I just opened a bug on this, #2459. I can reproduce it effectively at will now. This is over a channel bond into a Nortel switch (not sure which model) Basic volume: gluster volume info fusion Volume Name: fusion Type: Distribute Status: Started Number of Bricks: 6 Transport-type: tcp Bricks: Brick1: dv4-1:/data/brick-md1/fusion Brick2: dv4-2:/data/brick-md1/fusion Brick3: dv4-3:/data/brick-md1/fusion Brick4: dv4-1:/data/brick-md2/fusion Brick5: dv4-2:/data/brick-md2/fusion Brick6: dv4-3:/data/brick-md2/fusion Options Reconfigured: performance.cache-refresh-timeout: 0 performance.stat-prefetch: 0 auth.allow: * NFS mounts use noac, so there should be no attribute caching. doing an cat /x/y/z/* produces cat: /x/y/z/a: Input/output error cat: /x/y/z/b: Input/output error cat: /x/y/z/c: Input/output error cat: /x/y/z/d: Input/output error I have a partial work around, but this one is troublesome. Anyone experience anything like this? If so, please contact me offline so we can compare notes.
