[Samba] Samba CANNOT work with DNS round-robin (?)
This is posed as a question more that a statement, so if you can show that I'm wrong, please feel free to correct / flame me. A couple of years ago, I identified a file corruption issue caused by two people attempting to edit the same file via two different Samba servers. The file was in a shared file space, mounted on both Samba servers via NFS. The problem, I believe, lies in the fact that the oplock being held on Server A is not visible to Server B, and therefore the users were colliding with each other. Once I forced the users to use one or the other server, based on the files they were accessing, the problem vanished. I would like to set up a system of three Samba servers in a DNS round robin configuration, but I am concerned that this problem will resurface, because there is no way to tell which server the user will get, or to force a group of users onto a specific system. Any thoughts on this? Anthony Ciarochi

Clustered CIFS is hard, and much more work than just having a shared NFS backend. You would start by sharing various tdbs, but tdb performance over NFS is well known to stink, and that is only the start of the problems...
