Hi, I did an upgrade from debian 7 wheezy to debian 8 jessie on the master of a cluster (1 master + 8 nodes). It seemed all went well. Then I rebooted the machine and the problems began. I can't boot the master anymore returning an error:
*Running scripts/local-block* *Unable to find LVM volume* *Running scripts/local-block* *Unable to find LVM volume* *... (lot of times)* *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)* Anyway, in grub there are two available kernel to boot *kernel 3.2.0-4-amd64* *kernel 3.16.0-4-amd64 (that is **3.16.43-2 kernel**)* Truly, it boots correctly with the old kernel 3.2, but not with 3.16. In the kernel 3.16 case, moreover, when the initramfs prompt is shown, it seems not to load the usb keyboard so i'm truly able to do anything. I tried to boot in 3.16 recovery mode and I get the same error. lvm2 module is installed and up to date. The system has 6 hard disk in raid as far as i know. What is happening? Thank you very much Elisabetta
