Hi Daniel,
However, I've been trying to setup an extra swift proxy to offload
some of the CPU usage I've been experiencing in our tests and I
can't really find a way to do so.
What's the correct way to proceed, with gluster's object-storage?
Anyone else has done it?
To increase the proxy server count, edit the file
"/etc/gluster-object/proxy-server.conf and add the line
workers = <count>
Yes, I did that. However the CPU usage gets very high (100% for all
cores) to have all the Gluster and Swift daemons running on the same
machine. We want to separate the processes in the same manner it is
already possible in Swift.
Following Swift's documentation I get stuck at copying the ring
files (do they exist in gluster's object-storage?). Then I've
thought I could simply setup gluster object-storage in a proxy
machine and somehow redirect the requests from the proxy to the
storage machine, but I'm failing miserably that way as well.
For using gluster object-storage, there is no need to generate the
ring files. Please follow the gluster object-storage documentation to
setup the machines.
I read the documentation and there's no mention about separating the
swift/object-storage servers in such way. I already have a working
setup, I just need to add more proxies.
I could, of course, setup two sets of independent servers and somehow do
a messy data sharding between the two servers, but it's simpler and
cheaper to scale just the proxy servers as needed (this is almost
standard procedure in Swift) since, from our measurements, they are the
bottleneck.
Moreover, I downloaded the latest UFO code from git, where it has some
support for specifying external IP addresses for Accounting and Storage
daemons, but I'm still failing somewhere at making it work. Requests do
now get processed from an external proxy and forwarded to the correct
auth server, but something seems to be failing in the process.
