after yum update, system no longer boots

This AMD system has been working fine with Fedora 20 for months.

It consists of two identical drives working as RAID 1.

These drives only have 1 partition: the root.

After yesterday's yum update, the system no longer boots. It waits for a long time at startup, and then dies with a dracut error,
"dracut initqueue device uuid not found" (and it shows the UUID of the raid system), and drops me in dracut rescue prompt.

However, when I boot from live F20 USB, it finds the raid system fine, and working -- I see both devices in /proc/mdstat, and I can mount the /dev/md127 just fine.
I even did an fsck -f /dev/md127 and it was fine.

Likewise, if from grub2 menu I pick the third kernel listed (3.14.5-200), that boots the system right up!
So only the newest two grub entries (kernel 3.14.7 and 3.14.8) fail to boot the system.
(Yes; I checked to see what was different about the third entry versus the first two, and only the kernel and initrd version numbers are different)

Note: After some more fiddling, I managed to lose the third kernel as well. Only the "rescue" kernel listed now boots the machine

really odd..

Any ideas what I should be checking?

Many thanks, -turgut

Re: after yum update, system no longer boots

No help here. Love the file name of the screenshot!

Back to the top of the heap.

Oh, by the way, journalctl tell you anything? That log file helpful at all?

Re: after yum update, system no longer boots


I'm still stumped at the same place; 24 hours later.

Nope, journalctl just shows the SAME thing that's on the screen.

Re: after yum update, system no longer boots

My two cents here: RAID1 is more trouble than its worth.. Once/if I recover my data (yeah I hosed my raid array in the process; rebuilding it now I hope) I'm just gonna get rid of it; and replace it with an rsync that runs once a day.

Re: after yum update, system no longer boots

After much struggling with mdadm, dracut, and grub2-mkconfig, I finally got it to work again. No idea if it will survive the next kernel update..
It took two days' work.
I believe at the end it boiled down to several things:
grub2-install to both /dev/sda and /dev/sdb
then dracut with its --mdadmconf option so it reads the /etc/mdadm.conf file..
of course that file needs to be correct..

Here is what the /proc/mdstat looks like:
Personalities : [raid1]
md0 : active raid1 sda2[0] sdb2[2]
971509760 blocks super 1.2 [2/2] [UU]
bitmap: 3/8 pages [12KB], 65536KB chunk

unused devices: <none>
