1. switch off HTML mode in your mailer :)
2. check that the device nodes /dev/md0 ... exist
if not create them:

it isn't?? !! So md is totally dependent on the ide or scsi

That'd be a major bug then wouldn't it? If what you sai

Hello.
I've been using RAID for some months with the RAID patch you offer from
pub/linux/damons/raid/alpha
on the kernel mirrors. I use the on boot raid superblock autodetection and I like it
much. I think
it's very good working. However, I like to upgrade my kernel often, and keep it up to

This behavior can be improved, but most probably no bug there.
On the first detected error, we have switched to degraded mode and
*new requests* to the RAID device will not be redirected to the failed
disk drive.
However, in the current architecture *old requests* which have
been submitted to th
I have a running system that I would like to put into raid1. However, what

Hi again,
I was doing further experiments with the described configuration. I added
another scsi-controller (Adaptec 3940 UW) and put one scsi-disk on the
second controller. After pulling the power from one disk, the system
fails in the same way as it fails with one controller: scsi-bus resets
Hello,
I am is facing problem in Raid.
I have created Raid1 on 500Mb partitions on sda5 and sdb5. For testing purpose
i disconnect power
from sdb while copying data to the Raid. But the raid is still trying to
access sdb and then
giving errors and do it in an infinite loop.

After investigating a bit more, it seems that the boot process
prompting for 'root' password is due to the need to patch a
bit the /etc/rc.d/rc.sysinit script. solved.
Now 'raidstart /dev/md0' still refuses to run on 2.0.37 RAID 0.90
patched kernel and the exact returned code message is:
/dev/md0
