Ok, let explain me by a simple example: - 3 nodes with 1TB disk space, --copies 2 - 50% used Now I want to install a new kernel on one node, so I need to reboot, which takes about 3 minute. At reboot, when sheepdog is stopped, both remaining nodes start object recovery. Each node needs to copy about 0.5*0.5*1TB = 250GB of data. Such large amount of data utilizes the network for 100% until the rebooted node comes up again. That is expected behavior? - Dietmar |
