Here I am again. In the end, I did the upgrade from debian 7 wheezy to debian 8 jessie in order to update Slurm and solve some issues with it. It seemed it all went well. Even slurm problem seemed solved. Then I rebooted the machine and the problems began. I can't boot the master anymore returning an error:
*gave up waiting for root device. Common problems:- Boot args (cat /proc/cmdline)- check rootdelay= (did the sistem wait long enouth?)- check root= (did the sistem wait for the right device?)- missing modules (cat /proc/modules; ls /dev)ALERT! /dev/mapper/system-root does not exist. Dropping to a shell!"* *modprobe: module ehci-pci not found in modules.dep* *modprobe: module ehci-orion not found in modules.dep* *modprobe: module ehci-hcd not found in modules.dep* *modprobe: module ohci-hcd not found in modules.dep* *Busybox v1.22.1 (Debian 1:1.22.0-9+deb8u1) built-in shell (ash)* *Enter help for a list of built-in commands* * /bin/sh can't access tty job control turned off * *(initramfs)* Maybe did you ever had this type of problem?
