i'm working on it. Last week i thought it's almost ready, then i found a
new problem area which then forced me to rewrite the whole code for SMP
I have built a couple of iterations of 2.2.x RAID 1 I've always gotten
rpms from rpmfind.net. The Rawhide 1.0 rpms seem to be built maintained by
Red Hat. The kernel has always had the RAID patches applied. However, I
believe you will have to compile it to include your RAID personality for

James,
Thanks for a (mostly) clean step by step! I used this for an
installation I had and I was fairly pleased with the results. However I
got a little confused by your use of "old" and "new" in steps 4, 6, and
8.
The result was that whenever I rebooted I had to raidhotadd the "failed"
disk.
James,
Thanks.
If you rewrite you recipie, the quote below from you should be stated
somewhere. After I read it I understood the whole thing better.
I used to use RAID-1 before autodetection was built into the kernel
(around 2.0.3x I think), and I think that back then, the raidtab was
read at
Optimizing the md driver for Bonnie, IMHO, is foolishness. Bonnie is a
sequential read/write test and does not produce numbers that mean much
in typical data access patterns. Example: the read_ahead value is bumped
way up (1024), this kills performance when doing more normal accesses.

My problem seemed to precede an application of raidsetfaulty (if I
understand its function), thus:
(1) I removed a disk to simulate disk failure. The RAID did not
notice. (Even doing reads may not make it notice, presumably because
of buffering.)
(2) I did a dd if=/dev/md0 way out of range
Hi Folks,

Hi!
Is there a FAQ and/or archive for this mailinglist?
Majordomo could not find any 'info' or 'index' for this list.
I'm about to set up a number of www-servers with software RAID (5 I
think), but I find the majority of the internet-documents on this
subject very old, often refering to

This all pretty much implies that a new RAID patchset will be required
when 2.2.13 hits the streets.
Sigh. So what do the RAID deities suggest someone use for "production"

I was using raid0 with kernel 2.2.5 just fine. I have upgraded the

not get raid0 to work at
