Hello, My main idea is that currently no one can tell you if the data is consistent on all nodes, for example very simple case: 2 replicated nodes, node1 and node2 I reboot node1 and during this time, someone writes a file which will be written on node2. At this time you have out of sync replication. When node1 comes back up in a few minutes, there is no way to know if this node is with consistent data or not. Some people suggest to run ls -lR but you have to agree that this is not applicable if you have huge file system tree with millions of files. So if I dont access the file which was written on node2 but not synced on node1 it will never be replicated and if something goes wrong with node2 I will loose data. My question is, is there any algorithm, like wit RAID arrays, which can tell you if data/brick should be resynced. as far as I understand currently my only option is to use ls -lR which would force resync and I should execute it on regular basis.
