Has anyone successfully build pnfs enabled nfs utils under Fedora 13?
I am running the kernel from:
http://steved.fedorapeople.org/repos/pnfs/13/x86_64/

I installed libtirpc{,-devel}, tcp_wrappers{,-devel}, libevent{,-devel},
nfs-utils-lib{,-devel},
libgssglue{,-devel}, libblkid{,-devel}, and libcap{,-devel}

per instructions from:
_http://wiki.linux-nfs.org/wiki/index.php/Configuring_pNFS/spnfsd#Kernel_and_nfs-utils_compilati__on_
<http://wiki.linux-nfs.org/wiki/index.php/Configuring_pNFS/spnfsd#Kernel_and_nfs-utils_compilation>

I used libnfsidmap{,-devel} bundled in:
Nfs-utils-lib-devel-1.1.5-1.fc13.X86_64.rpm

Finally, I downloaded _nfs-utils-1.2.2-4.1.pnfs.src.rpm_
<http://steved.fedorapeople.org/repos/pnfs/13/source/nfs-utils-1.2.2-4.1.pnfs.src.rpm>
from _http://steved.fedorapeople.org/repos/pnfs/13/source/_

I am having trouble building these utils. I failed to generate
?configure? when I ran autogen.sh:

/c//leaning up ............. done
//lobotomize//: putting auxiliary files in `.'.
libtoolize: copying file `./ltmain.sh'

I deleted the two Makefile.in requirements from line 421 in configure.ac
because there were only python scripts inside those directories.

When I ran the ?configure? generated after the modification, it failed
with the following output:

Yes I think I had that to, on FC12 did you also install tcp_wrappers-devel

[What configure does is look for the tcpd.h file.
So basically you:
- Look in configure what failed, and analyse what was missing here it was
"#include <tcpd.h>".
- yum provides "*/tcpd.h" - will show the tcp_wrappers-devel

Imagine that stupid me, I attempted to configure without reading the wiki first
and had about 10 of these, by the time I gut to libwrap it was becoming routine

RANT: I wish configure would leave the failing code on disk and specify the commands
I need to do to run the failing test. Or at least save and print the gcc output
of the failing test, rrrr ...

You might want to think about installing the yum repo at

Here is the list of packages that need to be installed to
build the Fedora nfs-utils:

libgssglue-devel

libevent-devel

libcap-devel

nfs-utils-lib-devel

libtirpc-devel

libblkid-devel

openldap-devel

krb5-devel

tcp_wrappers-devel


To install these all at once, cat them into a file and then:

yum install `cat /tmp/list`

Next run the following commands:

./autogen.sh && ./configure && make

Hi Benny,

I installed Steve's fedora 13 pnfs kernel and your pnfs utils from the git tree on my 3 node testbed, a client, a MDS and a DS. I have successfully configured and mounted pNFS from the client, but can only create empty files in the directory. All attempts to write resulted in remote I/O errors. I discovered later that spnfsd is not running on the MDS. It dies silently every time I tried to start it. Running spnfsd with gdb indicated that it is reading /etc/spnfsd.conf correctly but crashed while writing to /proc/fs/spnfs/config. Your help will be appreciated?

Thanks in advance,
Helen

Yes... I have the following set,

This performance level seems unacceptable and something must have went wrong.
Were you able to get the 400 MB/s over NFSv4.1 to the MDS?
