The system is Fedora 22, recently upgraded from Fedora 21. The remaining kernel from Fedora 21 boots. The two kernels installed after the upgrade fail to boot.
The system is an Intel S-5000 PAL with 5 SATA drives configured in raid 5 array. It has been running without issue for nearly 2 years. And as mentioned above continues to run with out issue with the Fedora 21 kernel.
The issue is with upgraded kernels the boot process hangs and after 3 minutes drops into the emergency shell. The journelctl output shows the following error messages:
systemctl: Starting dracut pre-trigger hook..
lldpad: config file file failed to load,
lldpad: create a new file
lldpad: bound ctrl iface to /com/intel/lldpad
dracut-pre-trigger: dracut-pre-trigger: rd.md=0 removing md raid activation
At the end of the process the error message is:
raidboot /root device not found
The Fedora 21 kernels boot and runs normally. The following has been tried:
- rebuild initramfs
- run grub2-mkconfig and reinstall grub
As further background this server is part of a network of similar servers. The upgrade of the other servers was successful. A comparison of the lsinit output for the two initramfs.img files shows similar output. The only differences are in the area of pre-trigger and lldpad.
Is Pre-Trigger configuration the cause of this? What step is missing to cause dracut-pre-trigger fail in creating initramfs? What packages are required to support pre-trigger? What configuration is involved in pre-trigger? pre-trigger be re-run to support creating initramfs?
