Hi,

I try to install pvfs2 in two nodes, host1 is metadata server and both of
the two hosts are data servers.

But when I use pvfs2-ping to test it, both host1 and host2 gave the same
error.
The output is below. Could anyone tell me where I'm wrong.

Thank you.

[root at host2 ~]# pvfs2-ping -m /mnt/pvfs2

(2) Initializing system interface...

(3) Initializing each file system found in tab file: /etc/fstab...

(4) Searching for /mnt/pvfs2 in pvfstab...

   PVFS2 servers: tcp://host2:3334
   Storage name: pvfs2-fs
   Local mount point: /mnt/pvfs2

   meta servers:
   tcp://host1:3334

   data servers:
   tcp://host1:3334
   tcp://host2:3334

(5) Verifying that all servers are responding...

        Per-server errors:

        Server: tcp://host2:3334: No route to host

(7) Verifying that root handle is owned by one server...

   Root handle: 1048576

[E 00:21:44.713420] msgpair failed, will retry: No route to host

[E 00:21:56.729725] msgpair failed, will retry: No route to host
[E 00:21:58.740788] msgpair failed, will retry: No route to host
[E 00:21:58.740845] *** msgpairarray_completion_fn: msgpair to server
tcp://host1:3334 failed: No route to host
[E 00:21:58.740866] *** Out of retries.
Failure: check root handle failed
PVFS_mgmt_setparam_all: Detailed per-server errors are available (error
class: 0)

        Exactly one server must own the root handle.
        In this setup, no servers own the root handle.

Per-server errors:
=============================================================

The PVFS2 filesystem at /mnt/pvfs2 appears to have problems.
