Hi How does one go about expanding a volume that consists of a distribute -replicate set of machines in 3.0.6? The setup consists of 4 pairs of machines, with 3 bricks per machine. I need to add an additional 5 pair of machines (15 bricks) to the volume, but I don't understand what's required per se. There are currently 4 client machines mounting the volume using the ip.of.first.backend:/volume syntax in fstab where the first backend server provides the general volume to the clients. Looking at some of the past mailing list chatter, it seems scale-n-defrag.sh is what I need, but it's unclear as to how to go about this without distruption to services on the other clients. If I bring up a new client server, copy the vol file and mount that vol using that volfile temporarily to run the defrag, do I have to make all the existing clients also mount that exact same vol file while this is running? Or can they keep running on their old volfile for the duration of the defrag? The last time I tried modifying the vol file by even 1 byte, on the backend that was serving it up, the clients refused to mount it, so not sure how that's supposed to work in this case? Can someone please shed some light into what the correct process to go about this is? Thanks much. Mohan
