Thank you for the instructions. We have only seen this once and it followed a hardware failure of one of four PVFS servers. So I tend to think the file was being written at the time of the hardware failure though I can not be certain. The issue was noticed after the hardware failure had occurred and not before.

We have been unable to duplicate it in a manner that will allow us to find and fix the problem. If you find a way to reliably create this problem please let us know. Meanwhile, instructions for removing a file affected by this issue can be found here: http://www.orangefs.org/trac/orangefs/wiki/ExplainPVFS2RemoveObject. Hope that helps!

We currently have a user who has 72 files in one directory. All are okay except one file that shows up like this in the directory listing: ?????????? ? ? ? ? ? DataFile218 I assume this is corrupted metadata?? Any attempt to access this file with utilities like pvfs2-stat or pvfs2-validate report "no such file or directory". Is there a way to recover this file or remove it? I am tempted to run pvfs2-fsck but I can not find any documentation on it. This is an active filesystem. Would I need to stop all client access in order to run pvfs2-fsck and how long would it take? This is a 146TB filesystem with 11TB in use. Any advise on fixing this problem would be appreciated. -Roger ----------------------------------------------------------- Roger V.
