Re: [Gluster-devel] Crawling and indexing hardware

[Marcus Herou]

I didn't mean to criticize GlusterFS at all, just taking Daniel's word how
GlusterFS works. I'm quite a noob at GlusterFS in particular and large
storage solutions in general.

If it is true that the files will be pushed back and forth by just updating
one byte in them it will be an issue however if that's not the case then I
can carry on with my first intent which is to use GlusterFS for storing and
accessing indexed data.
