We use Netapp disk hardware to mount NFS filesystems to our FreeBSD systems. In the past, two different machines would not recognize locks from each other, and would sometimes cause file collisions. From the same machine, two different processes would recognize locks without a problem. In our experience, the Sun servers that we had also did not have any problems. This was after creating specific tests to make this determination. We reported it to the freebsd developers way back when, and have lost track as to the status of the issue. Does anyone on this list know of the developer that was developing the NFS code ??? or know anything about the issue ??? or have an answer ??? ;) I'd like to talk to him/her to see what the status is in the later FreeBSD 4.x series as well as 5.x Thanks, Tim.
