Raid 4/5 ???
I'm using Red Hat and trying to get my system (Alienware laptop) to boot up from a software RAID. It works on RHEL 5.3, running kernel 2.6.18-128. It looks like the difference between this version and my non-working version (184.108.40.206) are the modules dm-mem-cache.ko, dm-region_hash.ko, dm-message.ko, and dm-raid45.ko are missing from /usr/src/linux-220.127.116.11/drivers/md/.
I have 18.104.22.168 running on Suse EL 11, and these files are in the appropriate directory (that machine, a Colfax server, is not booting from the RAID, so I don't have to worry about the same issue). When I compare the menuconfig options for each of these kernels, the 2 that are working successfully have an option for 'RAID 4/5 target,' while the other does not. How do I get that to be an option?
Any help is appreciated! Thanks!
