Looks like we have some problems after a "running upgrade" from 3.1.3 to 3.2.0 Most pressing is to fix the current error state on pserver12 after the roll-back, the FUSE mount doesn't work: Error messages in pserver12 opt log: [2011-05-11 09:45:03.1147] E [glusterfsd-mgmt.c:628:mgmt_getspec_cbk] 0-glusterfs: failed to get the 'volume file' from server [2011-05-11 09:45:03.1222] E [glusterfsd-mgmt.c:695:mgmt_getspec_cbk] 0-mgmt: failed to fetch volume file (key:storage0) [2011-05-11 09:45:03.1421] W [glusterfsd.c:700:cleanup_and_exit] (-->/usr/lib/libgfrpc.so.0(rpc_clnt_notify+0xcd) [0x7f98a5032c0d] (-->/usr/lib/libgfrpc.so.0(rpc_clnt_handle_reply+0xa4) [0x7f98a50329c4] (-->/usr/sbin/glusterfs(mgmt_getspec_cbk+0x2fb) [0x4080eb]))) 0-: received signum (0), shutting down [2011-05-11 09:45:03.1452] I [fuse-bridge.c:3688:fini] 0-fuse: Unmounting '/opt/profitbricks/storage'. Vol files are located under /mnt/gluster/brick0/config/vols/storage0/ which is mounted and readable. I can ping both servers with the names given in the FUSE vol file, so they are visible. Any ideas appreciated! Best, Martin
