Please try again after sometime. The problem is although you are running 3.7.1 binaries the cluster op-version is set to 30501, because of glusterd still goes for acquiring cluster lock instead of volume wise lock for every request. Command log history indicates glusterD is getting multiple volume's status requests and because of it fails to acquire cluster lock. Could you bump up your cluster's op-version by the following command and recheck? gluster volume set all cluster.op-version 30701 ~Atin >>> >>> >>> In /var/log/gluster/etc-glusterfs-glusterd.vol.log I found: >>> >>> [2015-06-09 16:12:38.949842] E [glusterd-utils.c:164:glusterd_lock] >>> 0-management: Unable to get lock for uuid: >>> 99a41a2a-2ce5-461c-aec0-510bd5b37bf2, lock held by: >>> 04a7d2bb-bdd9-4e0d-b460-87ad4adbe12c >>> [2015-06-09 16:12:38.949864] E >>> [glusterd-syncop.c:1766:gd_sync_task_begin] >>> 0-management: Unable to acquire lock >>> >>> I check the files: >>> From server 1: >>> # cat /var/lib/glusterd/peers/04a7d2bb-bdd9-4e0d-b460-87ad4adbe12c >>> uuid=04a7d2bb-bdd9-4e0d-b460-87ad4adbe12c >>> state=3 >>> hostname1=192.168.61.101 >>> >>> From server 2: >>> # cat /var/lib/glusterd/peers/99a41a2a-2ce5-461c-aec0-510bd5b37bf2 >>> uuid=99a41a2a-2ce5-461c-aec0-510bd5b37bf2 >>> state=3 >>> hostname1=192.168.61.100 >> Could you attach the complete glusterd log file and cmd-history.log >> file under /var/log/glusterfs directory?
