Hey guys, I am facing an issue with samba. When i expose a gluster volume using samba so my windows users can connect to it. My windows users normally use Microsoft Office and some use OpenOffice as they store all Excel/PPT/Word file in samba share. Users who use OpenOffice are able to work properly without any issues. But users who use Microsoft Office are not able to even open the files exposed by samba. When they try to open a file they get downloading file and then it timeouts and gives an error cannot read from source. This is my Gluster Server Config # Filestore Volume to be mounted volume gluster-filestore-data type storage/posix option directory /data/mpath2/filestore-data end-volume volume gluster-filestore-data-lock type features/locks subvolumes gluster-filestore-data end-volume volume gluster-filestore-data-brick type performance/io-threads option thread-count 16 subvolumes gluster-filestore-data-lock end-volume volume gluster-filestore-data-server type protocol/server option transport-type tcp option transport.socket.listen-port 7001 option auth.addr.gluster-filestore-data-brick.allow 10.15.* subvolumes gluster-filestore-data-brick end-volume Gluster Client Config volume gluster-filestore-data-1 type protocol/client option transport-type tcp option remote-host 10.15.6.10 option remote-port 7001 option remote-subvolume gluster-filestore-data-brick end-volume volume gluster-filestore-data-2 type protocol/client option transport-type tcp option remote-host 10.15.6.11 option remote-port 7001 option remote-subvolume gluster-filestore-data-brick end-volume volume replicate type cluster/replicate subvolumes gluster-filestore-data-1 gluster-filestore-data-2 end-volume volume writebehind type performance/write-behind option cache-size 1MB subvolumes replicate end-volume volume cache type performance/io-cache option cache-size 512MB subvolumes writebehind end-volume I tested samba without gluster and it works fine so this is not a samba issue. I did some more testing to find out what happening with samba over gluster. I check the logs of samba and when i access files using MS Office i get oplock errors. I tried disabling oplock and MS Office application was able to open the file but in read-only mode but OpenOffice stopepd working now. If i enable oplocks everything started working other than MS Office. I dont see any kind of crash logs or any other logging in gluster logs. Any help please ???? -- Irshad Ahmed

Hi Irshad, Are you using GlusterFS 3.0.5? If not, give 3.0.5 a try and let us know how it goes. If you run into this problem, try capturing some data which can be useful for debugging - * Use 'option trace on' in the locks translator in the vol file The will print debug info in the log (in normal logging mode). * If users are experiencing hung like behavior, initiate a process state dump - kill -USR1 <pid of glusterfs> This will dump the state of glusterfs in /tmp/glusterdump.<pid> Send us the state dump and the logs if you run into the issues you mentioned.
