I added the comment about not powering off until the rebuild is complete. I found out the hard way and lost my root volume, which contained everything but home directories (so no data lost, just the whole system and all programs have to be rebuilt from scratch). 70.66.33.125 11:22, 24 August 2006 (UTC)

I added the note about the journalling filesystem crashes, after my ext3 partition got severious problems from one start to another. Another question: I don't find CONFIG_BLK_DEV in kernel-config (2.6.17-gentoo-r8), but CONFIG_BLK_DEV_MD - is this the same? There is also CONFIG_BLK_DEV_DM ...? --84.148.168.221 10:15, 23 September 2006 (UTC)


I have used this method several times successfully. Though recently I did run into an oddity. rsync in single user mode (init 1) is *slow*. Really slow. I had an rsync going for 24 hours and it was still building the index. Rebooted to normal multi user mode and within 30 minutes the rsync is well into actually syncing files. I cant figure out why rsync on this one machines is so slow in single user mode. Ideas are welcome.

You could check if DMA is on for the drive: hdparm -d /dev/hdX --Ahbritto 03:45, 12 March 2007 (UTC)

I re-worked this since it seems that dmraid is no longer the way to do this. --151.204.163.218 18:07, 25 February 2008 (UTC)

Could someone please add examples of grub.conf? And perhaps also about adding grub to both discs?
