Re: Preparing for replication: dsync-local(testaccount): Panic: file mbox-lock.c

Replication is not supported with mbox format. You can only do unidirectional sync out of mbox.

I am preparing a bit for setting up replication. However when I manually

seems to be ok. The 2nd time I am getting this error[2].

If I add -1 (one way syncing) the error disappears. Does this mean I

will have problems with setting up replication between these two

servers?
