Hello, I've been fiddling with GlusterFS 3.3 to try and improve performance. It seems something funny has happened in my hacking. Now I am seeing many file access errors like: rsync: read errors mapping "/global/...": No data available (61) An ls -lR shows the files to be there ... Having similar issues trying to open the files in other programs. This doesn't happen all the time, but it is ~ 50% and sort of randomly. But when it starts to happen, say in an rsync over a whole directory, then it continues for each subsequent file. I also see many errors like 1-global-io-cache: page error in /var/log/gluster.log Any ideas? I've tried stopping and bringing gluster back up and remounting. I've found the physical location of a few files on the servers and successfully read them, also rsync'd them locally to /tmp. I am at my wits end here ... up to now GlusterFS was running without a hitch for ~ 1 year. thanks!! -- Doug Schouten Research Associate TRIUMF
