hi, i'm running 3.1.3. i'm finding that certain machines cant overwrite certain files - getting a operation not permitted. the files are owned by the same user. nothing appears on the gluster nfs log. config: g1:/var/log/glusterfs # gluster volume info Volume Name: glustervol1 Type: Distributed-Replicate Status: Started Number of Bricks: 4 x 2 = 8 Transport-type: tcp Bricks: Brick1: g1:/mnt/glus1 Brick2: g2:/mnt/glus1 Brick3: g3:/mnt/glus1 Brick4: g4:/mnt/glus1 Brick5: g1:/mnt/glus2 Brick6: g2:/mnt/glus2 Brick7: g3:/mnt/glus2 Brick8: g4:/mnt/glus2 Options Reconfigured: performance.write-behind-window-size: 1mb performance.cache-size: 1gb performance.stat-prefetch: 1 network.ping-timeout: 20 diagnostics.latency-measurement: off diagnostics.dump-fd-stats: on when mounted with FUSE - files can be overwritten. this is very disruptive - as it's stalling/breaking complex grid jobs. has anyone seen this behaviour at all? ...any ideas??? regards to all, paul ps - this also happened with 3.1.2. i just upgraded hoping that it would be fixed.
