    qm command to remove devices such as a disk from the vm config?

    Hi. I know i could do this in the UI, but i'd like to know how to do it on the command line. To add a disk i can do qm set vmid --scsi0 /dev/disk/by-id/diskid What would the qm command be to remove the disk above? Thanks.

    error when running pct commands.

    Thanks for the nudge, updates applied successfully and all works now. I must still have been sleeping as i ran apt upgrade instead of apt dist-upgrade

    error when running pct commands.

    Hi. When running a pct command, for example pct start 100 I get the following error. Undefined subroutine &PVE::Tools::upid_status_is_error called at /usr/share/perl5/PVE/CLI/pct.pm line 33. This started after upgrading from pve 6 to 7. The command does complete successfully and things still...

    Suggestion - Possibility to provide SMTP credentials during installation or in the WebUI

    Hi. Let me add a +1 to the Possibility of configuring mail settings in the UI. I came to google looking for a way to do it for my systems. I'll most likely push out the settings for the company setup via ansible, but for personal use where i just have one system it would be much faster to...

    unique vm ids across clusters?

    Actually, there is one scenario where they do interfere with each other, unless i'm reading things wrong. Consider the following setup. 2 proxmox clusters, in separate physical locations with a site to site vpn joining the 2 locations. A proxmox backup server with one storage array at site1. If...

    unique vm ids across clusters?

    Hello. For those of you running multiple proxmox clusters, is there a reason to enforce unique vm ids across the entire infrastructure? or would this be an unnecessary complication? If you do enforce unique vm ids, how do you do it? We're working on an ansible project to automate vm/container...

    Unable to ping or ssh from secondary pve host to primary pve host

    Hi. Question, from the main host can you ping any of the vmbr interface addresses? 10.1.3.30, 10.1.3.31? Also, why is the bond config different between the hosts? From what you posted this should work. Using something like tcpdump to see the packets might be needed. Thanks.

    Unable to ping or ssh from secondary pve host to primary pve host

    Hi. Could you post the contents of /etc/network/interfaces from both hosts? Also, log into both hosts and varify firewall is disabled, it is by default so unless you ever enabled it it should still be disabled. Thanks.

    High disk IO overhead for clients on ZFS

    Hi. I think i've come across the issue and it's rather obvious once you get all the various differences ironed out. I would like some comments from others to tell me if i'm on the right track. The issue isn't actually overhead but differences in volume vs dataset configuration. basically a...

    Hosts and containers are pretty well the same, it's vms that we're having trouble with. Thanks.

    Hi. Another update. I'm now testing with /dev/urandom and a 128 block size. following are 2 results, one from the vm and one from the host. There is still a difference. root@chestnut:~# dd if=/dev/urandom of=/dpool/test bs=128K count=100 oflag=dsync 100+0 records in 100+0 records out 13107200...

    High disk IO overhead for clients on ZFS

    Hi. I'm a co-worker of the origional poster and we have a few more questions. Using lxc with a bind mount does indeed get us bare metal performance using the priorly mentioned dd command. However, i'm wondering. Is there a definitive guide on what the performance overhead is for proxmox vms? I'm...

    Beginner needs advice for host SSD / HDD configuration

    Hi. Sharing the drives for the proxmox instal and the vms is simple and works well. I'd ditch hardware raid and set up proxmox using zfs raid1. Once installed you will have a local-zfs datastore that has the remaining space not used by the proxmox install that you can set up your vms on. If zfs...
