| Hello, There was an outage on one of our servers and after the reboot, mounting of the folder fails on that server with an error message: -bash-4.1# mount -t glusterfs srv1:/gv0 /var/www/html/image/ Mount failed. Please check the log file for more details. -bash-4.1# Looking at the log file glustershd.log file, I see the following: Final graph: +------------------------------------------------------------------------------+ 1: volume gv0-client-0 2: type protocol/client 3: option remote-host srv1 4: option remote-subvolume /root/gluster-vol0 5: option transport-type socket 6: option username 300c24e9-ac51-4735-b1ee-7acdd985ccd5 7: option password 989d61f9-8393-4402-8d3f-988d18e832a6 8: end-volume 9: 10: volume gv0-client-1 11: type protocol/client 12: option remote-host srv2 13: option remote-subvolume /root/gluster-vol0 14: option transport-type socket 15: option username 300c24e9-ac51-4735-b1ee-7acdd985ccd5 16: option password 989d61f9-8393-4402-8d3f-988d18e832a6 17: end-volume 18: 19: volume gv0-replicate-0 20: type cluster/replicate 21: option node-uuid c531d907-2f86-4bec-9ae7-8318e28295bc 22: option background-self-heal-count 0 23: option metadata-self-heal on 24: option data-self-heal on 25: option entry-self-heal on 26: option self-heal-daemon on 27: option iam-self-heal-daemon yes 28: subvolumes gv0-client-0 gv0-client-1 29: end-volume 30: 31: volume glustershd 32: type debug/io-stats 33: subvolumes gv0-replicate-0 34: end-volume 35: +------------------------------------------------------------------------------+ [2014-10-05 03:54:30.790905] I [rpc-clnt.c:1729:rpc_clnt_reconfig] 0-gv0-client-0: changing port to 49152 (from 0) [2014-10-05 03:54:30.798689] I [client-handshake.c:1659:select_server_supported_programs] 0-gv0-client-0: Using Program GlusterFS 3.3, Num (1298437), Version (330) [2014-10-05 03:54:30.805120] I [client-handshake.c:1456:client_setvolume_cbk] 0-gv0-client-0: Connected to 127.0.0.1:49152, attached to remote volume '/root/gluster-vol0'.
