Hello, we have a CTDB based HA Samba in our Ceph Management Solution. It works like a charm and we connect it to existing active directories as well. It's based on vfs_ceph and you can read more about how to configure it yourself on https://www.samba.org/samba/docs/current/man-html/vfs_ceph.8.html. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@xxxxxxxx Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Fr., 13.
