Description David Lehman 2011-08-23 14:07:57 UTC
Description of problem:
Anaconda does not support use or creation of linear md arrays. It probably should.

Version-Release number of selected component (if applicable):

I'm about to push a patch that will cause us to silently ignore linear arrays instead of the current behavior of crashing, but it would be better in the long term to add real support for linear arrays. There is an overarching assumption throughout anaconda that raid level is a numeric value, which is what makes this non-trivial.

This would be a good candidate for something to fix with or after the UI rewrite.

I'd be interested in working on this. If Dave doesn't find the time to do it feel free to assign it to me.

Comment 2 David Lehman 2015-01-20 17:40:14 UTC
We don't need to support creating these in anaconda, but it would be worth verifying that we can install to preexisting linear md arrays. Not a high priority.

These days RAID level is abstracted and no longer expects that every RAID level will be a number. Linear RAID is one of the defined RAID levels. So original description has become partially obsolete. Reassigning...
