  1. Disk errors on FreeBSD 12.2 guest

    We have recently upgraded to kernel 5.15 and now were having disk errors on one guest running FreeBSD 12.2. The config is: undefinedagent: 1 balloon: 8192 boot: cd bootdisk: virtio0 cores: 8 ide2: cephfs:iso/FreeBSD-11.4-RELEASE-amd64-disc1.iso,media=cdrom memory: 32768 name: VO-IRIS-Poller...
  2. All LXCs and VMs lost networking!

    I had a really perplexing situation last night. I had previously upgraded one or four nodes running the latest pve to pve-kernel -15.5. Because the naming of the network interfaces was changed at some stage, I had to recreate the /etc/network/interfaces file with the new nic names on all the...
  3. Memory management: ceph

    I see that ceph manages memory automatically according to https://docs.ceph.com/en/latest/rados/configuration/bluestore-config-ref/#automatic-cache-sizing Is the following normal for automatic cache sizing then? Granted, some of the machines have only 8GB of RAM and are used a storage nodes...

  5. lxc doesn't start properly after upgrade to pve7

    I upgraded my nodes from PVE 6.4 to 7, checked in advance with pve6to7 for any issues and all seemed to have gone well, except I have one container that starts, but not properly. If I do pct start 138, no error is returned, but the container doesn't run, although it's reported as running. ~#...
  6. OVH and Proxmox

    We are looking to add some services in Europe for clients and have been scouting for suitable hosting space. OVH seems to be one of the only options that offer Proxmox hosting. However, from their many options to select from, we can't quite figure out which is the most suitable one. We would...
  7. [SOLVED] PVE 4.4 sources problem

    I have to reinstall a couple of nodes on a cluster that I cannot upgrade to a newer version because some of the nodes only have 8 GB of RAM, so I need to get the 4.4 sources. However, something is wrong: ~# cat /etc/apt/sources.list deb http://ftp.debian.org/debian jessie main contrib #...
  8. [SOLVED] VLAN bridge problem with gateways

    I have a situation where I need different networks for different application groups on a single pmx cluster. To achieve that I have added VLAN's to the config as below. I have repeated the config on each node of the cluster. I have various virtual machines that are configured on the various...
  9. [SOLVED] lxc uid mapping woes

    I'm struggling to understand from the example here what the complete logic is behind the uid/gid mapping. I have a container (100). I want to map uid 1034 (which I created for this purpose) to uid 1034 inside the lxc. So, following the example in the above documentation, I added to...
  10. [SOLVED] Cannot read remotely mounted backup datastore

    I have installed PVS 2.0 on a LXC to test an play around with. All is good, except the following: To have some decent storage to write backup to I have mounted a location with sftp as follows: sshfs backup@192.168.121.34:/mnt/pve/cephfs /mnt/cephfs (I have 'hijacked' the backup account...
  11. Error getting osd journal information

    Proxmox 6.4 When I issue this command I get an error and no result: # ceph-osd --get-journal-fsid --osd-journal=/dev/sde -i 23 2021-09-29 22:14:58.319 7f59ee497c80 -1 asok(0x55eb542d8000) AdminSocketConfigObs::init: failed: AdminSocket::bind_and_listen: failed to bind the UNIX domain socket to...
  12. SATA vs SAS for ceph

    Hi all, In your practical experience, when I choose new hardware for a cluster, is there any noticable difference between using SATA or SAS drives. I know SAS drives can have a 12Gb/s interface and I think SATA can only do 6Gb/s, but in my experience the drives themselves can't write at 12Gb/s...
  13. vzdump trouble again

    I have one lxc that I cannot back up. Here's the log: # cat /mnt/pve/cephfs/dump/vzdump-lxc-148-2021_07_25-12_32_35.log 2021-07-25 12:32:35 INFO: Starting Backup of VM 148 (lxc) 2021-07-25 12:32:35 INFO: status = stopped 2021-07-25 12:32:35 INFO: backup mode: stop 2021-07-25 12:32:35 INFO...
  14. [SOLVED] LXC backup has started failing, was working before

    I have to lxc's that I cannot backup any more. It may have started happening after a recent minor upgrade to proxmox, but I'm not sure. If I start a backup, I see: INFO: starting new backup job: vzdump 106 --storage cephfs --remove 0 --mode snapshot --node FT1-NodeA --compress zstd INFO...
  15. New Windows 10 devices after node update?

    I updated Proxmox on a node last night and since a new kernel installed, I restarted the node. The VM and LXC's came up seemingly properly, but this morning users were complianing that the machines aren't reachable over a network. (2 Windows 10 machines, KVM guest). On further investigation...
  16. [SOLVED] Rules don't have the desired effect

    I want to isolate some machines from all the others in the cluster, having them only accessible from the internet. So I have set up some rules to attempt to achieve this, but they either appear to be ignored or I'm doing something wrong. +internet_access is defined is follows...
  17. [SOLVED] Firewall GUI rule activation

    When adding firewall rules via die GUI, does one have to activate the rules from the command line? How are the rules loaded/activated otherwise?
  18. Firewall rules number column not wide enough and cannot be resized

    When 10 or more rules are created, the column width for the rule number is not wide enough to display the full number and it cannot be resized the way other columns can. Can this be remedied please?
  19. [SOLVED] Correct way to restart a node without stopping containers or vm's

    Is there a correct way to restart a node (mostly for applying kernel updates)? I have about 20 virtual machines and containers that should not go down ever unless planned. So I have set the all as HA. When I shutdown a node, the VM's / LXC's shut down instead of migrating to the node next in...
  20. [SOLVED] pfSense in a VM with HA

    I'm trying to figure out how I could install a pfSense VM and make it HA. I have a ceph cluster of 4 nodes (but there will be nodes added regularly), so I can give each node a public IP address on one of it's ethernet ports. Creating a bridge and adding that to the pfSense VM will give me a...
