    qm set --sshkey

    So can I provide additional keys as new lines in GUI here? And if --sshkey accepts a file, does it also accepts several lines with several keys here?

    3 node Ceph-cluster upgrade from 7.0-13 to current - Ceph?

    Hi am running a 3-node proxmox/ceph cluster which is sheduled for an upgrade to the current PVE version, which as of today, is 7.3. The plan was to perform a "rolling" upgrade, starting with upgrading one node at first, and then after a week, also upgrade the remaining two nodes. When...

    [SOLVED] (safe/best) way to temporarily operate a cluster with only one node?

    Hi @Dunuin , thanks for your help! Sounds very interesting… So, like putting two low power intel NUC or any other (more) energy efficient devices running PVE in the rack and add them to the cluster, for quorum only? Cool! :) Having five nodes again would allow me to temporarily shut down the...

    PBS datastore 100% full - manual GC/prune does not work

    Hi Matthias and thanks for your quick help! As the first PBS still looks fine - I would delete the .chunks folders content, then set the vanish option on the sync job (that I totally missed) and finally do a resync or wait for the next sheduled run. So if the the vanish option is set I would...

    PBS datastore 100% full - manual GC/prune does not work

    Hi, I have two PBS servers in my setup. The primary one is ok and working as expected. The second PBS has a sync job to basically clone the content from the first PBS. Thats all it does.

    Slow VM on external CEPH Cluster

    Hi and sorry for adding in here with a question and no answer. Did you finally found a solution to this issue? Or did you stay on iSCSI? I am currently experiencing the exact same behavior on a somewhat similar setup. Windows disk usage nearly always at around 100% on an all Flash cluster...
