1. Important notes

On phobos, /root/.zshenv now contains

PATH=/usr/heimdal/bin:/usr/afs/bin:$PATH 

2. 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

2.1. Quick RPM creation

See TestCellSetup/IncludingFileservers.

3. 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

4. Enabling OSD

[iokaste] ~ # vos setfields osdtestvol2 -osd 1

5. Issues

5.1. Missing token is not handled well

$ osd volumes io -lun 1
RX xdr error
Cannot list volumes
Request aborted.
    
$ osd createv io 1 536870924
Createvolume failed: RXOSD_create_part ended with 13
Request aborted.

In general, missing privileges are an issue but there is no "friendly output" describing the cause of the problem. Some examples of unprivileged access attempts:

Database queries osd listosds and osd servers seem to work unauthenticated.

6. Performance
