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

All,
I appreciate the amount of play my "newbie" question has
had, and have the feeling we are teetering an inch from an
answer. I've got to leap that inch - the infuriating
alternative is that our whole Linux-RAID development gets
tossed and replaced with antediluvian hardware RAID at

correct me if I'm wrong, but I think the current recipe is patching 2.2.12
with the latest raid alpha patch (for 2.2.11) and when patch complains
about fs.h, tell it to completely skip fs.h since changes to that file are
already in 2.2.12
is there a specific reason the raid patches are in the alp
All,
Well, unmounting our RAID (which is using the disk) is not
acceptable, since there will be a bunch of NFS and Samba
shares hanging off it at all times. So (groan) I guess I do
need the latest and greatest. Can someone point me to the
right recipe for going straight from RedHat 6.0 (2.2.

Didn't understand this. Our system is on hda and we can't
unmount it.

All,
Here's a reprise of this ancient message. But there's method
in my madness. We need to do just this and are hitting a wall.
We have stock RedHat 6.0 with the 18 disk patch by Lance

I've tried this:
Insert 4 disks in system, 1 root, 3 in raid-5.
The raid is up and running.
I remove one of the disks in the raid (yes, they are supposed to
be hot plugable...).
The raid complains, and continues

you hit the nail on the head man. no need to copy things to the replacement
disk. just get the partition table right and readable by linux (requires the
reboot in 5). then use raidhotadd.

I have a follow up question:
I have a Compaq server running Redhat 6.0, with hot-swapable root disks, that
I've set up to use a raid-1 root disk. (by kreating a new bootimage with the
raid-1 loadable module included).
Yesterday one of the two disks included in the raid-1 had some problems.

Hello,
Scenario: IBM server 320, hot-swappable disks, adaptec 2940UW.

I've set up a raid 5 between the non-system disks on this beast.
My question is (this must be a FAQ, I just havn't seen anything about

What do I do when a disk fails? How do I te
