Are you sure using conv=sync is what you want? I normally use conv=fdatasync, I'll look up the difference between the two and see if it affects your test. -b ----- Original Message ----- > From: "Pat Haley" <phaley at mit.edu> > To: "Pranith Kumar Karampuri" <pkarampu at redhat.com> > Cc: "Ravishankar N" <ravishankar at redhat.com>, gluster-users at gluster.org, "Steve Postma" <SPostma at ztechnet.com>, "Ben > Turner" <bturner at redhat.com>...

...internals needs to look at this directly before knowing how to fix it. I apologize about the length of thie message, but hope that the information may be useful if any developers can use it to improve Samba's ability to handle DFS. Thank you for your time, Jacob Morzinski <morzinski@mit.edu> 1) Describing the problem ========================= We have a Windows 2003 server with DFS shares. It works fine when accessed from Windows XP clients. Samba (smbclient) can connect to the root of our MS-DFS server, and can connect to the DFS shares if I explicitly tell it to connect t...

Hi Rowland, I made the change you suggested to auto refresh kerberos. It didn't seem to fix the issue unfortunately, even after a machine restart. Following your line of reasoning that it is a Kerberos issue, I then tried to grab a new kerberos ticket on the server in question which appears to fail though. Perhaps this gives some further insight? pi at fs1:~ $ kinit administrator at

I joined a Windows 10 Pro system to my (still experimental) domain. The windows system actually hosts DC2 as a VM, and another Windows (Server 2008 R2) at another location hosts DC1 also as a VM. The two locations are connected via a VPN, both systems run only when needed. The windows system does not directly use DC2 for DNS but instead talks to a DNS resolver that delegates the samba Domain to
