    Configure VLAN on VMs without using bridges

    Support of lazytime for mount points

    How could I enable lazytime mount option for lxc containers? Current mount options have only noatime nosuid when checking Mount point. P.S. Probably it may be done by direct editing of .conf file at /etc/pve/lxc?

    High latency on recently added SSD OSDs

    Hi, I added several dozens SSDs to Ceph cluster and found that Proxmox reports Apply latency for them from 200 to 500 ms. I checked with iostat program - zero activity. What could be wrong with them? P.S. No migration process happens - they are linked to separate 'root' container.

    Ceph pool may be deleted easily in UI

    Hi, I found simple way to get all CT/VMs unusable. Simply delete ceph pool in Ceph->Pools->Remove. No warnings or locks even it's used in any way. Running pve-manager/4.2-15/6669ad2c (running kernel: 4.4.10-1-pve) Regards, Alex

    [SOLVED] GUI displays 'grayed' nodes

    HI, Installed Proxmox 4.2 on 3 nodes and formed cluster. CLI tools like pvecm status/nodes show that cluster is OK. But GUI randomly 'grays out' nodes and randomly takes them back. No errors, quorum is established. I changed to udpu and back to multicast - no difference. What should I check...
