Hello, there.
I am coming here seeking words of wisdom. I have looked the interweb and
this list but I cannot seem to find useful informations, so I post here.
I apologize if the answer to the question has already been provided and I
could not find it.
I have a problem with a pvfs2 installation that has been set-up by a third
person. The cluster has been shutdown cleanly for a scheduled maintenance
on the power lines, and I cannot bring pvfs2 up again.
Here is the description.
There is a cluster using a fronted and 9 nodes.
As far as I understand, the fronted is a metadata server, and the nodes
are IO servers, as for the /etc/pvfs2-fs.conf file I present here below:

The nodes are apparently working correctly, at boot the /etc/init.d/pvfs2
script worked and the log file (/tmp/pvfs2-server.log) gives me for a
node:
####################
[D 10/08 14:39] PVFS2 Server version 2.6.2 starting.
####################
on the master instead, it gives
####################
[D 10/09 11:09] PVFS2 Server version 2.6.2 starting.
[E 10/09 11:09] Error: trove_initialize: No such file or directory
[E 10/09 11:09]
***********************************************
[E 10/09 11:09] Invalid Storage Space: /pvfs2-storage-space
[E 10/09 11:09] Storage initialization failed. The most common reason
for this is that the storage space has not yet been
created or is located on a partition that has not yet
been mounted. If you'd like to create the storage space,
re-run this program with a -f option.

Now, the storage space on the nodes is full:
####################
[EMAIL PROTECTED] ~]# ls /pvfs2-storage-space/
744468fe collections.db lost+found storage_attributes.db
####################
on the master (frontend) not:
####################
[EMAIL PROTECTED] ~]# ls /pvfs2-storage-space/
744468fe
####################
Anyone can point me in the right direction?
Thanks Again
Raimondo
