Hello and thanks for replying,
the "mds10" metadata server seems to have a problem because when i tried to
create a directory i received the output
cannot create [/mnt/pvfs2/file279]Warning: non PVFS2 error code
(19):PVFS_sys_lookup: No such device
The /tmp/pvfs2-server.log file of "mds10" is empty with 0 lines.
The pvfs2tab file in the client node is located under /etc/ folder .
I've noticed that the pvfs2tab in all the metadata servers is not located under
/etc/.
In "mds10" i copied the pvfs2tab file of the client node in the "mds10" folder
/etc/.
And i executed the command:(In my testing, only one metadata server "mds10" is
up and only one client is up which is a datanode too)
sudo /usr/bin/pvfs2-ping -m
/mnt/pvfs2/

The PVFS2 filesystem at /mnt/pvfs2/ appears to have
problems.
Well the metadata server "mds10" seems to have problems.Can these problems be
solved?Cause i need this metadata server for my work.
Thanks, in advance

For pvfs2-ping to work it needs access to a pvfs2tab file. You can see in the
error message the various places the utility looks for that file. I would
recommend placing the pvfs2tab file in the same location as you did on your
client node. One other possibility is to place a pvfs2tab file in the current
directory your shell is in when running the pvfs2-ping command.
It looks like, what you are calling "Client node", is also running a
pvfs2-server process. That is okay, I just wanted to make sure that is what you
intended.
It appears that the pvfs2-server process is not running for some reason on the
host mds10. On mds10 look at the file /tmp/pvfs2-server.log. It should provide
a reason why the server failed to start on that host. If you changed the
default LogFile parameter in the configuration file you should look at the file
in that location.

Hello,
i'm actually testing the pvfs2 with one client which is a datanode too and one
metadata server.I restarted the server again and it didn't output that warning
"Warning: msgpair failed to tcp://xxx.xxx:3334, will retry: Connection refused".
In Client node i executed the command:
sudo /usr/sbin/pvfs2-server /etc/pvfs2-fs.conf -a client1[S 12/15 13:35] PVFS2
Server on node client1 version 2.8.1 starting...
In metadata server "mds10" i executed the command
ps auwwx|grep pvfs2user 3119 0.0 0.0 60244 704 pts/0 S+ 14:17
0:00 grep pvfs2
So, a pvfs2-server is not running.and i started the server.
After starting the mds and the client i could create a directory and i could
list all the files.
But when i executed the following command on metadata server "mds10":
sudo /usr/bin/pvfs2-ping -m /mnt/pvfs2/
(1) Parsing tab file...
[E 15:04:38.583196] Error: could not find any pvfs2 tabfile entries.[E
15:04:38.583287] Error: tried the following tabfiles:[E 15:04:38.583300]
(null)[E 15:04:38.583312] /etc/fstab
[E 15:04:38.583322] /etc/pvfs2tab[E 15:04:38.583344] pvfs2tab[E
15:04:38.583354] /etc/mtabWarning: non PVFS2 error code
(1):PVFS_util_parse_pvfstab: Operation not permitted
Failure: could not parse pvfstab.
Because i can execute pvfs2-mkdir and pvfs-ls without any problem,but when i
execute the command "pvfs2-ping" i receive the errors.
Can i fix these warnings?
Thanks, in advance

It looks like the pvfs2-server process is no longer running. Confirm that a
pvfs2-server process is running on each of the servers. If it is not running,
restart it.

Hello,
i started the client in pvfs2 and in one of the metadata servers.
When i execute the command from the client
sudo /usr/bin/pvfs2-ls -l /mnt/pvfs2/
Warning: msgpair failed to tcp://xxx.x:3334, will retry: Connection refused
Warning: msgpair failed to tcp://xxx.xxx.xxx:3334, will retry: Connection

msgpair to server [UNKNOWN] failed: Connection refused
[E 10:57:26.012214] *** Out of retries.Error: could not initialize any file
systems from /etc/pvfs2tab
Where is the problem located?Can this be solved?
Because i was working on pvfs2 and it's urgent for me because i can't work at
all now
Thanks, in advance
