We run a pool full of mirror pairs so we'd add more pairs. Quite easy and can be done while online. The stripe width dynamically adjusts to needs and what disks are in the pool. There is also no need to determine inode settings, as the metadata is dynamic and uses empty space in the pool. As long as you have space in the pool, there is no limit on number of files. So far as I have looked, what tuneable parameters there are can all be done while hot. We use the compression feature on our mail pool which gains us 1.28x the space for a little more CPU usage. Also we keep 14 daily of snapshots in the pool so recovering a users mailbox usually doesn't involve going to tape. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
