Bug#504397: ext2_or_ext3_boot check fails when /boot is RAID
I suggested putting the following patch into d-i just before the release of lenny but never got an ack/nack. Since this issue is still there, I'm thinking of putting the patch in now. Can some partman experts comment on it? * Martin Michlmayr t...@cyrius.com [2009-01-06 16:56]: We have a partman check that ensures on some devices that the /boot partition is the 1st primary partition. Unfortunately this check fails when /boot is a RAID device, but it's actually valid for /boot to be a RAID1 device (as long as its physical partition is the 1st primary partition). There's currently no good way to map the RAID device to its physical partition to performs these checks, so I was thinking of applying a patch for lenny to skip the check if the /boot device is RAID1.

Bug#504397: ext2_or_ext3_boot check fails when /boot is RAID
Package: partman-ext3 Version: 54 The ext2_or_ext3_boot check I added has a problem: when you put sda1 in a RAID for /boot, the check will complain that /boot is not on the first primary partition. However, a RAID /boot partition is okay as long as it's on sda1/sdb1. The ext2_or_ext3_boot check should find which partition the /boot RAID belongs to. Frans, any idea what the best way is to do this? -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
