We have recently migrated our CIFS file storage from a BlueArc system that was in use for about 4 years. To a new NetApp system. We have reports from some users that they are getting a message that files are locked by 'another user' when this cannot be true in cases where only one person has access to a directory. Some ways I have been able to re-create the issue is to select several files (say about 10) and open them at the same time. I can make the error happen on my own workstation. I went back to the old BlueArc system, and I cannot make the error happen using the same practice. I also cannot make the error happen if I slowly open one file at a time, stopping and waiting for one file to open completely before opening the next.
Since my workstation is the same, I am now trying to figure out what could possibly be different between the two NAS systems.
