Dear Community,
during an update of PVE from 8.4.1 to 8.4.5, I suspended all virtual machines and rebooted the server.
Once all came back online, I was shocked to see that all of my linux VMs were either
This was rather unexpected and I wonder what went wrong.
The steps I did to update the system were:
Now, I'm aware that the step of actually installing packages with running VMs might have been not so a good idea.
Nevertheless if this is known to be a problem, what can be done to avoid this from happening?
I think about a apt hook which reports "running VMs" when critical patches are applied.
This admin consent will act as a reminder to eventually avoid crashing the machines.
I'm happy to share my version information but since the previous versions before the reboot are not available, I wonder if this makes sense.
The server is a HPE DL380 Gen10 with Dual Xeon CPU (2nd Gen), 512GB RAM, several zpool with NVMe SSDs for the VMs.
Best regards,
Bernhard
during an update of PVE from 8.4.1 to 8.4.5, I suspended all virtual machines and rebooted the server.
Once all came back online, I was shocked to see that all of my linux VMs were either
- freezing
- showing systemd errors like "read only filesystem"
- were unable to boot (initramfs, unexpected inconsistency)
This was rather unexpected and I wonder what went wrong.
The steps I did to update the system were:
- apt update & apt-dist-upgrade
- Since many packages were upgraded, I decided that a reboot was necessary
- Suspend all running VMs
- Reboot system
Now, I'm aware that the step of actually installing packages with running VMs might have been not so a good idea.
