On my upgraded and still stable test system (intel i3) my VM's use write back but on my upgraded main system (intel i7) the VM's mainly use no cache and will crash on the latest kernel. I was able to choose 5.4 and get back up and running without crashes (so far).
As for what the actual fix is...
After running stable for about a day on the older kernel (Linux 5.4.124-1-pve) I did a bios update to the latest because I read that may help. I also tried to setup dumps on a remote machine (but that failed). I started the latest 5.11 kernel and was up for about 4 or so hours before it crashed...
Quick update: I rebooted a while ago and selected an older kernel (Linux 5.4.124-1-pve) and it seems to be more stable. I shutdown my LXC and my VM running with hard drives passed through to it. Not sure what (if anything) has helped but I'm semi running for now.
If there are any suggestions...
Hello,
I've been having multiple crashes a day after upgrading from pve 6 to 7. I first tried on my test system (a small i3 with 12GB of RAM) and it worked OK. This machine runs TrueNAS Scale for testing and supplies ISCSI storage to a VM on my main PVE system. I have passed through 2x 3TB...
