From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040616 Description of problem: Grub doesn't install MBR on to both software RAID1 disks during install. Version-Release number of selected component (if applicable): grub-0.95-3 How reproducible: Always Steps to Reproduce: I did a custom install with software RAID with 2 SCSI disks. /dev/sda1 <-> /dev/sdb1 RAID1 (4G) /dev/sda2 swap /dev/sdb2 swap /dev/sda3 <-> /dev/sdb3 RAID1 (4G+) Installs as normal. After installation completes, I rebooted the server and hangs after BIOS scans. Summary ------- 1. Custom install with Software RAID1 running on SCSI "/". 2. Reboot after install completes 3. Server hangs immediately after BIOS scans. Actual Results: I rebooted the servers after fresh install and hangs after BIOS scan. Sometimes it displays a blank screen, sometime a flashings cursor at top left and once it displayed "GRUB" and hangs. Expected Results: I should see a nice grub GUI boot menu and boot up the machine. Additional info: I tried on 2 different machine setups. config 1) DUAL P3-500Mhz Intel L440GX+ Serverboard onboard Adaptec aic7896 controller 2 * 9G SEAGATE ST39204LC 512Mb RAM. config 2) P3-500 Intel SE440BX2 desktop board Adaptec 2940 SCSI controller 2 * 9G SEAGATE ST39204LC 256MB RAM Both have the same problem. I got round the problem by updating the MBR in rescue mode. http://www.fedoraforum.org/forum/showthread.php?t=26912
I am seeing the same behaviour installing on 2 120GB maxtor IDE ATA-133 disks. I can't seem to get the boot screen with the workaround suggested with the fedoraforum.org pages Kent, Can you pls change the summary to remove SCSI
Just as a side note, similar happend to my when installing FC4 (booted from rescue CD and did install from DVD image on spare partition, due to lack of DVD drive in the system) onto sda and sdb in SW-RAID1 mode attached to the Symbios HBA on an HP'ed ASUS CUR-DLS. I had to do a rescue boot and install grub onto the MBR of sda manually. # more /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb1[1] sda1[0] 264960 blocks [2/2] [UU] md0 : active raid1 sdb2[1] sda2[0] 3148672 blocks [2/2] [UU] # df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 3.0G 1.7G 1.2G 59% / /dev/md1 251M 33M 206M 14% /boot /dev/shm 442M 0 442M 0% /dev/shm # fdisk -l [...] Disk /dev/sda: 36.9 GB, 36951490560 bytes 255 heads, 63 sectors/track, 4492 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 33 265041 fd Linux raid autodetect /dev/sda2 34 425 3148740 fd Linux raid autodetect /dev/sda3 426 556 1052257+ 82 Linux swap / Solaris Disk /dev/sdb: 36.9 GB, 36951490560 bytes 255 heads, 63 sectors/track, 4492 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 33 265041 fd Linux raid autodetect /dev/sdb2 34 425 3148740 fd Linux raid autodetect /dev/sdb3 426 556 1052257+ 82 Linux swap / Solaris [...]
