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

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:

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!
