@Richard thanks for following up. Unfortunately this issue not easy to reproduce as it happens inconsistently. Further, our proxmox nodes are in the DMZ so we can't really turn off the firewalls. So far, what I've done is moved that last VM (150) onto it's own proxmox node (they aren't...

@Richard just checking in on this, any ideas? we've been looking to see if it's network related, but haven't found anything conclusive yet.

Hi Richard - Thanks for responding! I've attached the results below. I stripped out all the unique identifiers like MAC and IP addresses. These nodes sit in a datacenter on a public subnet, but there are hardware firewalls and ACLs in addition to Proxmox. However, not sure how those would...

Hi all - I have a production proxmox node setup and it's been working fine for the most part now for a couple months. One thing I've noticed is that intermittently it stops responding. The GUI stop loading and I get a "Unable to Connect" error. When that happens, SSH fails to work too. Ping...

so just wanted to close the loop on this thread.. it turned out it was that the servers I was working on did not have the VM HW enabled in the BIOS. I had checked for it previously and didn't find it, but on a second pass it was discovered. The strange part is that the proxmox OS was reporting...

sorry, i didn't post that info as I know my raid is sync'd. it was made weeks ago. i have multiple nodes and have deleted the raid on a few of them to test, as I said above, different storage variations, so this speed issue I am seeing may not be linked to the software raid specifically...

hi lnxbil.. when you say software raid isn't supported, does that mean for storage as well or just the OS? To clarify, I have my OS installed on it's own physical drive using the proxmox defaults. In the server I have 5 other physical drives that I want to join together to use for local...

cool thanks appreciated.

thanks, will go with raid10 and test that out. right now we are doing 4 1TBs plus 1TB hot swap. if there's a recommendation for the filesystem to put on the RAID for best use in Proxmox as a "Directory" storage volume that'd be good to hear too! I was going to use ext3

thanks for the response. but yea, this is a dell C6220, it's a really powerful server. the proxmox UI loads fine, it's the VMs that are super slow. additionally a clean install of Ubuntu can't seem to use virtio for networking. this is all a bit off it seems to me.

Hi - I am in the process of setting up a PVE 4 environment. I have multiple nodes that will be clustered, but for now I am testing it on one node that has 6 physical discs. /sda is the PVE OS and then I have combined the other disks into a software RAID6 drive using mdadm. I then ran the...
