Description Phil Anderson 2011-12-25 02:04:28 UTC
I just did a clean install of Fedora 16 on my pc.  Each of the 4 disks were configured:
sda1: 1G Raid-1 (md0: /boot)
sda2: 10GB Raid-5 (md1: LVM /, /var)
sda3: 2GB Swap
sda4: 300GB Raid-0 (md2: LVM /home)

For some reason, md1 had the wrong Array UUID written in mdadm.conf & grub.conf for the raid-5 array hosting the root file system, resulting in an unbootable system.

What further info do you need?

Comment 1 Phil Anderson 2011-12-25 02:08:02 UTC
Also, I'm not sure if it is of interest, but booting in the recovery CD fails to put together my filesystem.  I can manually assemble it with mdadm --scan (after fixing mdadm.conf), vgchange -a y & mount without issue.  Might be related?

Comment 2 Brian Lane 2011-12-30 16:31:56 UTC
Please switch to tty2 (ctrl-alt-f2) and attach the logs from /tmp/*log to this bug as individual plain/text files. Or on the running system you can find them in /var/log/anaconda/

Anaconda logs

Here are the anaconda logs.  I can't remember which UUID it actually put in /etc/mdadm.conf, but I changed it to:
ARRAY /dev/md1 level=raid5 num-devices=4 UUID=53b83e4a:1155fd4f:1858c59f:fca55f1b

Are you able to reproduce on F17?  F16 was long ago :/

Comment 5 Fedora End Of Life 2013-01-16 10:12:47 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 6 Fedora End Of Life 2013-02-13 08:45:22 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
