster: cluster: id: 2b70b442-d912-4d6b-b9ad-b359b9339e4f health: HEALTH_WARN...

    pve-qemu-kvm has been kept back

    Hi, I just did a test upgrade from 4.4 to 5.1 on a freshly installed test VM after it has been configured to match my production hosts. The upgrade had a few minor issues that needed to be solved but I'm hitting one that I'm not sure how to deal with. It seems that apt wants to keep the...
