Subject: recomended bcache setup
Date: Fri, 21 Dec 2012 20:06:41 -0700 [thread overview]
Message-ID: <201212212006.41906.thomas@fjellstrom.ca> (raw)
I'm setting up a little home NAS here, and I've been thinking about using
bcache to speed up the random access bits on the "big" raid6 array (7x2TB).
How does one get started using bcache (custom patched kernel?), and what is
the recommended setup for use with mdraid? I remember reading ages ago that it
was recommended that each component device was attached directly to the cache,
and then mdraid put on top, but a quick google suggests putting the cache on
top of the raid instead.
Also, is it possible to add a cache to an existing volume yet? I have a
smaller array (7x1TB) that I wouldn't mind adding the cache layer to.
