Can you make some test with hdparm in both disks (to see disk performance)?
I think the problem can be located in the I/O disk part as it happens when copying data (or rsnapshot is running) from two differents disks Another test you can do is copyin data using ionice (with differents options: "Best effort" or "idle") Best regards -- Mi nueva dirección es: - My new email address is: - Mon nouveau email est: [email protected] ---------------------------------------------------------------------------- Usuario Linux Registrado: #257202 http://www.elsotanillo.net ---------------------------------------------------------------------------- 2011/6/14 Aniruddha <[email protected]>: > On Tue, Jun 14, 2011 at 5:00 PM, Glen Batchelor <[email protected]> > wrote: >> >> >> Which kernel are you using?
