Subject: Abysmal write performance on HW RAID5
In the process of upgrading my RAID5 array, I've run into a brick wall
(
4MB/sec avg write
I would be very interested to hear how that card works or other suggestions
discussions too.
I have a 10 disk RAID 6 all inside a large case, using on board MB SATA and a
couple 4 port PCI SATA cards. For one, my PCI bus is saturated and a bottle
neck and it is a bit of a pain to replace
I used this site to bring my existing Linux install to a RAID 1. It worked
great for me.

Due too the nature of the data I am storing RAID-6 is not really worth the
extra safety and security, though it would be if I

SuSe uses its own version of cron which is different then everything else I
have seen, and the documentation is horrible. However they provide a

Why do I use RAID6? For the extra redundancy
I've been thinking about RAID6 too, having been bitten a couple of times

Ahh... guess it's time to upgrade again My plan was to start off with 3
drives in a RAID5, and slowly grow it up to maybe
to be able to convert to RAID6 with the same 12 drives even if they
are not full of data.
But that is just my guess on a feature that does not even exist yet...

Last I check expanding drives (reshaping the RAID) in a raid set within Windows
is not supported.
Significant size is relative I guess, but 4-8 terabytes will not be a problem
in either OS.
I run a RAID 6 (Windows does not support this either last I checked). I
started out with 5 drives
Sometimes people confuse Bus speed with actually drive speeds. Manufactures do
it as a marketing ploy. There is the physical limitation for the internal
drive with a sustained read/write speed. Higher RPMs help. Perpendicular
technologies will too as more information passes the head in each
Short answer, yep, I have done it.
I don't know exactly what you are looking for, or what tools you need.

I have used lv with my past raid sets and it is very nice, adds some
flexibility.
I have also done a RAID5 reshape that was in an lv. Unfortunately, at the time
I had an older LVM version that did not support pvresize. So I was stuck with
a larger RAID set and my lv would not take
As I understand it, reshape for RAID6 is coming now. It is in the 2.6.21
kernel still at rc4 as of today though. I am looking forward to it, and plan
to give it a test run when it released.
