I am trying to migrate samba domain controller (version 3.6, passdb backend = tdbsam) to a new clustered environment with CTDB (same samba version). I have a functional ceph storage and the ctdbd configured according to the documentation. However, all available guides are for the fresh installations and I can't migrate current data into the CTDB. Simply restoring tdb database into the CTDB doesn't work and it ends with the following error: '2015/05/25 22:25:04.849302 [ 5636]: Invalid version of database dump. File is version 7308332182664266836 but expected version was 1' Converting tdb database with ltdbtool doesn't bring any joy too. How to import tdb samba databases into the ctdb? Thanks, Marko
