Hi!
I'am new to RAID..
If you have one SCSI adapter(sd) and four drives(sda1,sdb1,sdc1,sdd1), in
a succesion made by SCSI IDs, and suppose after one reboot, the 3rd fail,
then the 4th will be the the 3rd? How wil affect the software raid
personality 5 this double change?
Did miss some

To my knowledge, yes.
Is anybody else interested in seeing 1+0, 5+0, etc?
Personally, I would say that if you're going to go for 5+0 or 5+1, you should
really get HW RAID
Hi Rich,
1) The version of lilo was 0.21-15 (came with Redhat 6.2);
2) /etc/lilo.conf
boot=/dev/md0
default=linux
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz-2.2.14-5.0
label=linux
root=/dev/md0
initrd=/boot/initrd-2.2.14-5.0_raid.img
I did check the ownership and permission of both directories and they are
identical. I installed the newer version and the message seems gone but I
got another problem.

got raid working, got lilo all set up, now how should I set up swap in

I have 2 scsi drives set
Hi
I have a RH6.1 box with two mirrored drives in a RAID1 config.
I am wanting to add a spare disk and would like advice on the correct
procedure for adding it to the existing config.
What I planned was:
1. Bring the system down.
2. Install the spare drive
3. Boot up and edit the /etc/raidtab

Coward :-)
3. Boot up and edit the /etc/raidtab to include the spare drive
That is not needed, but is good practice.
[[ What I do is to dump the PSB info to /etc/raidtab every night ]]
4. fdisk the drive to be identical to the mirror'd

I guess I have a few choices about how to set this up.
1) leave swap as /dev/hda2
2) move swap to /dev/sda2 or /dev/sdb2
3) join sda2 and sdb2 as md2 and put

Whenever I made the same LILO upgrade, I found that I had to forcibly remove
the old LILO first (very carefully) or it would refuse to install itself;
though I got a error message indicating failure. Odd your seeing no output
at all! Have you tried "lilo -v"?

With RAID1 there is little point in adding a "spare disk" - you can just
add another disk to the running array, ie:
You cannot "add" a third to to a two-way RAID1.
You can create a new three-way RAID1 if you want.
But you can't (AFAIK) change the number of disk is the base array.
md0: sda1
Just to set the record straight, no layering of RAID arrays works
with the 2.2patch set.
That's interesting since I have several systems with 1 over 0
including one which is one large partition mirrored as with a pair of
smaller disks in a 0.
Both of these systems seem to work well with

Hi Rich,
I removed the default LILO (came with Redhat 6.2), and then installed the new version
again. It did the same. Here is what I received:
1) lilo -v:
LILO version 21.4-3, Copyright (C) 1992-1998 Werner Almesberger
'lba32' extensions Copyright (C) 1999,2000 John Coffman
2) lilo -v 4:
if you use the 0.90 raid code with permanent superblocks and
autostart the raid code will deal with this gracefully.

Does anybody really want to wait while their swap data is duplicated out to
multiple disks by a CPU that is working to free up memory to run
applications?
Isn't Swapping slow enough already?
Why not simply swap on multiple disks, get Hardware RAID-5 for swap or buy
RAM?
Well, the reason we have our systems set to swap on RAID (we use RAID-1) is
that this improves our robustness. Even if one of our disks dies then the
swap continues to work and the system is still stable. Also, I believe, it
is possible to use a RAID-10 to stripe and mirror and actually improve

Hello, all.
I am not a member of this ML, so please CC to me when you reply.
There are lilo.raid1 patch and lilo-0.21-1.1.patch in lilo-0.21 RPM
and I have a few questions about raid and lilo, is there anyone who
wrote lilo.raid1 patch?
