Hi, as many of you know, based runs inside vm(s) ontop of my server and shares its resources with other stuff I do and host. And yesterday when I finally decided that it was time for the maintenance, the upgrade from debian 8 to 9 horribly failed and resulted in a system that could not mount lvm partitions which contained the vms and basically all data. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774082 Tobi assisted me through the night while we tried to fix my vm host. In the end I had to go to bed while he continued working. At 4:30 in the morning he finally found the (trivial) fix to the problem. I might do some more fixes and restart during the next few days, but the main problem is solved.
