Thanks for this Neil, good to know that most of what I would like is
already available. I think your reply highlights what I almost put in
there as my first priority: documentation, specifically a HOWTO.

All this discussion has led me to wonder if we users of linux RAID have
a clear consensus of what our priorities are, ie what are the things we
really want to see soon as opposed to the many things that would be nice
but not worth delaying the important things for. FWIW, here are mine, in
order alt

We don't necessarily expect a diplomatic way, but a clear and
intelligent one would be helpful.
In two-disk RAID5 which is it?
1) The 'parity bit' is the same as the datum.
2) The parity bit is the complement of the
Your error output looks just like what I got on my screen when I just
removed the disk. Did you try removing it from the arrays first?
Basically warm-swap. Google suggests one or two people have tried it.

I am testing a machine with two SATA drives in startech.com removable
caddies. Everything including swap is RAID1. (I'm running x86_64
Scientific Linux 4.2, a RedHat enterprise clone.)
Informal tests suggest that pulling out an active disk causes the whole
machine to hang up but removing a disk fr
I'm about to create a RAID1 file system and a strange thought occurs to
me: if I create a two-disk RAID5 array then I can grow it later by the
simple expedient of adding a third disk and hence doubling its size.
Is there any real down-side to this, such as performance? Alternatively
is it likely t
A much nicer way to get that sort of reliability would be for RAID6 to
periodically scan the blocks on the device and to use the extra
information to do ECC (and for RAID5 to at tell syslog).
