[OpenAFS] Status of OS X 10.6 64bit kernel support ?

[Chris Jones]

Hi,

It doesn't seem to help. navigating around in afs is just a lot lot =
slower and less responsive when in the 64 bit kernel, compared to the =
same operations when running the 32 bit kernel. Eventually they do work, =
they just take a long long time.

One thing in particular that seems to show the problem is just =
repeatedly running 'ls' in the same AFS directory. With the 32 bit =
kernel the first time I run this (after a reboot) might take a short =
while to complete (presumably whilst the cache is being refreshed) but =
subsequent runs are essentially instantaneous. With the 64 bit kernel =
this is not the case. Each time I run ls in the same dir, it takes the =
same long time (order minutes) to complete.

cheers Chris

However, if I switch to the 64 bit kernel (which I would like to do for =
other reasons) openafs seems to experience problems. Accessing afs =
directories (under /afs/cern.ch, if that matters) seem to just hang up, =
without ever accessing the AFS file system. The same operations using =
the 32 bit kernel do not show these same hang ups. I have searched the =
Console messages, but not spotted anything (to my uneducated eye) that =
relate to afs.
