If standard SCSI is the limitation, do you know if fiber channel has this
limitation? If I switch to a fiber channel connection between the RAID
and PC, and considering the kernel LBD support, should that allow larger
volumes to be recognized properly?
Thanks,
Randall

I doubt you will have any luck - standard scsi in itsself has a limit of 2TB
(32bit block adressing with 512 byte blocks). LSI (others have followed
since) has new enhancements
(
http://www.infortrend.com/%5CNews%5C20041006%5Cf_64Bit_LBA.htm) but I know
of no storage devices that currently implement that since it is not an
official standard and seems to have some other problems....
Your RAID should not allow you that or at least warn you if it supports the
extension (what model is it?) but I know for sure that the adaptec 7xxx chips
don't. You can try a LSI controller and see what happens or you can create
multiple luns and then raid0 them - that should work for you snce you got
LBD...

While I agree with your theory that it usually is easy to find a
workaround for hardware issues, the basic thrust of the story referenced
was the horrible customer support.
Even a company that produces the best product can be killed by failure
to pay attention to customer support.
I personally may chose (and have done so) a supplier with a slightly
inferior product if their customer support is outstanding, and I wager
many others view it the same.

There is no typo in the config files... they used to work OK and I never
touched them. I have 3 Fedora Core 3 boxes in my workplace and all of
them have the very same problem. One is a high end production web
server and the other two are workstations, one is mine and the other one
is from a coworker who wanted to try linux as his main OS. (BTW, I
checked his yum problem through vncviewer with Gnome 2.8 Remote
Desktop... Cool!!!).
Now, in a yum mailing list I saw that it was due to a router problem
that might be blocking or closing the connection, so it seems not
everybody sees the problem.
At home yum works very well (FC3 box too) but there are lots of pending
updates because I have a dial up line :-(
Thanx for the answer and I hope you can help me.

Oh, I am sure it is too. I have seen it in action in the early days -
getting kicked offline constantly, unable to connect etc etc. As far
as Linspire goes, I haven't used it, but I am not interested. However
if they support a .deb file then I would think that that means greater
support for other .deb type distros- knoppix, regular debian, mepis to
name a few. I guess the question comes down to - 'how much work are
you willing to do ?' Maybe a lot , maybe not much.
Hey, someone needs to create a 'ubiquitous connecting app' -- one that
would allow ANY USER to connect a Linux box, to ANY isp. It could
have a GUI that allows you to pick your isp if it is one of the big
ones, otherwise give servernames and/or ip addresses to connect. The
app could fool the isp into thinking that it is the isp's software.
It could contain a bunch of *very similar* code, to what the isp's
themselves use. This is along the same lines as my earlier post
today, about spoofing stupid websites into thinking that your browser
is whatever they require. THAT might help the Linux movement as well.
[Of course, someone is probably already doing _that_ one as well....]

the "Desktop" XML files are in /usr/share/applications (along with some
other places).........
the "menu" files are in /etc/xdg/menus.....look there for paths where
the "Desktop" XML files are stored...
Look at these files and you should be able to "roll your own".....

LOL.
Linspire (IIRC) is the version used on the machines sold at Sams Club
and Walmart (both online) and at Fry's, all for under $300
It is not likely a mainstream version, and thus they have a specific
targeted "luser" base that does not know how to get anything better.
