[Samba] Samba on Tru64 UNIX Cluster

[Corny Bondad]

Hi Philipp,

I am just starting to get up to speed on Tru64 after the HP-Compaq
merger, but here's my "take" on your question. The smbds use fcntl to
synchronize access to the TDBs and in a Cluster File System, or CFS, the
fcntl call should work across nodes. Therefore the concurrent access of
the TDB by may processes on 2 or more nodes should be OK. I would worry
about though is the NMBD process. There is supposed to be only 1 of
these and in your scenario there will be 2. There may be some
synchronization issues with NMBD though I don't know how big or small
this problem may be.

Subject: [Samba] Samba on Tru64 UNIX Cluster

Hi list,

I am planning to deploy samba 2.2.6 on a two-node cluster running Tru64
UNIX
5.1A. Each node will be running an instance of samba providing different
services, but I want the locks directory to be shared between them so
that if
one node goes down, the other can take over its services and still have
correct
information about open files etc.

My question:
Can the tdb's handle being written to by more than one samba process, or
am
I likely to encounter corruption?

Regards,

Philipp
