Re: [gpfsug-discuss] Checking for Stale File Handles

Are you able to explain why you want to check for stale file handles?  Are you attempting to detect failures of some sort, and why do the existing mechanisms in GPFS not provide the functionality you require?

Hi folks,

 

We’re currently investigating a way to check for stale file handles on the nodes across our cluster in a way that minimizes impact to the filesystem and performance.

 

Has anyone found a direct way of doing so? We considered a few methods, including simply attempting to ls a GPFS filesystem from each node, but that might have false positives, (detecting slowdowns as stale file handles), and could negatively impact performance with hundreds of nodes doing this simultaneously.

 

Thanks,

 

Alex
