    Proxmox hang when stop/shutdown lxc-container after update host

    I thought that this was related to privileged containers, but later I caught similar freezes on unprivileged containers too. What was common in all cases was a preliminary host update: Start-Date: 2024-03-02 14:47:02 Commandline: apt dist-upgrade Install: pve-kernel-5.15.143-1-pve:amd64...

    I have repeatedly come across a situation in which updating the host (kernel and some other components) leads to the fact that when the container is stopped, the host freezes. Is it possible to solve this problem in some way, in addition to the method of first stopping all containers before...

    DiskIO in CT missing

    [SOLVED] CEPH IOPS dropped by more than 50% after upgrade from Nautilus 14.2.22 to Octopus 15.2.15

    I don't know what the norm should be, I can only suggest. But performance has doubled and allows the use of CEPH in prod.

    [SOLVED] CEPH IOPS dropped by more than 50% after upgrade from Nautilus 14.2.22 to Octopus 15.2.15

    Thanks, I know about this document and I don't find NUMA architecture in EPYC (Zen 2) unpleasant, on the contrary - a lot of customization options make it flexible. About Ceph, current bench show next (also not any tunings, just waited few days): # rados bench -p bench 30 -t 256 -b 1024 write...
