I know, I've done some queries in the past... about 70% of the files (number of files in a aggregate is available) in my environment is (was at that time) stored in aggregates smaller than 10 MB. That also accounted for about 12% of total capacity. > Thereafter, that Aggregate is managed and moved around in storage > pools as a clump.

I know that aggregation plays a role, but you can keep things in control with tnxmaxsize. And yes, still then there is no guarantee, but it does help a lot, IMNSHO. > Richard Sims -- Met vriendelijke groeten, Remco Post SARA - Reken- en Netwerkdiensten http://www.sara.nl High Performance Computing Tel. +31 20 592 3000 Fax. +31 20 668 3167 PGP Key fingerprint = 6367 DFE9 5CBC 0737 7D16 B3F6 048A 02BF DC93 94EC "I really didn't foresee the Internet.
