Re: Question on Disk Layout (Stacking supported ?)

thanks for the feedback. I guess this is the way to go then. I found
this setup very usefull. It allows for auto-resizing and providing one
machine image for multiple use cases (which is good for "the clouds").

And you are right that RedHat EL is the main focus (RHEL 5.4), so the
feedback is very valuable.

Do you have some hint regarding this for "best practice" setups ? (RHEl
Docs ?)

While this is more of a "general storage" issue, do you mean tuning the
scheuler / readahead or tuning dm_crypt ?
