I've discovered that my dedicated cache volume was originally setup with
64k block size and suballocation enabled (compression is off). We keep
getting 'cache volume out of disk space'popup messages on all the clients
which I think may be attributed to the above. Is this likely to be the
case?

If so, how easy and safe is it to delete the cache vol and re-create with
8k block and no compression or sub-allocation. What should the procedure
be?

Thanks
