All, if one has data files on a system disk and one wants to make a zfs volume of those non-OS filesystems, will it take more of a performance hit as a zfs volume or as a regular filesystem or no difference at all Thanks Peter -- Peter Wilk Technical Support Engineer Sun Microsystems, Inc.

Do you have a "non-OS" slice (e.g. "/data" or "/export/home") on a system disk, and you want to convert that slice into a ZFS pool? Or do you already have a ZFS pool, and want to create a ZFS volume within that pool, and then want to put a file system on that volume? Of course it depends on the usage pattern of the data, but I don''t think you''d notice any performance difference either way -- unless you do things like streaming writes approaching the disk bandwidth, etc. Regards -- Volker -- ------------------------------------------------------------------------ Volker A.
