BINGO!! you hit it on the head...in /var/log/messages, I have lines containing
md but they show 0.36.6 as the version, not 0.90.0. so, Ill get the
patches from the location you sent me, but I would like instructions on
how to install the patch...

I am trying to use mkraid to setup a software raid array. I have 3 * 4G
drives with a two partitions each. the first partition is a 64 byte
block for an Apple Partition Map, the rest is a unix partition. I have
setup the /etc/raidtab that is attached and when I try mkraid /dev/md0,
it sees each

Linux uses swap intelligently, if areas of memory don't change they get
swapped out to disk, making more physical RAM available for file caching,
etc. Having swap is good even if you have oodles of RAM just for that
reason

is there anybody doing the parity generation by using the
drive XOR cmd (XDWRITE, XDREAD, XDPWRITE) ?
we will start this kind of work in Linux raid,
want to know anybody else is also doing the same thing.
we're looking for cooperation.
Thanks

Hey all,
I've been thinking about this for a different project, how bad would it be
to setup RAID 5 to allow for 2 (or more) failures in an array? Or is this
handled under a different class of RAID (ignoring things like RAID 5 over
mirrored disks and such).
Three words: Net b
a line like 'autodetecting RAID arrays'. If it's
not there, you're not running the patched code.
Something like this would work:
dmesg | grep -i raid
to show you any raid output from boot.

Might double check and make sure those partitions exist as well.

Just get the Alan Cox patches from your favorite kernel.org mirror, a
clean 2.2.13 kernel tree, and apply. No failures, just good clean
raiding.

Ah, I see now. I'll try applying the patch to the

Are there any patches avaiable for this yet?

Hi,
WD tech support is wrong. Ultra-ATA/66 is definitely 66 megabytes per second.
Not 66 megabits. There is ABSOLUTELY NO QUESTION about this.

aftern ten hours I'm reasonably sure it's in a loop. Group is six
28GB partitions, raid-5.
Please copy me with any replies I'm
the performance side, but on the paranoid side,
I use the multiple devices method.
That way, if something goes wrong, I don't _neccessarily_ lose
everything in one fell swoop. YMMV.

I believe he is referring to some fs instability that has happened in
2.2.10, not 2.2.x in general.

As mentioned by Brian, this setup is not likey a valid one. Try
reversing it:
make two raid0 and run them into a raid1. that should work.

1) Did you patch the kenrel before you compiled (2.2.6/2.2.10)?
2) Turn on persistent-superblock (chang 0 -> 1)

a software raid array? If you do it
frequently, the time/cost to learn it amortizes well. Additionally, you
would factor in the cost of learning how to get NT to cope with the
particular hardware choice. How much would this run at ~400$US/call to
MS? (not always neccesary, but frequently).

This one kind of goes aling with learning. Perhaps you are considering,
or
testing it out to see if it works with new kernels, etc..
