Thanks for your replies. I am currently also testing samba4 on FreeNAS
9.2.1 based on FreeBSD with ZFS which provides graphical management of
Samba4. I've noticed FreeNAS uses the Directory Service Role and CIFS
shares roles on the same box by default. These roles are not in isolated
like they could be in jails with virtual networking support and so on.
I would like to be able to maybe suggest the separation to the FreeNAS
developers for stability to improve their software but I would need to know
the technical reasons why the separation is important to be able to do so.
I'm curious can anyone elaborate some more on why Directory Services and
File Sharing roles should be spread across two servers and why file sharing
should be run on a member server? Is it because of winbind? Is it known
to cause lockups to have them on the same server?
Another thing I might like to suggest to the FreeNAS developers. I've
noticed they also provision with NTVFS. I've also noticed I can turn on
S3FS in FreeBSD with ZFS after provision and it seems to fix smbstatus.
It's just that provision is still broken with FreeBSD + ZFS as we all
know. From my research it appears S3FS a better option? Is it pretty
stable at this point? Can anyone see any harm in enabling it after the
fact if samba was originally provisioned with NTVFS?
