I have this system that I have been using that was running Fedora 21.
I just updated it today (Monday) to Fedora 22. It is an old Dell
Optiplex GX620 with two 2TB disk drives set up with two partitions
each in a RAID One configuration. LVM2 runs on top of the second
partition with several logical volumes. This system had been running
just fine before I did the upgrade. After the upgrade, the system will
not boot using one of the new Fedora 22 kernels. It boots just fine
using one of the old Fedora 21 kernels that did not get replaced during
the upgrade.
I can get the system up using one of the new kernels, but I have to
wait until it stops at a Dracut prompt. I then manual run "mdadm --
assemble --scan" to get the RAID One partitions assembled, and "lvm
vgchange -a y" to get the Volume Group built. After that, I issue an
"exit" and the system completes the boot process. I need to figure out
why this system will not boot without intervention. Any suggestions
would be appreciated.
I have tried to rebuild the initramfs with dracut, no joy doing that.
Here is some of the data:
