Not without more information. The state information is stored per
callback, which is one per file/directory in a writable volume, and
one per entire readonly volume, so without knowing what the client's

Thanks Derrick,
So basically, its one callback state per file and one per RO volume. I'm
assuming that the server with the RO volume will not be maintaining the
state of the server with open files and likewise the server with open files
will not be mainataining the state of the RO volumes.
So,
Gary:
A volume can either be read/write or readonly. Only one file server
can maintain a copy of the read/write volume but multiple file servers
can maintain a copy of the readonly volume.
Callback state is not shared between servers. The callback
registrations are promises by the file server
Hi,
Is there a place I can find the current file, directory, volume and
partition limits for OpenAfs ? I'm not sure which values are current.
This is what I found searching:
Max Number of Volumes Per Server: ?
Max partition size in 1.4.x is 2TB
Max partition size in 1.5.x is max signed int64

Thanks so much !!!
I'm evaluating different distributed file systems for a cloud file

Yes, I said it, cloud.
I've always admired the Andrew concept from the early/mid 80's.
I like that AFS doesn't attempt to wide stripe data across servers. This
company's model, they have lots of
