personally, I don't see any point to worrying about the default,
compile-time or boot time:
for f in `find /sys/block/* -name scheduler`; do echo cfq $f; done
I tested this case:
- reboot as per power failure (RAID goes dirty)
- RAID start resyncing as soon as the kernel assemble it

Q: Sometimes when a RAID volume is resyncing, the system seems to

A: This is not strictly related to Linux RAID, this

From the command line you can see which schedulers are supported
and change it on the fly (remember to do it for each RAID disk):
# cat /sys/block/hda/queue/scheduler
noop [anticipatory] deadline cfq
# echo cfq /sys/block/hda/queue/scheduler

There's much easier/simpler way to set default scheduler. As

I agree -- if you're talking about changing the io
