I am trying to find any statistics on the amount of time doing a upgrade from one version of ZFS to another. I recently updated my system and my zpool is showing that I need to upgrade it. I have a large pool, around 3 TB divided into 3 - 1 TB LUNS in a zraid configuration. I want to do the upgrade, but I don''t know how long that procedure would take, and if it will take a while I want to be able to schedule the down-time. Most of the documentation that I''ve read doesn''t give any statistics whatsoever, which leads me to believe that either the procedure is relatively quick or people just haven''t kept track of it. Any information would be appreciated. Thanks! This message posted from opensolaris.org

Thanks!The data doesn''t get rewritten on a pool upgrade. All that really happens is that the stored version number in the pool is updated to the new version. This allows the pool to use new features in the higher version numbers. -- Darren J Moffat
