Not sure what to say about that but going back to your problem...proxmox is debian linux underneath so if you have "no commands" as you say maybe you should try booting a System Rescue CD to see what is going on.

Assuming you have some type of home-made scale out load in mind... The only real way you can know if a VM is active is from within it, so make a script in your VMs to shut down when idle. Then in your proxmox nodes do something like: #!/bin/bash qm list | grep running if [ $? -eq 0 ] then...

I finally found that I had completely misunderstood the omping program. The command has to be run separately on all the nodes. I just ran it on one node with all the nodes listed in the command line and thought it would handle it all itself.

Hi, I've been thinking about auto-migration based on cpu usage: #!/bin/bash # script to auto migrate VMs to lower loaded node debug=1 baseload=4000 #get list of nodes, there is some other text to strip out nodes=$(pvecm nodes| grep -Ev "^$|Member|-------|Nodeid|(local)"|awk '{print $3}') if...

Not completely sure how I got here but it seems to me that you should create a big file in your VM (zeros or not) and then delete it. Writing zeros on its own would never issue a trim/discard but then deleting the file definitely would.

I read through that and established that multicast isn't working, but still everything seems fine without it. So that's why the question. I did find one thing wrong and that was that "ceph versions" is inconsistent and "ceph osd status" seems not work properly (hostname missing in some rows)...

Hi, I have installed a 16 node proxmox 5.1 cluster with a ceph hdd osd on each node, 5 monitor/mgrs, 2Gbit network. During installation I wasn't able to get multicast networking on the network switch. Everything seems to work so I am wondering what problems I should look out for. Is multicast...
