[Pvfs2-users] Error running pvfs2-server: Error: handle 0 is invalid (out of bounds)

[Phil Carns]

Hello,

I haven't seen that error message in that particular context before.  In 
general, though, it happens on startup when the server finds that it has 
a handle (storage object) in its directory that doesn't match the ranges 
specified in the configuration file.

In this specific case it thinks there is a handle with value 0 in your 
storage space, which shouldn't happen.

Has the server ever started successfully, or is this the first attempt 
to get it running?

You may want to try just deleting the storage space (the 
/usr2/pvfs-storage directory) and redoing the "-f" step, if you haven't 
already.

You could also try running this command:

pvfs2-showcoll -s /usr2/pvfs-storage -c pvfs2-fs

That should list all of the handles in the storage space so that we can 
confirm if there is really bad data in there or if there is something 
wrong with the server's startup.
