Hello,
I cant seem to find (searching mailing list and wiki) what DHT is? I
come up with some references to it in the mailing list but no
documentation on what it is or does really.
Also, second question, current state of AFR? Should performance/speed
be up to par yet or is that still being worked on?
I setup a working 4-node AFR (2 server, 2 client), and while trying to
untar linux-source-2.6.26.tar I finally gave up waiting after 10
minutes using gluster/afr where nfs finished in 2m54.843s.
Doing a du -hs every roughly 1 second on the linux-source-2.6.26 it
looks like it is writing at about 200k/second or so, compared to 4-10
megs over nfs.
Can anyone suggest some better options for my configs? Am I doing
something whacky?
