Hello list.
Since morning I have an emergency. After last kernel update one of my servers didn't start. On display I see only "GRUB" :( I have 2 more servers based on CentOS too, but after the same update this servers works.
All servers have 2 HDs and works as software mirror.
I have started damaged machine using Knoppix and I can see partitions and data on both disks. Of course I have made a backup.
Anybody has the same problem? It can be hardware problem - HD diode light all the time. Or maybe something went wrong during update?
Regards
