Hello I'm trying to find a solution to an error, maybe someone can help. I'm using Centos 7, and glusterfs 3.6.3. I've got 2 nodes on the same network and a volume replicated. If both nodes are up, the volume is OK, and I can mount it on NFS on each node. If one node is down, when I reboot the other, the volume can't be mounted. I've got the error on log "failed to get the port number for remote subvolume" : +------------------------------------------------------------------------------+ 1: volume data-sync-client-0 2: type protocol/client 3: option ping-timeout 42 4: option remote-host host1 5: option remote-subvolume /gluster 6: option transport-type socket 7: option username fbd26745-afb8-4729-801e-e1a2db8ff38f 8: option password d077f325-1d03-494d-bfe5-d662ce2d22fe 9: option send-gids true 10: end-volume 11: 12: volume data-sync-client-1 13: type protocol/client 14: option ping-timeout 42 15: option remote-host host2 16: option remote-subvolume /gluster 17: option transport-type socket 18: option username fbd26745-afb8-4729-801e-e1a2db8ff38f 19: option password d077f325-1d03-494d-bfe5-d662ce2d22fe 20: option send-gids true 21: end-volume 22: 23: volume data-sync-replicate-0 24: type cluster/replicate 25: subvolumes data-sync-client-0 data-sync-client-1 26: end-volume 27: 28: volume data-sync-dht 29: type cluster/distribute 30: subvolumes data-sync-replicate-0 31: end-volume 32: 33: volume data-sync-write-behind 34: type performance/write-behind 35: subvolumes data-sync-dht 36: end-volume 37: 38: volume data-sync-read-ahead 39: type performance/read-ahead 40: subvolumes data-sync-write-behind 41: end-volume 42: 43: volume data-sync-io-cache 44: type performance/io-cache 45: subvolumes data-sync-read-ahead 46: end-volume 47: 48: volume data-sync-quick-read 49: type performance/quick-read 50: subvolumes data-sync-io-cache 51: end-volume 52: 53: volume data-sync-open-behind 54: type performance/open-behind 55: subvolumes data-sync-quick-read 56: end-volume 57: 58: volume data-sync-md-cache 59: type performance/md-cache 60: subvolumes data-sync-open-behind 61: end-volume 62: 63: volume data-sync 64: type debug/io-stats 65: option latency-measurement off 66: option count-fop-hits off 67: subvolumes data-sync-md-cache 68: end-volume 69: 70: volume meta-autoload 71: type meta 72: subvolumes data-sync 73: end-volume 74: +------------------------------------------------------------------------------+ [2015-07-08 06:06:08.088983] E [client-handshake.c:1496:client_query_portmap_cbk] 0-data-sync-client-1: failed to get the port number for remote subvolume.

I can't find how to resolve it to each boot correctly. I saw on a bug report it's a protection, the volume will stay offline if another node is not online, to avoid stale data. Any idea to force it be online at boot ?
