[OpenAFS] directory corruption with XFS

[John Bleichert]

Hello All

Well I finally got around to rebuilding my / directory. I made a small 3 
GB / directory (which contains /usr and hence my AFS cache) and made the 
rest of the drive XFS. Now, with my AFS cache on an ext2 filesystem, I'm 
not seeing any of the directory listing corruption I was before.

I can;t give you any more detail than to say that you're right, apparently 
the XFS and AFS caching mechanisms were stepping on each other's toes.

All is back to normal now.

Thanks - JB
