Description Rudolf Kastl 2011-08-22 09:35:10 EDT
Description of problem:
anaconda uses metadata version 0.9 for mdraided /boot instead of 1.2 because of an old limitation of grub1 not beeing able to boot from metadata versions > 0.9. I have verified that this is not the case for grub2 anymore.

Version-Release number of selected component (if applicable):
f16 alpha rc5

How reproducible:

Steps to Reproduce:
1. create an mdraided /boot with raidlevel 1 in anaconda
2. check the metadata version given in the superblock infos
3. see that /boot uses 0.9 whereas all other raidsets get 1.2

Please attach /var/log/anaconda/anaconda.program.log from the system so I can see what exactly was done. Thanks.

Comment 3 Rudolf Kastl 2011-08-22 14:12:28 EDT
mdadm is executed with 1.0 metadata flag... after reboot it did show me 0.9 as version for md0 though as far as i recall. the default version is 1.2. it works for grub2 if grub 1.99 final is beeing used.
Comment 4 David Lehman 2011-08-22 15:18:30 EDT
02:23:39,609 INFO program: Running... mdadm --create /dev/md0 --run --level=1 --raid-devices=2 --metadata=1.0 /dev/sda2 /dev/sdb2
02:23:39,893 ERR program: mdadm: array /dev/md0 started.

We are creating the array with --metadata=1.0. If mdadm is somehow overriding that it is definitely an mdadm bug. It should not be overriding explicitly specified parameters.
