[Tfug] the long awaited file-server

[Robert Hunter]

Harry, after months of trials and tribulations I have this new file
server online.  It took one month to get drives that were properly
packaged ( I ranted about this in a previous post ), then another month
to get a replacement controller ( the first one had dead ports ).  I've
come to the conclusion that HighPoint does not have a technical support
department, and that the number they give out is an alias for /dev/null. 
The operator was no help, and in the end the only way I was able to get
help was by contacting a senior management person, whose email address I
found by googling around.  Incredible!

Anyhow, now the thing is up and running, and I'm a happy camper.  13
disks in RAID-6, plus a spare.  I even setup ethernet bonding with the
dual gigE adapters onboard.  My stats don't quite match what you posted a
while back, Harry, but they are reasonably close.  I ended up using ext3
because I wasn't brave enough to try the "faster" filesystems, such as
xfs, reiser, or ext4 -- I have no desire to face an angry mob of users
with lost data.

Thanks for your help, Harry, and everyone else, whose names I don't
remember right now, but that could be because of the two bottles of beer
I just drank.
