Important notes
On phobos, /root/.zshenv now contains
PATH=/usr/heimdal/bin:/usr/afs/bin:$PATH
Building OpenAFS-OSD
To build openafs, kernel headers are recommended to be installed (so configure can detect the local sysname). On SL5, as root do a
yum install kernel-devel
and you're set (for the time being). If there's still no /usr/src/linux:
ln -s /usr/src/kernels/2.6.18-92.1.10.el5-i686 /usr/src/linux
...or whatever directory the kernel source was installed to.
In the openafs-version directory:
mkdir `sys` cd `sys` ../configure --prefix=/usr --libdir=/usr/lib --bindir=/usr/bin --sbindir=/usr/sbin --with-krb5-conf --enable-bitmap-later --enable-bos-restricted-mode --enable-fast-restart --enable-bos-new-config --enable-supergroups --enable-transarc-paths --enable-object-storage --enable-osd-policies
Quick RPM creation
See TestCellSetup/IncludingFileservers.
Enabeling the client
- Manually:
From the source directory copy
src/libafs/MODLOAD-`uname -r`-*/libafs.ko
to
/lib/modules/`uname -r`/kernel/fs/openafs/libafs.ko
depmod
- or
- install appropriate kernel module RPM
- reboot
launch afsd
