Yet another victim of the lagging documentation! Ingo's messages of 4 Sept
on "HOW TO use the newest RAID stuff..." and 8 Sept on "Re: kernel 2.0.35 &
raid0145-19980905-2.0.35-c" are more useful guides to the latest RAID scheme
than the documentation. Maybe they should be included (with a couple of
modifications to take account of the 0.90 changes) in the raidtools package
until the documentation catches up? Can I also suggest that files like
HOWTO, README and Quickstart.RAID which are probably doing more harm than
good in their current condition either be removed from raidtools or have a
warning added at the top of each file stating that the information is
out-of-date.
Basically, there was nothing wrong with this compilation. raidadd, raidrun
and ckraid are defunct (functions now performed by the kernel, mkraid or
raidstart). raidstop, raidhotadd and raidhotremove, which are now the only
other tools besides mkraid and raidstart, are all symlinks to raidstart
(links created when you do make install). So mkraid and raidstart are the
only executables you need in this version of raidtools.
Briefly, to summarize the steps you need to take:
In raidtools-0.90: ./autogen.sh; make; make install; make install_dev
Create /etc/raidtab (you can base this on raidtab.sample in raidtools-0.90)
mkraid -f /dev/md* (to initialize the RAID devices. Do each md device
separately, don't type md* literally. This destroys all data on constituent
partitions.)
fdisk each disk with partitions which will be included in a RAID device, and
set those partitions to type 0xfe
Use tar to copy whichever bits of the existing filesystem you want to move
to the RAID devices (I assume you want to do this as you were looking at
Root-RAID)
Edit /etc/fstab (or RAID-root/mountpoint/etc/fstab if you are switching to
root-RAID) to indicate mountpoints of RAID devices (remember the kernel
cannot be on a RAID0/4/5 partition, so you will probably want a small
unRAIDed /boot partition for your kernel images)
If you are switching to root-RAID, edit /etc/lilo.conf so that root points
to the RAID device, then run lilo.
Reboot. You should be in business.
Forget about your problems with the earlier versions of raidtools. Seems
like you shouldn't have a problem using the latest version, and as the patch
and raidtools versions are intended to go hand in hand, you don't want to be
trying to build earlier raidtools with the latest patch anyway.

No, thank God. The kernel now handles stopping the md devices at shutdown.
The advice in the ROOT-RAID-HOWTO is almost completely out-of-date. RAID
(root or otherwise) is much simpler now, thanks to Ingo's work.

Don't know much about linuxthreads, but I believe if you are using a
glibc-based distribution, you don't need linuxthreads as threads are already
built into glibc.
