[Gluster-users] Failed to get names of volumes

[s19n]

Hello,

 Gluster 3.3.0 distributed replicated, ext4 bricks. Since this morning I
am unable to check the status of the filesystem:

----- cut here -----
# gluster volume status all
operation failed
 
Failed to get names of volumes
----- cut here -----

Extract from cli.log:

----- cut here -----
[2012-08-27 11:10:00.341089] W [rpc-transport.c:174:rpc_transport_load]
  0-rpc-transport: missing 'option transport-type'. defaulting to "socket"
[2012-08-27 11:10:00.439743] E
  [cli-rpc-ops.c:5657:gf_cli_status_volume_all] 0-cli: status all failed
[2012-08-27 11:10:00.439791] I [input.c:46:cli_batch] 0-: Exiting with:

----- cut here -----

"gluster peer" reports all nodes connected but it seems to be known as
not really reliable.

Any suggestion will be really appreciated.
Best regards
