Hi,
I guess this is a bit outside proxmox, but I noticed yesterday my log was flooded with rejecting I/O. It started a few days ago with this in the dmesg:
Looking through the log files at that time I found:
It seems like the CD-ROM drive changed scsi id during operation? Has somebody experienced this before?
The error messages stopped when I shutdown two KVM machines which apparently was using the old CD-ROM device sr0. Could it be triggered by two KVM's having CD-ROM assigned although they did not use it?

pve-manager: 1.4-10 (pve-manager/1.4/4403)
