Hello all,

After changing a failed disk, i am trying to verify is all ok, and i have noticed a strange thing:

cat /proc/mdstat Personalities : [raid1] [raid0] [raid10] [raid6] [raid5] [raid4] md1 : active raid1 sdb2[2] sda2[0] 31455160 blocks super 1.0 [2/2] [UU] bitmap: 0/1 pages [0KB], 65536KB chunk

md3 : active raid1 sdb4[2] sda4[0] 200164280 blocks super 1.0 [2/2] [UU] bitmap: 2/2 pages [8KB], 65536KB chunk

md2 : active raid1 sdb3[2] sda3[0] 2096116 blocks super 1.0 [2/2] [UU] bitmap: 0/1 pages [0KB], 65536KB chunk

md0 : active raid1 sda1[0] sdb1[2] 10481592 blocks super 1.0 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk

unused devices: <none>

grub> find /boot/grub/stage1 (hd0,0)

Are you calling it during boot in grub legacy command line or on booted system in grub legacy shell? I am calling it on the booted system in a grub legacy shell. Ok, and what is in /boot/grub/device.map? cat /boot/grub/device.map (hd0) /dev/disk/by-id/ata-GB0250EAFYK_WCAT1J075574 (hd1) /dev/disk/by-id/ata-GB0250EAFYK_WCAT1H882820 I have noticed now that device.map is wrong, and report the old (hd1), not the new.... In my system now i have:

/dev/disk/by-id/ata-GB0250EAFYK_WCAT1J075574 /dev/disk/by-id/ata-ST3360320AS_6QF1N350 I have to change manually the wrong entry on device.map, or there is a method more "SuSE like" to do that?

...

Notice the grub find only seen a drive?

Grub legacy does not normally search anything - it takes whatever is in device.map.

My question is...why? Ever seen all the two drives with Raid 1 systems... Now i have a paranoia...if the first drive fails, the second can boot? I cant test this, because that system is in production.... The system is an OpenSuSE 12.2 (x86_64). I am doing something wrong?

Thanks,

Claudio.
