Reiser until recently... it's been fixed now.
Do you have a pointer (URL) to any original statement of RAID/reiserfs authors
stating that "it is fixed now" ?
I´m asking because I did not read any statement of them yet -
I have a system 4 with promise ide controllers as well as the two onboard
controllers with one disk on each channel. I haven't tested performance for
the 2.2.16 kernels, however 2.2.14 had poor write performance if there
was a disk on both the controllers on a single card.

Are you sure... I am asking because in their FAQ they still say :
Can I use ReiserFS with software RAID.
Not with raid5, our journaling and their raid code
Does this latest rpm kernel contain the raid-2.2.16-A0 patch?
I tried applying the patch but it failed miserably with

The same patch applied to the 2.2.16 tar ball perfectly.
Is there another patch I should apply?

Assuming you mean "add a new disk to expand the size of the array",

1) backup the data
2) remove and

What's that? 2.2.16-B2? It has not been announced, AFAIK. Where's the
difference between it and A0?

does anyone know, if it is possible to run more than two ide

Sure, apply the linux-ide patch found on kernel.org

Please excuse a clueless newbie question here,
but if you've got a journaling filesystem, wouldn't you want to expose the
raw disks to it so it can choose to put the journals on different disks
than the files?
This would not only help with performance, but it would also make recovery
as simple
I just read that message from James Manning on some performance tuning, and
it made me think about this. On some of our RAID controllers, they collect
statistics for the RAID volumes. The one that I'm thinking of collects
things like this, except that I've trimmed some of the irrelevant
