Hi all,
I used a kickstart script to setup a new machine of mine with RAID 1
(I couldn't get anaconda to create matching partition schemes). So I've
now got /dev/sdg1 and /dev/sdh1 as 'bios_grub' (/dev/sd{a-f} are a
separate array).
0 root@an-nas02:~# parted /dev/sdg print free
Model: ATA ST3000NC000 (scsi)
Disk /dev/sdg: 3001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags: pmbr_boot
Number Start End Size File system Name Flags
17.4kB 1049kB 1031kB Free Space
1 1049kB 3146kB 2097kB bios_grub
2 3146kB 3001GB 3001GB raid
3001GB 3001GB 466kB Free Space
0 root@an-nas02:~# parted /dev/sdh print free
Model: ATA ST3000NC000 (scsi)
Disk /dev/sdh: 3001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags: pmbr_boot
Number Start End Size File system Name Flags
17.4kB 1049kB 1031kB Free Space
1 1049kB 3146kB 2097kB bios_grub
2 3146kB 3001GB 3001GB raid
3001GB 3001GB 466kB Free Space
I can only boot off of /dev/sdh, so I tried to run 'grub2-install'
against /dev/sdg and it failed with this error:
*** Error in `grub2-install': double free or corruption (fasttop):
0x00000000010a83b0 ***
(full error: http://fpaste.org/139382/25324161/)
It seems like it's blowing up on grub2-probe, as I can generate the
same error. I tried specifying the device:
0 root@an-nas02:~# df -hP |grep boot
/dev/mapper/an--nas02_vg0-lv_boot 506M 133M 373M 27% /boot
0 root@an-nas02:~# lvdisplay /dev/an-nas02_vg0/lv_boot |grep VG

PV Name /dev/md0

So I am wondering how I can make /dev/sdg bootable? A RAID 1 array is
of limited use if I can only boot off of one of the disks. :)
Thanks!
