Description of problem: ======================= While the dbench was in-progress from fuse and nfs mount, brought down the bricks from each replica pair in 6*2 setup. Brought the bricks back after sometime. Dbench failed on nfs mount with following error [19027] unlink ./clients/client6/~dmtmp/WORD/~WRL1146.TMP failed (No such file or directory) - expected NT_STATUS_OK ERROR: child 6 failed at line 19027 Child failed with status 1 [root@darrel n]# [19196] unlink ./clients/client8/~dmtmp/PARADOX/__S31.DB failed (No such file or directory) - expected NT_STATUS_OK ERROR: child 8 failed at line 19196 [root@darrel n]# Version-Release number of selected component (if applicable): ============================================================= glusterfs-3.4.0.12rhs.beta3-1.el6.x86_64 glusterfs-fuse-3.4.0.12rhs.beta3-1.el6.x86_64 glusterfs-rdma-3.4.0.12rhs.beta3-1.el6.x86_64 glusterfs-debuginfo-3.4.0.12rhs.beta3-1.el6.x86_64 glusterfs-devel-3.4.0.12rhs.beta3-1.el6.x86_64 Steps Carried: ============== 1. Created and started 6*2 volume from 4 servers ( server1-4) 2. Mount the volume on client (Fuse and NFS) 3. create directories f and n from fuse mount 4. cd to f from fuse mount and cd to n from nfs mount 5. Turn the metadata,data and entry to off using "for i in {'metadata','data','entry'} ; do gluster volume set <volume_name> $i-self-heal off ; done" 6. Start the dbench from both fuse (f) and nfs (n) directories using dbench -s -F -S --stat-check 10 7. While the dbench was in progress, brought down the bricks from server1 using kill -9 and powered down the server3 8. After few seconds (approx 30) brought back the server3 9. After 2 minutes started the volume forcefully (gluster volume starte vol-dr force) 10. Dbench failed on nfs Actual results: =============== On fuse mount is running successfully On NFS mount it failed with error 10 19579 5.05 MB/sec execute 167 sec latency 4854.036 ms 10 19579 5.02 MB/sec execute 168 sec latency 5854.099 ms [19027] unlink ./clients/client6/~dmtmp/WORD/~WRL1146.TMP failed (No such file or directory) - expected NT_STATUS_OK ERROR: child 6 failed at line 19027 Child failed with status 1 [root@darrel n]# [19196] unlink ./clients/client8/~dmtmp/PARADOX/__S31.DB failed (No such file or directory) - expected NT_STATUS_OK ERROR: child 8 failed at line 19196 Expected results: ================= dbench should not fail, it may hung for few seconds as the process was restarted(via start force0 and than should continue.It should not fail.
