Software RAID does not autorun on any platform that doesn't use MSDOS style partition tables because the only partition type in fs/partitions that calls md_autodetect_dev() is msdos.c. I'm attaching a patch that should make RAID autorun work on OSF partitions (although I cannot test it yet, since the installer crashes on me - bug #38790). Ideally, the add_gd_partition() function would be like the add_partition() function in 2.2, where the partition type was passed in (or just 0 if partitions didn't have types) and add_gd_partition would then have the logic to call md_autodetect_dev().
Created attachment 17068 [details] Patch to fs/partitions/osf.c to enable RAID autorun
Ingo: can you take a peek at this?
One other (possibly obvious) comment on this, especially since the release notes with RC1 suggest software RAID: compile the RAID modules in to the default kernel. The above patch is useless without that.
Ingo? Arjan? anybody? The above patch is not in the current cvs, is this a patch that we want? reject or apply?
