I think this is correct. If vda is pulled from the array you want it to boot from vdb without any manual intervention. Ok, agreed but if you boot from the second disc and the first is still present, is second disk referred as 0x80 or as 0x81 in bios. That may depend on the bios, but I'd expect 0x80. |
Description of problem: when installed on SW raid partition for stage 2 is always 0x80 which lead to first disk reported by bios Version-Release number of selected component (if applicable): RHEL 6.6 How reproducible: 100% /boot -> md0 / -> md1 Personalities : [raid1] md0 : active raid1 vdb1[1] vda1[0] 204736 blocks super 1.0 [2/2] [UU] md1 : active raid1 vdb2[1] vda2[0] 9412480 blocks super 1.1 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk [root@rhel6-test ~]# file -sL /dev/vda /dev/vda: x86 boot sector; GRand Unified Bootloader, stage1 version 0x3, boot drive 0x80, 1st sector stage2 0x8176, GRUB version 0.94; partition 1: ID=0xfd, active, starthead 32, startsector 2048, 409600 sectors; partition 2: ID=0xfd, starthead 159, startsector 411648, 18841600 sectors; partition 3: ID=0x82, starthead 254, startsector 19253248, 1718272 sectors, code offset 0x48 [root@rhel6-test ~]# file -sL /dev/vdb /dev/vdb: x86 boot sector; GRand Unified Bootloader, stage1 version 0x3, boot drive 0x80, 1st sector stage2 0x8176, GRUB version 0.94; partition 1: ID=0xfd, active, starthead 32, startsector 2048, 409600 sectors; partition 2: ID=0xfd, starthead 159, startsector 411648, 18841600 sectors; partition 3: ID=0x82, starthead 254, startsector 19253248, 1718272 sectors, code offset 0x48 Steps to Reproduce: 1. install RHEL on SW raid 2. check the boot device with fdisk -sL Actual results: vda: boot drive 0x80 vdb: boot drive 0x80 Expected results: I am not sure but each disk should lead to itself so it could be like vda: boot drive 0x80 vdb: boot drive 0x81 Additional info:
