Installing AFS on Solaris 9

AFS Kernel Modifications

The modifications that allow the AFS Cache Manager to function need to be incorporated into the kernel. These instructions are for using the dynamic kernel loader "modload" provided by Sun Microsystems. To incorporate them:

Verify that the modload binary is available on local disk

ls /usr/sbin/modload

Check contents of /usr/vice/etc/modload

This directory should contain binaries for both 32 and 64-bit solaris kernels. You should get something that looks like:

ls /usr/vice/etc/modload
libafs.nonfs.o     libafs64.nonfs.o

Create Solaris kernel extension file

Create the appropriate kernel extension file for your version of the operating system. To tell whether you are running a 32 or 64-bit kernel, run "isainfo -b".

• for 32-bit kernels

cp /usr/vice/etc/modload/libafs.nonfs.o /kernel/fs/afs

• for 64-bit kernels

cp /usr/vice/etc/modload/libafs64.nonfs.o
/kernel/fs/sparcv9/afs

Edit /etc/name_to_sysnum

Add the following line:

afs                     65

so that the resulting file looks like:

...
ulimit                  63
afs                     65
rmdir                   79
mkdir                   80
...

Reboot your machine

/usr/sbin/reboot

Dynamically load AFS into the kernel

The first time you reboot, you'll have to dynamically load the kernel module. After that, this step won't be needed on reboots. To load it:

• for 32-bit kernels

umask 022
/usr/sbin/modload /kernel/fs/afs

• for 64-bit kernels

umask 022
/usr/sbin/modload /kernel/fs/sparcv9/afs

Verify that AFS loaded correctly

The command to check this on Solaris is modinfo, which should return something that looks like this (the numbers don't matter, but the existence of the entries is important):

# /usr/sbin/modinfo | grep afs
101 102754f0  5f782  73   1  afs (afs syscall interface)
101 102754f0  5f782  18   1  afs (afs filesystem)

Install the init script

Solaris needs to find the init script in two locations:

cp /usr/vice/etc/afs.rc /etc/init.d/afs
chmod 555 /etc/init.d/afs
ln -s /etc/init.d/afs /etc/rc3.d/S09afs
ln -s /etc/init.d/afs /etc/rc2.d/K66afs

Return to the AFS Install Guide to set up your AFS cache and finish the installation.
