Občasno sem tudi admin, ki skrbi za nekaj strežnikov na katerih teče operacijski sistem Fedora Core, trenutno verzija 9. Imam linux (software) raid. Na vseh strežnikih imam nastavljeno avtomatsko posodabljanje preko YUM-a. Problem se je začel pojavljati na nekaterih strežnikih po nadgradnji iz verzije 8 v 9. Nadgradnje sem izvedel preko interneta in ni bilo problemov. Čez nekaj časa pa sem v logih zasledil sledečo napako pri nadgradnji kernela:
grubby fatal error: unable to find a suitable template
Poskusil sem namestiti kernel preko RPM-ja in dobil enako sporočilo o napaki. Preveril sem grub.conf in ugotovil, da potrebnih vrstic za zagon z novim kernelom, ni vpisanih.
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd1,0)
# kernel /boot/vmlinuz-version ro root=/dev/md0
# initrd /boot/initrd-version.img
#boot=/dev/md0

Building a new DOS disklabel with disk identifier 0x1c05d888.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won’t be recoverable.
The number of cylinders for this disk is set to 1279136.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help):
Enako oppozorilo dobim za md1 in md2. Obstoječi kernel (2.6.24.4-64.fc8) se normalno zažene. Je možno, da je do kakšne napake prišlo pri nadgradnji iz fc8 na fc9? V čem je problem?
