Try Webmin if you're afraid of the cli.

I for one wouldn't want my notifications dependent on a GUI application
running. now, if by 'gui', you really mean a web interface to a
resident management service demon, thats a different story.

For me*mdadm is fine but if I set a server for a friend, relative or client I want to be notified by email if something goes wrong, I*mostly (99.5%) work on windows*so*I don't really know what's out there for Linux. I was very impressed with the performance I*got on CentOS 5.6 using software Raid 10 so I'm looking. Thanks

If the email notification is what you need, this script from this site
might be enough
http://my.sohost.eu/knowledgebase/4/Monitor-Linux-software-RAID-array-with-e-mail-notification.html

Just remember to change the email address accordingly.

There are 3 ways to setup RAID 10 on Linux (mdadm). There are -n2 -f2
and -o2 options (near, far and offset) and best for ordinary use is
far (f2).

Here is some numbers from:
http://blog.jamponi.net/2007/12/some-raid10-performance-numbers.html

# the kernel is 2.6.22.12, openSUSE "default" kernel
# the CPU is an AMD x86-64, x2 3600+ in power-saving mode (1000 MHz)
# the MB is an EPoX MF570SLI which uses the nVidia MCP55 SATA (PCIe)
# the drives are 3 different makes of SATA II, 7200 rpm
# each drive is capable of not more than 75 MiB/s (at best - the
outermost tracks) and closer to 70 MiB/s the

I thought the default setup that you get when you install on raid would
configure it to send email to root about problems (that is, you get an
entry for 'MAILADDR root' in /etc/mdadm.conf and an automatically
started madadm --monitor process). At least I don't remember doing
anything special to get those and there is a line:
# mdadm.conf written out by anaconda
at the top of the file.

So the only thing you should have to do is add an alias for root in
/etc/aliases to have this and the info that logwatch sends periodically
delivered to the address of your choice. Depending on your internet
connection and mail server, you might need some tweaking to make
outbound mail work, but that's a different question.
