Jiri, It looks like the kernel configure checks are failing badly. You should post your config.log. FYI, you're going to have more trouble than just fixing the config checks -- the pNFS patches for PVFS have not been updated for a long time, and a lot has changed in both pNFS and PVFS. If you're interested in updating the patches, we can try to help you figure out what to do from the PVFS side. -sam > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_gen_credentials’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:26: error: ‘struct > task_struct’ has no member named ‘fsuid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:27: error: ‘struct > task_struct’ has no member named ‘fsgid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_inode_getxattr’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:777: error: ‘struct > task_struct’ has no member named ‘fsuid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:778: error: ‘struct > task_struct’ has no member named ‘fsgid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_inode_removexattr’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1048: error: > ‘XATTR_REPLACE’ undeclared (first use in this function) > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1048: error: (Each > undeclared identifier is reported only once > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1048: error: for each > function it appears in.) > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_create_file’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1221: error: ‘struct > task_struct’ has no member named ‘fsuid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1221: error: ‘struct > task_struct’ has no member named ‘fsgid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_create_dir’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1308: error: ‘struct > task_struct’ has no member named ‘fsuid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1308: error: ‘struct > task_struct’ has no member named ‘fsgid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c: In function > ‘pvfs2_create_symlink’: > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1402: error: ‘struct > task_struct’ has no member named ‘fsuid’ > /root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.c:1402: error: ‘struct > task_struct’ has no member named ‘fsgid’ > make[3]: *** [/root/pvfs-2.8.2/src/kernel/linux-2.6/pvfs2-utils.o] Error 1 > make[2]: *** [_module_/root/pvfs-2.8.2/src/kernel/linux-2.6] Error 2 > make[1]: *** [default] Error 2 > make: *** [just_kmod] Error 2 > > which is exactly the same as was already discussed in the mailing list at > http://www.beowulf-underground.org/pipermail/pvfs2-developers/2010-February/004518.html > (I'm sorry I'm not replying to the original thread, but I don't know how to > do it :() - I'm not sure though whether I got right the advice provided ("Can > you see if pointing pvfs at the the /lib/modules/2.6.32.2/build directory > fixes the problem?") - maybe I'm wrong, but I suppose that means passing the > KBUILD_SRC option when doing "make kmod_install"?
