Hi,
I have found EVMS a good system. It is highly daunting initially
though. Once you get your head round it things like online resizing of
partitions and creation of volumes are nice and easy. If someone is
familiar with it maybe a overview how it works. Personally I find it
really handy but my server has got too big and I am looking at the new
Open Solaris release... which looks very nice. I plan to use ZFS
allowing me to add hard drives at random to increase the pools
storage. I don't care where it puts the data just I only have one
hierarchy to look through.
Either or both of these might be of interest. Open NAS, or SME maybe
too.

I've been following some of the discussion this week about disks
with interest.
I would love to hear a talk about RAID with a demonstration of how
to set up a raid solution.
Questions for consideration:
Can I set up a single volume with a bunch of different sized disks?
What are the names of the tools for setting up RAID? (One of the
biggest battles with setting something new up is knowing what the
tools are called so you can do your research with man.)
What tools do you use to monitor the health of a disk? Disks have a
thing called SMART, what is it? How do we use it?
Can you tell/show us different RAID 5 configurations?
How do you add another disk to a RAID solution without having to
rebuild the whole thing from scratch?
Can you use USB devices in a RAID solution?
Consider this... I might set up a small server with a 100gb disk
which has 2 usb ports on it then copy all my movies to it. Next
year the price of disks comes down and I've saved some money and
I've got more movies. Can I get a couple of external drives and
plug them in to the USB? (So I'm up to 1.1TB)
Next I get a couple more external drives, so I unplug one of my USB
drives and connect a small USB hub and plug in the 3 drives into that.
Can I keep growing my small servers disk system this way?
Cheers Don
