Bug 60403 – OpenAFS init script: cache must follow links

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Sensei 2004-08-15 03:23:22 UTC]

The init script for openafs searches only an ext2 partition mounted on /usr/vice/cache. Actually, openafs requires that the /vicepX partitions reside on non-journaled filesystems, but, anyway, if someone wants the cache to be on ext2 partitions, it's mandatory to check whether it is on a non-jouraled partition, not if it's an ext2 mount point.

Usually, the cache as well as the etc directories on /usr/vice are symlinks. I propose a modification for the init script.

Reproducible: Always
Steps to Reproduce:
1. Use a symlink for the afs cache directory


Actual Results:  
No matter if it points to an ext2 partition, the check will always fail.

Expected Results:  
Check whether the cache directory is on an ext2 partiton, checking also symlinks.

The init scripts checks the afs cache over the filesystem, not only as a partition

With this patch, OpenAFS checks whether /usr/vice/cache is mounted or points as
a symlink to an ext2 partition.

There's another issue we should take care of: we must check if the cache is on
a non-journaled partition, not if it's simply an ext2 filesystem.

Hey, openafs runs on journalled filesystems, sure. I think you mess it up a bit.
Currently, openafs on linux can run the server part (i.e. the stuff forked under bosserver) on *any* partition. The fileserver process is on linux to be namei based by default (inode based version isn't available at all). So, I run 1.3.73 on xfs partititon.

With the afsd kernel process, called cache manager, yes it can run safely only on ext2 or ext3.

The check for cache *must* take care of symlinks. I proposed a patch. The cache can reside on a journaled fs, but anyway it's suggested to use ext2, as you can see from the original init script.

I'm not arguing about using ext3, but just allowing symlinks.

OpenAFS needs a developer to take up maintenance.

New ebuilds for openafs 1.2.13 (stable) and 1.3.85 (experimental) are available
for testing.  According to openafs-ml, 1.3.85 is currently undergoing testing so
it can become 1.4rc.

The new init-scripts don't bother with the check where the cache partition is
mounted anymore, it's left as the administrator's responsibility (choose
symlink, ext2/ext3, dedicated/non-dedicated partition as you like)...

It'd be great if the new proposed ebuilds could be tested

[Comment 6 Stefaan De Roeck (RETIRED) 2005-08-16 06:45:30 UTC]

The check for an ext2 partition as a cache has been obsoleted.  Hence the
problem will not appear anymore.
