Nominating as a Beta blocker: https://fedoraproject.org/wiki/Fedora_22_Beta_Release_Criteria#Hardware_and_firmware_RAID , "The installer must be able to detect and install to hardware or firmware RAID storage devices."

scratch build with a potential fix:

logs from install attempt with the scratch build

With the scratch build it no longer crashes, but the set does not appear as an available installation target (so if your only target is a RAID set, you can't install).

Attaching the logs (all smooshed into one file by fpaste).
Comment 16 Adam Williamson 2015-03-30 18:21:49 UTC 
Discussed at 2015-03-30 blocker review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2015-03-30/f22-blocker-review.2015-03-30-16.04.log.txt . Accepted as a blocker per criterion cited in #c13.
Comment 17 Vratislav Podzimek 2015-03-31 14:41:20 UTC 
So the key is this (from storage.log):
17:34:05,125 DEBUG blivet:           DeviceTree.handleUdevDeviceFormat: name: sda ;
17:34:05,136 INFO blivet: type detected on 'sda' is 'isw_raid_member'

17:34:05,140 DEBUG blivet:             DiskDevice._setFormat: sda ; current: None ; type: mdmember ;
17:34:05,140 INFO blivet: got format: existing mdmember
17:34:05,143 DEBUG blivet:            DeviceTree.handleUdevMDMemberFormat: type: mdmember ; name: sda ;
17:34:05,162 DEBUG blivet:             DeviceTree.getDeviceByUuid: hidden: False ; uuid: None ; incomplete: True ;
17:34:05,164 DEBUG blivet:             DeviceTree.getDeviceByUuid returned None
17:34:05,164 ERR blivet: failed to determine name for the md array e0fb362e-9865-d1c0-cdb0-f5e327c9a085

and the problem behind that is that this:
17:34:05,153 INFO program: Running [5] mdadm --examine --brief /dev/sda ...
17:34:05,160 INFO program: stdout[5]: ARRAY metadata=imsm UUID=e0fb362e:9865d1c0:cdb0f5e3:27c9a085
ARRAY /dev/md/Volume0 container=e0fb362e:9865d1c0:cdb0f5e3:27c9a085 member=0 UUID=1d1335e9:79d4be6a:e16b7fa7:fe8c41f6

in case of a SW MD RAID array starts with 'ARRAY /dev/md/something' which libblockdev uses to determine the name of the device (and so used to do blivet earlier).

I cannot imagine how this worked before, but if this works with F22 Alpha (no libblockdev), we need to investigate it more. Otherwise libblockdev can just search for the 'ARRAY /dev/md/something' pattern in the whole output to get the name.
Comment 18 Adam Williamson 2015-03-31 20:35:26 UTC 
The last time I know for sure it worked was 21 Final. I'll check 22 Alpha later and attach logs if it works.
Comment 19 Vratislav Podzimek 2015-04-02 13:28:18 UTC 
So with some changes in libblockdev (I hesitate to call them fixes now) [1] we get to bug #1208536.

Comment 20 Vratislav Podzimek 2015-04-02 14:29:48 UTC 
Pull request with the libblockdev changes:
https://github.com/rhinstaller/libblockdev/pull/7
Comment 21 Adam Williamson 2015-04-02 16:05:58 UTC 
re-assigning to libblockdev for clarity.
Comment 22 Adam Williamson 2015-04-02 20:14:17 UTC 
Booting TC6 with the updates.img from #c19 I do indeed get to #1208536 , but if I build current libblockdev package plus https://github.com/rhinstaller/libblockdev/pull/7.patch and include that libblockdev build in a boot.iso , I still get 'malformed or invalid UUID'. I think some fix from the updates.img must be missing from the PR.

As explained in the PR, the change related to UUIDs was already pushed to master and thus is not part of the PR (I considered the change safe and clearly right).
Comment 24 Adam Williamson 2015-04-03 06:55:59 UTC 
oh, sorry, missed that. it made testing a bit tricky as there isn't an image with those changes :) i figured out a way, though.
Comment 25 Fedora Update System 2015-04-07 19:44:07 UTC 
libblockdev-0.9-1.fc22, python-blivet-1.0.7-1.fc22, anaconda-22.20.9-1.fc22 has been submitted as an update for Fedora 22.

Comment 26 Adam Williamson 2015-04-07 20:54:24 UTC 
Fix verified with a test image built with the bits from #c25.
Comment 27 David Shea 2015-04-07 20:55:42 UTC 
*** Bug 1209263 has been marked as a duplicate of this bug. ***
Comment 28 Adam Williamson 2015-04-14 21:06:36 UTC 
Update has gone stable, closing (I'll verify FW RAID with Beta RC2 soon).
