Hi there,
I have the problem that my zentyal machine, it doesn't start anymore after we had a power failure in our area. After a manual reboot the system stayed with the loading picture of zentyal for a while. Neither to switch to console 1 nor to anything else give a clue that the machine was doing. So I run the system from LiveUSB and could see that one of the raid disk had to resync (it took like 3 hours).
After another reboot of the system, now not even the grub2 loader appeared... So I started again with my LiveUSB-System, installed the mdadm library mounted the LVM partitions and run grub-install as well as update-grub. But still the same problem, after showing the BIOS logo the screen stays black... for me it looks like the system can't run the grub2 loader from the boot partition... Any ideas to solve or to narrow the problem down?
Hope you guy can help,
regards Valentin
