Please send me some information: version of pvfs2, conf file, server log
files, version of OS that you are using, and version of Berkeley DB you
It appears that the servers are working, i.e., communicating with each
other, based on the ping output. So, it seems to me that the metadata for
your system is somehow hosed. There may or may not be a way to recover;
however, I will research the "Resource temporarily unavailable" message
and let you know "why" you might receive this message.
Also, if you have to create a new filesystem anyway, I recommend that you
setup each server as both metadata and I/O. If you are using OrangeFS
(PVFS 2.8.3), you can put the metadata data space and the data data space
on different drives and still have one server access both. If you are not
using OrangeFS, then you will have to put both metadata and data in the
same directory; however, just by simply spreading out the metadata
functionality to all the servers will enhance performance, regardless of
the location of the metadata.
