Key Decisions
- OpenAFS 1.4.6 is not very different from the 1.4.1 software release, and 1.4.5 in production use by Athena. Only testing of the installer and of basic operation is necessary.
- We are changing the installer methodology to use the new yum-based installer supplied by OpenAFS.org.
- sysname Conventions are the same as with 1.4.1:
- sysname will be set to the value
shipped by default by OpenAFS.org, rather than
the special values that Athena has
adopted.
- For each RHEL sub-platform a pathname
compatiblity mapping will be maintained in the same place that we
currently maintain module version and platform mappings. Our
installer init and boot-time refresh scripts will keep it in
synch.
- non-Athena "add" will behave as closely as
possible like Athena "add". This means add will iterate over the
pathname compatibility mapping and put the first one found in the
PATH. In practice this might look like:
i386_rhel5:i386_rhel4:i386_rhel3: etc..
- We will need to define names into
existence for 64 bit platforms, non-i386 platforms, non-rhel platforms
(such as SuSE and Fedora).
- 12/20/07 To simplify the release process: We will freeze RHEL 4 at OpenAFS 1.4.1, and offer 1.4.6 as RHEL 5 only. This minimizes the effort to deal with how 1.4.6 has a new yum-based update system that doesn't work under RHEL 4.
- 5/13/08 Having released 1.4.6, we se no compelling need to update to the recently released 1.4.7.
Notable Features
Support for Red Hat Enterprise 5.
Significant bug fixes and enhancements to reliability,
stability, and performance.
Fixes the issue that 1.4.1 had with cache partitions of 8GB and larger.
System
Requirements
- Computer/Processor: Intel Pentium III or faster processor (Pentium IV or better recommended)
- Operating System: Red Hat Enterprise 5
- Memory: 256 M
- Additional requirements:
- Kerberos including the mit-krb-config RPM.
Testing
OpenAFS on Linux Test Plan Accepted 11/6/03
Known
Issues
- AFS caches larger than 8 GB are now working.
- The athena-like sysname will be i386_rhel5.
- add and attach are not the full Athena attach commands.
- Sometimes the script to do the initial AFS setup aborts because yum-updatesd is running.
