[Gluster-devel] [Gluster-users] Lot of EIO errors in disperse volume

Xavi,
          As I mentioned before the error could happen for any FOP. Will try to run with TRACE debug level. Is there a possibility that we are checking for this attribute on a directory, because a directory does not seem to be having this attribute set. Also is the function to check size and version called after it is decided that heal should be run or is this check is the one which decides whether a heal should be run.

Thanks and Regards,
Ram
