Comment 4 Vratislav Podzimek 2015-05-05 13:30:47 UTC
The problem is that the 'mdadm --examine --brief' doesn't provide the 'metadata=X' key-value in some cases and libblockdev expected that. The easy fix is to not require that key-value. I checked that blivet is ready to get the results with no metadata version set.

Comment 5 Fedora Blocker Bugs Application 2015-05-05 16:32:34 UTC
Proposed as a Freeze Exception for 22-final by Fedora user vpodzime using the blocker tracking app because:

 Could with high probability happen on some FW RAID installations.

Comment 6 David Lehman 2015-05-05 17:27:48 UTC
As I recall, the set of fields output by mdadm examine depends on the metadata version of the md superblock. It would certainly be nicer if it were consistent instead.

Comment 7 Doug Ledford 2015-05-05 17:36:04 UTC
This partially depends on whether you are talking about --examine or --examine --brief.  The latter is specifically intended to be a suitable ARRAY line in an mdadm.conf file, so the information displayed is only what's needed by mdadm to reliably, uniquely identify the array and preserve its current name.  I suspect it only outputs a metadata version for 0.90 arrays, and then only because that's a deprecated metadata version, but I could be wrong on the reason for it.  Neil might be amenable to making the metadata version output constant.

Comment 8 Dan Mossor [danofsatx] 2015-05-11 19:52:10 UTC
Discussed at the 2015-05-11 blocker review meeting[0]. Voted as AcceptedFreezeException.

AGREED: 1217900 - AcceptedFreezeException - any reasonable fix to a crasher in sensible anaconda usage is a good thing to get in (adamw, 18:09:12)

Comment 9 Adam Williamson 2015-05-12 22:12:26 UTC
We're now past the final freeze - it'd be good to get a build with this fix (and the other accepted FE in libblockdev, which is in POST state) ASAP, so we have longer to test. Thanks!
