Hi All, Just wondering if anyone else has experienced a reboot problem. I have a intel motherboard based server of late 2004 vintage with 2 by 160GB SATA drives running linux software raid 1 with boot partition and /. The server was running 2.6.18-128.1.10 and had uptime of approx 40 days. I did a yum update and reboot yesterday and after the POST the screen showed GRUB
From memory this indicates that the mbr is corrupt and grub cannot find the required files on /boot/grub (the first partition). I did a linux rescue from DVD which sets the HW raid 5 as /dev/sda and the two OS drives as sdb and sdc then ran grub and did grub> root(hd1,1) # designates that the root is to be found on the second partition of the second drive grub> setup(hd1) #writes the mbr onto the second drive (/dev/sdb) grub> root(hd2,1) # designates that the root is to be found on the second partition of the third drive grub> setup(hd2) #writes the mbr onto the third drive (/dev/sdc) grub> quit reboot ALL was well. Question is, what has happened in the last 40 days to the mbr(s)?? Not sure where to start looking. Any thoughts Thanks Rob
