Dear Gluster Community, I have this setup: 4-Node Glusterfs v5.5 Cluster, using SAMBA/CTDB v4.8 to access the volumes (each node has a VIP)
I was testing this failover scenario: 1. Start Writing 940 GB with small files (64K-100K)from a Win10 Client to node1 2. During the write process I hardly shutdown node1 (where the client is connect via VIP) by turn off the power My expectation is, that the write process stops and after a while the Win10 Client offers me a Retry, so I can continue the write on different node (which has now the VIP of node1). In past time I did this observation, but now the system shows a strange bahaviour: The Win10 Client do nothing and the Explorer freezes, in the backend CTDB can not perform the failover and throws errors. The glusterd from node2 and node3 logs this messages: > [2019-04-16 14:47:31.828323] W [glusterd-locks.c:795:glusterd_mgmt_v3_unlock] > (-->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x24349) > [0x7f1a62fcb349] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x2d950) > [0x7f1a62fd4950] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0xe0359) > [0x7f1a63087359] ) 0-management: Lock for vol archive1 not held > [2019-04-16 14:47:31.828350] W [MSGID: 106117] > [glusterd-handler.c:6451:__glusterd_peer_rpc_notify] 0-management: Lock not > released for archive1 > [2019-04-16 14:47:31.828369] W [glusterd-locks.c:795:glusterd_mgmt_v3_unlock] > (-->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x24349) > [0x7f1a62fcb349] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x2d950) > [0x7f1a62fd4950] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0xe0359) > [0x7f1a63087359] ) 0-management: Lock for vol archive2 not held > [2019-04-16 14:47:31.828376] W [MSGID: 106117] > [glusterd-handler.c:6451:__glusterd_peer_rpc_notify] 0-management: Lock not > released for archive2 > [2019-04-16 14:47:31.828412] W [glusterd-locks.c:795:glusterd_mgmt_v3_unlock] > (-->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x24349) > [0x7f1a62fcb349] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0x2d950) > [0x7f1a62fd4950] > -->/usr/lib64/glusterfs/5.5/xlator/mgmt/glusterd.so(+0xe0359) > [0x7f1a63087359] ) 0-management: Lock for vol gluster_shared_storage not held > [2019-04-16 14:47:31.828423] W [MSGID: 106117] > [glusterd-handler.c:6451:__glusterd_peer_rpc_notify] 0-management: Lock not > released for gluster_shared_storage > > *In my oponion Samba/CTDB can not perform the failover correctly and continue the write process because glusterfs didn't released the lock.* What do you think? It seems to me like a bug because in past time the failover works correctly. Regards David Spisla
