Description dennis.ordiway 2013-12-10 17:56:52 UTC
Installed sernet samba 4, then settled on 3.6 on RHEL 6.4.  When I do "service smb start", RHEL indicates "OK", but the process fails immediately, not showing up in "ps -aef | grep smb".  A "service smb restart", returns "FAILED" for shutdown and "OK" for the start but still fails to start smb.  It leaves a /var/lock/smbd.pid and a /var/lock/subsys/smb  Deleting those files and restarting smb still fails while indicating "OK".  Increased log level to 10 in smb.conf.  Relevant error from /var/log/samba/log.smbd

Installed samba 3.6 on an identical server (these are nodes in an Oracle RAC cluster) without installing sernet or other versions, and that server does not have these problems.

Samba supports transparent upgrades of data structures but not downgrades. Remove the registry.tdb and you should be fine.
Comment 3 Andreas Schneider 2017-01-03 10:23:21 UTC
Samba doesn't support downgrades of tdb files!
