This is an annoying problem that I suspect others have...
First, please excuse the nontechnical way I articulate this. I'm not a disk expert.
We have a bunch of disks all mounted under "/proj". E.g. "/proj/alpha", "/proj/beta", "/proj/gamma". If I do an ls on /proj, I only see alpha. If I do a direct "ls /proj/beta", I see it. If I then do a "ls /proj", I see it now whereas I didn't before. It's like you have to kick it with a direct ls before you can see it under /proj. Inspection of the "/proj" file shows that beta was missing.... until I did an ls on it, then it's in the /proj file.
Why is that and is there anything I can do to flush them all out ? Problem is, I don't know what all the files are under /proj, so I can't kick the ones I don't know about
