Hello,
I am debugging an issue with our file system which on OS X 10.7 where Finder caches the volume mount information for the size capacity and available bytes of our volume. We are a specialized network mount where "new" mounts can come and go underneath this overall mount. This has the effect of dynamically changing the mount volumes capacity and available space under that "super" mount.
How can I get Finder to purge its information?
When I perform a GetInfo on the mount in the Finder window, I see lots of statfs calls which in turn result in VfsGetattr calls into our driver which return the correct f_bavail and f_bfree fields, and return the updated information from dtruss or fs_usage but still Finder shows the initial quantities. df works correctly and shows the updated information.
How do I cause Finder to update?
Thanks.
Steve
