[OpenAFS] Status of OS X 10.6 64bit kernel support ?
Fri, 21 Jan 2011 14:41:55 +0000
Just thought I would ping this report, to see if anyone else has any
other ideas ?
I need to run the 64bit kernel, as have updated my MacBook Pro to 8GB
ram, and I need to run the 64 bit kernel to properly support this. AFS
is so slow it is effectively unusable in this case. I can live without
AFS but it would be very nice to get it usefully working again.
Would this be an appropriate thing to ask on the devel list ?

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.

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.
