Posted: Thu Feb 22, 2007 12:35 am Post subject: RAID boot issue |
|
|
Hello,
Today I set up a RAID 1 configuration on an existing system (migrated data). Everything was going great, I was booted to the RAID, and it was in the middle of rebuilding the contents of the mirror on one of the disks when the power went out, worst case scenario
Now my machine won't boot because it isn't finding a bootloader, and when I try to install a boot record by booting a livecd, configuring the RAID again with mdadm (with just one of the disks), chroot, and then run silo, I am told that the RAID is not fully active and therefore it cannot install the bootloader.
Any help?
Thanks!

Moved from Other Things Gentoo to Gentoo on Sparc.
You mentioned silo, so it sounds like a Gentoo on Sparc issue
you may get a better response here. _________________ Regards,

It sounds like you need to have the raid1 fully online before writing the bootblock again with silo.
One thing though - did you start any raid partitions at cylinder 0 on any disk? I've been bitten by that before, on sparc you definitely need to start from cylinder 1 otherwise the bootblock and the raid partition will occupy the same space and Bad Things(tm) will happen - like an overwritten bootblock. |
