Is it possible to recover from a network partition in an mnesia cluster without restarting any of the nodes involved? If so, how does one go about it?

I'm interested specifically in knowing:

  • How this can be done with the standard OTP mnesia (v4.4.7)
  • What custom code if any one needs to write to make this happen (e.g. subscribe to mnesia running_paritioned_network events, determine a new master, merge records from non-master to master, force load table from the new master, clear running parititioned network event -- example code would be greatly appreciated).
  • Or, that mnesia categorically does not support online recovery and requires that the node(s) that are part of the non-master partition be restarted.

While I appreciate the pointers to general distributed systems theory, in this question I am interested in erlang/OTP mnesia only.
