[BProc] more questions

[Jack N. <jj...@pa...>]

Folks,

I've gotten a but further but I've hit some other things I need to
figure out.  

Nodes are booting and getting into phase 2 right where bpslave is
executed.  (bpslave -d -i -c /rootfs -p 10001 192.168.1.10)  Which
returns with "Error getting file cache FD: Invalid argument".  So, I'm
thinking that the node is having problems loading libraries or kernel
modules or the like.  

I haven't patched glibc yet.  (Hoping to avoid that but...)  Also, I
don't seem to have the patch for modutils mentioned in the docs on the
BProc web site.  Is one of these the source of my problem?

FYI, bproc_common.h isn't getting installed in the bproc.spec file.
Needs to be added to the %files section.

Thanks!
Jack Neely

You most definatly are running into a problem where the loader from glibc is
not patched, (it's not nescessary to patch the whole of glibc only patching the
loader is sufficient). Also patching modutils is required if you want to load
modules ;)

The company I am working for Hard Data Ltd. http://www.harddata.com is aboput
to relase updated bproc packages and support for Red Hat 7.3 (i686/athlon) and
updated packages for Red Hat 7.2 (alpha/alphaev6/alphaev67) within the next
couple of days.. actually as soon as I find some web space and places to put a
bug tracking/support pages and the like. We haven't totally agreed on using
sourceforge or not.

I sounds like you got BProc built w/o file cache support built in.
Make sure FILEREQ:=y is in Makefile.conf.  (See the release notes.)
If you're still not getting it, then it sounds like I screwed up
somewehere.

You will need that.  You can grab a patched (but somewhat old) library
off www.clustermatic.org if you don't feel like rebuilding it.

Well, I got a new glibc built with the bproc patches but still am not
getting any further.  I do have things compiled with FILEREQ:=y in the
Makefile.conf.  I've also checked to make sure I've got all the stuff
compiled into my kernel that's on the docs on sourceforge.

I've not tried a patched modutils package yet.  I've looked at the older
package at Clustermatic.  I'll have to port it forward but doesn't look
too difficult.

If there's any info I can provide please ask.

Oh if you patched the "Red Hat" kernel with the Bproc patch and tried to make
it work.. you will run into scheduler problems there is issues with bproc vs.
the O(1) scheduler inside the Red Hat kernel.

Re: [BProc] more questions

[Jack N. <jj...@pa...>]

Heh...no...I'm using stock 2.4.19 compiled in a rather Red Hat-ish
fashion.  (This will end up as part of a kit that overlays Red Hat Linux
7.3.)

The RPMsI'm building can be found at

        ftp://rk-devel.pams.ncsu.edu/ncsubeo/7.3

They are desinged to overlay our kit that is at

        http://www.linux.ncsu.edu/realmkit

Thanks!

Re: [BProc] more questions

[Jack N. <jj...@pa...>]

Replying to my own message...

I've been able to forward port modutils.  The RPMs and SRPM are on
rk-devel with the other stuff.  Does it work?  Heck if I know.

I've installed the new package on my head node, rebuild beoboot and
reinstalled it but I still get the same error on my node.  "Error
getting file cache FD: Invaild argument" as produced by "bpslave -d -i
-c /rootfs -p 10001 192.186.1.10".  If I haven't mentioned before, this
is BProc 3.2.0 and beoboot lanl.1.2.

Thanks for your help!
