Ben,
Thanks for your suggestions. The system that I was testing with Debian
is a Dell M600 blade and a M100e chassis combo. I believe the Dell
hardware RAID is discribed as a "SAS 6/ir (H/W based) with RAID 0/1
support." As far as I can tell, this Dell particular hardware set up
does not support Debian. The 64 bit Debian installer did not run at
all, and the 32 bit Debian seemed to install but had issues booting up
and recognizing the RAID drives.
Could someone share with me a sampling of the server models for the
systems they are running on Debian or other OSes?
Potentially, I might have to wait to install Evergreen on the Dell
hardware I have with RedHat once Evergreen 2.0 is released. In the
meantime, I will keep running and testing Evergreen 1.6.0 on an old PC.
Finally, any other suggestions or comments on using logical volume
management (LVM) or separate partitions for "/home" , "/usr" , "/
var" , "/tmp"?
Thanks in advance,
Yamil

Hi Yamil,
I'm not an expert on RAID, but I can tell you what we know from our
experiences thus far.
Me personally, when I was brand new working with Linux, I went with
the default options of Debian to get going and seeing what Evergreen
could do.
Long-term though, we've encountered some difficulty dealing with our
hardware RAID (which was actually just a sort of fakeRAID) and
Debian recognizing it properly. For our test systems, I usually
just use a single drive with the default single partition option.
As I understand it, a good reason to use multiple partitions is to
break up the various parts onto different drives for space/backup
control options. You could also skip the hardware RAID and go with
Linux software RAID1 option too and use Debian to mirror your drives.
Maybe someone else might have more insight for you; we're in the
process of reviewing how specific hardware RAID models will work or
not work with Debian operating systems as we plan future hardware.
I'd be curious to hear what you discover with your particular
hardware RAID, could you tell us which one you're using in your
server?
Good luck!

Hello,
This is a question geared for system administrators running
Evergreen, though I am not sure if this is the list I should use.
My library is migrating to Evergreen this month and I am about to
set up a brand new server to house Evergreen. The server has two
300 Gig hard drives with hardware based RAID 1 and 8 Gigs of RAM.
My questions are about Debian partition configurations based on the
choices given to me by the Debian installer.
1) When I install Debian on the new server should I use logical
volume management (LVM)
2) Should I set up...
A) a single partition for the single logical (RAID 1) drive
or
B) a separate "/home" partition
or
C) separate partitions for "/home" , "/usr" , "/var" , "/tmp"
Thank you in advance for your help,
Yamil
