I have tested this with hundreds of files, and it works as expected. However, every few days the script that moves the files will have problems with 1 or 2 files during the move. This is one move problem out of roughly 10,000 files that are being moved and I cannot figure out any reason for the intermittent problem.</div><div><br></div><div>Setup details for my gluster configuration shown below.</div><div><br></div><div><div>[root@gfs01bkp logs]# gluster volume info</div><div> </div><div>Volume Name: gfsbackup</div><div>Type: Distribute</div><div>Volume ID: e78d5123-d9bc-4d88-9c73-61d28abf0b41</div><div>Status: Started</div><div>Number of Bricks: 7</div><div>Transport-type: tcp</div><div>Bricks:</div><div>Brick1: gfsib01bkp.corvidtec.com:/data/brick01bkp/gfsbackup</div><div>Brick2: gfsib01bkp.corvidtec.com:/data/brick02bkp/gfsbackup</div><div>Brick3: gfsib02bkp.corvidtec.com:/data/brick01bkp/gfsbackup</div><div>Brick4: gfsib02bkp.corvidtec.com:/data/brick02bkp/gfsbackup</div><div>Brick5: gfsib02bkp.corvidtec.com:/data/brick03bkp/gfsbackup</div><div>Brick6: gfsib02bkp.corvidtec.com:/data/brick04bkp/gfsbackup</div><div>Brick7: gfsib02bkp.corvidtec.com:/data/brick05bkp/gfsbackup</div><div>Options Reconfigured:</div><div>nfs.disable: off</div><div>server.allow-insecure: on</div><div>storage.owner-gid: 100</div><div>server.manage-gids: on</div><div>cluster.lookup-optimize: on</div><div>server.event-threads: 8</div><div>client.event-threads: 8</div><div>changelog.changelog: off</div><div>storage.build-pgfid: on</div><div>performance.readdir-ahead: on</div><div>diagnostics.brick-log-level: WARNING</div><div>diagnostics.client-log-level: WARNING</div><div>cluster.rebal-throttle: aggressive</div><div>performance.cache-size: 1024MB</div><div>performance.write-behind-window-size: 10MB</div><div><br></div><div><br></div><div>[root@gfs01bkp logs]# rpm -qa | grep gluster</div><div>glusterfs-server-3.7.9-1.el6.x86_64</div><div>glusterfs-debuginfo-3.7.9-1.el6.x86_64</div><div>glusterfs-api-3.7.9-1.el6.x86_64</div><div>glusterfs-resource-agents-3.7.9-1.el6.noarch</div><div>gluster-nagios-common-0.1.1-0.el6.noarch</div><div>glusterfs-libs-3.7.9-1.el6.x86_64</div><div>glusterfs-fuse-3.7.9-1.el6.x86_64</div><div>glusterfs-extra-xlators-3.7.9-1.el6.x86_64</div><div>glusterfs-geo-replication-3.7.9-1.el6.x86_64</div><div>glusterfs-3.7.9-1.el6.x86_64</div><div>glusterfs-cli-3.7.9-1.el6.x86_64</div><div>glusterfs-devel-3.7.9-1.el6.x86_64</div><div>glusterfs-rdma-3.7.9-1.el6.x86_64</div><div>samba-vfs-glusterfs-4.1.11-2.el6.x86_64</div><div>glusterfs-client-xlators-3.7.9-1.el6.x86_64</div><div>glusterfs-api-devel-3.7.9-1.el6.x86_64</div><div>python-gluster-3.7.9-1.el6.noarch</div></div><div><br></div>
