Ray, Yakov just pointed me to this thread <http://apache-ignite-users.70518.x6.nabble.com/Specifying-location-of-persistent-storage-location-tc16636.html> where user had a problem with IP address changing between the cluster restarts. The persistent data directories inside work/db have names built as a concatenation of local IP addresses and ports. Thus, if your node receives a different IP address between the restarts, you will not have your persistent data since the node will initialise from a different persistent data file. You would need to bind your discovery SPI to specific address to work around that. There is an issue opened to properly fix it.
Please also consider that as a potential cause.
