The server FS and FSAPPS was rebooted to resolve some locked file and locked user issues. It appears to have worked. While the servers were down images were also made.
FS did not go down gracefully. To bring it down I had to power it off. There were several users with files open – were they “really” open, or were they in an ambiguous locked state similar to the files we were trying to free up? Because of this I had to run vrepair on all volumes – there were many errors on userdata. After the server was back up, there were not any problems with the files we were trying to “free”.
