New Revision: 237367
URL: http://svn.freebsd.org/changeset/base/237367
Log:
Enable deadlock avoidance code for NFS client.
Hm, since this commit I fail with my nfs installworld/kernel.
I have a builder which installs world/kernel to a nfs mounted directory.
Namely used for cross builds.
Now since this commit I get the following when I install kernel to the
nfs directory:
..
install -o root -g wheel -m 555 zfs.ko.symbols
/netboot/sparc64/boot/kernel
install: /netboot/sparc64/boot/kernel/zfs.ko.symbols: No such file or
directory
*** [_kmodinstall] Error code 71
..
The file is there, a local install of the tree works without problems.
Reverting to r237366 also makes it work again.
The server is a -CURRENT, r237880, The client, -CURRENT too.
How can I help to track down the real issue?
Is it always the same file in the install procedure which causes the
failure ? Even more, is the failure pattern always the same ?
I'd say so yes. When installing a kernel onto a nfs mounted fs then
always (in my cases) the zfs.ko.symbols was the failing pattern.
I tried ppc64 and sparc64 as target. With both it was the above file.
When doing a installworld, it was, also in both cases, ppc64/sparc64,
the cc1 in libexec which failed.
Might be, start with ktrace-ing the whole make invocation, including
the children processes.
Some recipes how to start?
ktrace -o <file on local fs> -i make installkernel
Then kdump and cut the lines around relevant failure.
ktrace -f, right?
I placed the whole kdump here:
http://people.freebsd.org/~andreast/dumped_installkernel.log
It is not clear to me where the failure starts :)
I used buildworld on the NFS-mounted obj/ as the test for the changes.
Here the obj is local, only the src and the destination is on the
nfs/netboot server.
I just finished build on NFS obj/ and did several rounds of installs
for world and kernel into nfs-mounted destdir. It seems I cannot reproduce
this locally.
Ok. I try with an nfs obj too.
Thanks.
Andreas
