We have a dedicated server with software RAID1 and one of the disk failed recently. The disk was replaced but after rebuilding the array and rebooting the server freezes with a Kernel Panic message
No filesystem could mount root, tried: reiserfs ext3 ext2 cramfs msdos vfat iso9660 romfs fuseblk xfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(9,1)
The filesystem on both disks is ext4.
It seems the kernel can't load ext4 support.
Is there any way to add ext4 support or do I need to recompile a new kernel again ?
Interesting point that before disk replacement all was fine.
The kernel is a stock kernel bzImage-2.6.34.6-xxxx-grs-ipv6-64 from our provider OVH
Here is the content of my lilo.conf file cat /etc/lilo.conf
