Hello I am trying to install aufs in slackware64 13.37, for a livecd project. Although installation proceeds without apparent difficulty, the resulting module will not load, for unknown symbols.
I know aufs2 is an older and now unmaintained version, but this is the linux dist & kernel I am using so these are the aufs files that appear to be necessary. Any help with resolving this would be deeply appreciated. The files & procedure used are given below. Kind Regards, Mishma => source files used: aufs2-standalone, from: http://git.c3sl.ufpr.br/gitweb?p=aufs/aufs2-standalone.git;a=shortlog;h=refs/heads/aufs2.2-37 2012-04-28 J. R. Okajima aufs2.2 standalone version for linux-2.6.37 [ aufs2.2-37 ] snapshot d8dde07a7cb60196b4d8df4d6976d379c87cc537 & aufs2-util, from: http://git.c3sl.ufpr.br/gitweb?p=aufs/aufs2-util.git;a=shortlog;h=refs/heads/aufs2.2 2012-04-12 Jayen patch to auroot [ aufs2.2 ] snapshot 6dca494f02448832d52ee60401d8a89fc4e0cd11 => kernel source & headers are virgin from the slackware64-13.37 iso: installpkg ./slackware64/k/kernel-source-2.6.37.6-noarch-2.txz installpkg ./slackware64/d/kernel-headers-2.6.37.6-x86-2.txz => Following the README, for the standalone module installation only, everything appears to work: cd /usr/src/linux patch -p1 < /root/aufs2-standalone/aufs2-base.patch patch -p1 < /root/aufs2-standalone/proc_map.patch patch -p1 < /root/aufs2-standalone/aufs2-standalone.patch => the patches all install cleanly. I have checked the kernel source files & the symbol exports are there. => For example, in fs/namei.c, there is now 'EXPORT_SYMBOL(__lookup_one_len);' from aufs2-standalone.patch => then: make bzImage && make modules && make modules_install && make headers_install cp arch/x86_64/boot/bzImage /boot/vmlinuz_ausf2_2.6.37.6 cp System.map /boot/System.map_aufs2_2.6.37.6 cp .config /boot/config_aufs2_2.6.37.6 cd /boot ln -s vmlinuz_ausf2_2.6.37.6 vmlinuz ln -s System.map_aufs2_2.6.37.6 System.map ln -s config_ausf2_2.6.37.6 config mkinitrd -c -k 2.6.37.6 -m ext2 -f ext2 -r /dev/sda2 lilo reboot => System reboot is successful. cd /root/aufs2-standalone => edit /root/aufs2-standalone/config.mk to include proc_map: CONFIG_AUFS_PROC_MAP = y make (no errors) make install (no errors, depmod succeeds) make install_headers (mistyped in README, read correct syntax in a v.3 aufs) cd /root/aufs2-util make make install => No indications of trouble with any of this. But now trying to use the module produces the problem: modprobe aufs FATAL: Error inserting aufs (/lib/modules/2.6.37.6/extra/aufs.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg ....
