[Pvfs2-users] pvfs2-ping says "appears to have problems"

[Murali Vilayannur]

Hi Tommy,
That is really weird..
Your config files all look ok to me..
Were all the servers pointed to the same config files when they were started?
Servers are assigned meta handle ranges and data handle ranges. i.e
they take owner ship
of handle ranges and requests are sent to those servers from the client.
What the error message says below is that the handle for the root
inode does not seem to be claimed by any server which means that it is
outside of any of the servers assigned ranges which is extremely weird
in this case since all the config files appear to be ok here..
SOmething else is going on or you found an elusive bug with the config
files stuff..
thanks,
Murali
