Reads directly from the Gluster brick which is on the local filesystem of the server and writes to Gluster mounted FS for replication to other servers.
Yes, but the performance problems people have reported apparently exist even when using the local-read translator to accelerate them. It's been a while since I benchmarked that, so it might not be the case any more.
I usually run backups directly from the local backing store, bypassing gluster entirely - if I ever need to do a restore, I go in through the proper way to avoid making a mess of any metadata. I guess you could split your reads and writes the same way.
