Hi, I have been running a few NFS/Samba servers with DRBD and Heartbeat in production for over a year now and can tell you that MS Office applications will usually work correctly. However other applications such as Quickbooks and Revit will break in the event of a failover if you have the document opened. I am not totally sure why this happens, but believe that it may be a matter of file locking and the locks being lost during the switchover. In the case of Revit, all users have been instructed to check out copies of the file to work on locally in their client machines and then check them in when they are done on the redundant server. This is a feature of Revit. In the case of Quickbooks, there is no work-around so far. If anyone else has a better explanation or can think of a workaround, it will be greatly appreciated. In the case of MS Word, for example if you are working on a file and the server switches over right when you are trying to save, the client computer locks up (MS Word hangs) for about 20 to 40 seconds and when the second server starts samba, then the client finishes the write and that's it.
