Striped LVM on RAID5 is a nice, flexable way to go.
If you set the individual raid stripes at an I/O page
(normally 4K on linux) and then stripe across the
PV's the I/O gets spread nicely across plenty of paths.
Using a stripe == I/O size avoids the "write penalty" in
RAID5, the Raid Controller and drives do a nice job of
buffering and the whole thing should work nicely.

My only comment is that my new setup (specs below) has worked nicely on a
production machine for about a month now.
LVM 1.0.1-rc4
3Ware 7410 RAID Controller
2x IBM 60GB hard drives
XFS Filesystem
RedHat 7.2

Do you recommend any particular kernel release?
Where could I find good instructions on putting it all together?
Thank You,

When I went to 3ware for 7800 driver for SuSE I didn't find one for that
particular release. I found one for SuSE 7.0 and wonder if I could use that
one for my SuSE 7.3 system.

I think I found an reply to an old message from me that states it would work
just fine. How do you like the 7410?

It's the 3w-xxxx kernel module. It seems to be standard in the 2.4.x series
kernels, I didn't have to do any compiling to get it to work. I don't know
what kernel the SuSE distros use though.
The 7410 works nicely. I only planned to do RAID1, so I didn't go for the
extra cache 7450. The only thing I don't like about it so far is the RAID
manager tool that you get from 3ware has a really terribly installation script
(let's figure out which distro I'm running on based on the kernel version I'm
running... yeah! <G>) So I haven't installed it yet. It's also looking like
they only have a GUI tool, which means it'll be difficult getting a monitor
setup to watch for failed disks. :(

I don't understand. Are you saying the all the software I need is contained
within my kernel or do I still need to get a driver from 3Ware?
I'm running SuSE Mantel 2.4.18 which the changes text states it has
2.4.19-pre1 as well as XFS.

I'd recommend ext3 with data journalling for sensitive
filesystems. Its slower than XFS but (seems to) scale better with
striping and large files. XFS performance (seems to) fall off
very rapidly as file size exceeds buffer size.
XFS only journals metadata. So on event of a crash,
the filesystem structure will (likely) be sound, but theres
no guarantee that the data blocks will be uncorrupted!!!
XFS is very nice tho, in that volumes and filesystems can
be grown with no downtime at all (without even unmounting).
You might want to do some benchmarking before committing
to a build (thats recently saved my butt actually).

It was recommended to me that all large file systems have best performance
with XFS.

I've only got a couple of things to say in the regard about XFS and
performance Falling off.
XFS's performance doesn't fall off in the respects you've spoken about.
It's a misconception when using LVM, or evms, etc along with XFS.
I ran into a similar issue, and was convinced it was XFS or LVM, etc.
This is in the relation of using XFS and LVM, vs. XFS with no LVM, and
then testing increasing filesizes with iozone.
What I found was that dbench, and iozone both did not perform very well
with respect to software raid or striping, but that in fact the
filesystems themselves performed about 100% faster than without LVM
striping or LVM Concat.
So much faster that my database guys noticed the enourmous increase in
speed on a test setup I created for them. One was using LVM, one was
not, with XFS. The one which was NOT using LVM had a hardware stripe
setup with write-back caching and adaptive read-ahead. The controller
has 128MB pc100Dimm. Using a 3 drive RAID 0 hardware, vs 3 drives
striped with LVM was an enourmous downgrade when benchmarking..but
actual use, db inserts, file create, etc, ran >100% faster than with
Hardware striping.
I did the same test with Reiser and Ext2/3, none fared as well, but they
all did better with LVM and striping than without.

Well, thats possible. The best thing to do is run
benchmarks (I like iozone) on the proposed
system and see what works best.
The tests I did were just on small filesystems (1G volumes,
64M, 128M and 196M RAM). Filesizes I tested were only
up to 500M or so.
I found that while most tested filesystems (reiser, XFS,
ext3 and vfat) did drop off in performance as filesize
increased, XFS dropped off the most rapidly in that
dimension. ext3 was the most stable (in performance as filesize
increased), though its small filesize performance was the worst.
XFS looked like kinda the opposite!
:)
Reiser had the worst write performance of all of them,
but admirable read.
YMMV.

Hmm..that could be so, but I'm not sure if it's JUST xfs or if it's
XFS/LVM. My largefile performance is excellent, as is my small file
perfromance.

Fair enough; I have to admit that I did *no* benchmarking
of a simple partitioned filesystem, only LVM.
Its so *easy* to just make a new volume for benchmarking
:)
I was lazy... my bad!

Wooohoo!! That's for sure.
BTW..are you using IDE or SCSI?
That is an ENOURMOUS difference, I've found, to LVM/XFS performance
Benchmarking.

My benchmarking was done on IDE, with an offboard
controller and 4 drives as masters.
There should be some more info in the list archive;
I posted some burble here not long ago,
describing just what I was doing. I described it
as 'poor mans RAID'.

I'm using ReiserFS and ext3 (both in production), and am about to move

IMHO, don't use SuSE, pick one of the real RPM based distributions.
If you want everything provided go for RedHat or Mandrake, if you want a
real server (and know how to compile your kernel) go for trustix.
Some more comments:
- don't use striping on RAID5. It is not going to work (well, if you
have two RAID5 sets it will, but that's a waste of disk space)
- this ony appiles to my bad expirience with the 6xxx 3ware controllers:
test wether softRAID with the linux kernel is not faster than the
hardware RAID
(well, you can not boot from softRAID as comfortable as you can from
hardware RAID)
- install the 3ware tool, the 3dm is a deamon that is configurateable
from a web page (only runs on localhost, and has (for sure) some
security holes). It can send mails on errors, too.
(AFAIR the install script is realy broken, don't run it, do it by
hand)
- with a 2.4.xx kernel you do not need a special driver
- I've a 6800 for sale. i switched my home filebase over to 3 promise
controllers. They can do powersaving while I'm at work.

Goetz.

Well, I know that it's november for ever (since AOL did connect to the
internet, usenet actually).
But people, please learn to quote.
It was impossible to figure out WHAT you where refering, too.
see e.g. http://www.inet.bg/faq/netiquete.html

Sorry, please keep up the good work with LVM,

Why don't you think that SuSE isn't a real server OS???

I have 4x40GB Maxtor drives and haven't determined what my final
configuration will be.

It was just MHO, use what ever you're comfortable with, but see my

As others have said, do some test runs.

It's in the tools package you can download from the 3ware side (last I
checked the side required javascipt, so I can/will not look it up for you)

When I installed the SGI 1.0.2 kernel on my machine (2.4.9), it already
had the latest (1.02.00.008) 3w-xxxx module in place. I doubt the SGI
folks added it, so I'm assuming it's a standard module in the 2.4.x
series kernels.
If you want the "manager" software (which really just lets you see
status/configuration), that's a seperate piece you can download.
