...n a linux box (RHEL 4). Since long dormant (>12 hour) shares from one server in particular always have problems for a few seconds when accessing files, I altered my scripts to mount -o remount. I expected it would freshen the mount. Instead of doing a remount however, it appears to be mounting _over_ the original. Not really what I wanted. Any idea why it's doing this? I wanted to avoid doing an unmount then a mount, as some of these scripts may, on ocasion, be run in parallel. I know at least on local drives remounting while in use (at least for read operations), doesn't appear to...

Cost is a factor here otherwise I would go for an Opteron board instead. JC
