If this comes to pass, I may end up making an effort to get it working on FreeBSD as a hobby during my spare time. Some things to look at that I've also been poking at: * Apparently the newest development (1.3.x) OpenAFS servers will work on FreeBSD, but the client is not production quality. * /usr/ports/net/arla implements a client that supposedly works on FreeBSD, though I have yet to test it. * OpenAFS is looking for people interested in making their client work on FreeBSD. Hope this helps. I'd like to see FreeBSD get much better AFS and general clustering/internetworking support. For example, easier to configure LDAP and Kerberos. Must.. compete.. with.. Active..

This is something else I've been wanting to look at as well. In general I'd like to see many more file-systems supported in FreeBSD. Not as root devices, necessarily, but general kernel module support for them.

These can have very nasty effects on the filesystem and require extraordinary effort to recover from.

In order to actually get a clean filesystem I have to move aside lost+found and recreate it, and then rerun fsck. This needs to be repeated up to a dozen times until all of the errors are repaired. Recently I decreased KSTACK_PAGES to 3 to see if I could provoke the bug again. I could :) This means that KSTACK_PAGES=4 is necessary to provide reasonable protection against the problem. Please commit this change for 5.4-R, because I'm sure other people in the real world will be able to duplicate my disk load. Also, fsck needs to be fixed to not pretend that the filesystem is clean when it knows it hasn't been able to fix all of the problems because lost+found filled up.

Actually I was looking in the wrong place (NOTES); I still have it set to 4 on this machine. This indicates that even this is only a partial workaround, but at least it only happened once in the last year or more, instead of every few days.
