Hello: On a vintage VAIO I have no problems with amd64 stretch. With a raid1-based on the X79 chip, upgrading from jessie to stretch (I need a higher CUDA version than available on jessie for latest experimental NAMD molecular dynamics) went on regularly. However, the command
# systemctl set-default multi-user.target (which worked fine on said VAIO to boot at the $ linux prompt) led to failure to connect to lvmetad, falling back to device scanning, whereby an endless disk scanning begun. I tried: 1) Super grub2 disk: OK it led to clean boot but I found no way to fix the problem. 2) Accessing the X79 computer from said VAIO (both are on a LAN) equally allowed to manage everything but I was unable to fix the problem. 3) From said VAIO: # systemctl enable lvm2-lvmetad.service OK, but it was lost on needed reboot. I never had to reinstall a debian amd64 but this time I am lost. Thanks for any kind suggestion francesco pietra
