[Gluster-users] gluster v3.0.0 log showing errors
Hello, Recently we've put a gluster v3.0.0 file system into use for a group of apache2/tomcat6 servers. Today one of those servers started hanging and we noticed a lot of lines like the following two in the log file: 1) W [fuse-bridge.c:793:fuse_getattr] glusterfs-fuse: 285653: GETATTR 140556365266128 (fuse_loc_fill() failed) 2) E [afr.c:179:afr_read_child] mirror-0: invalid argument: inode I don't think we're doing anything very strange with this setup. I'm at a loss as to why we are seeing this "hanging" behavior and these errors in the logs. All machines are running v3.0.0 from the same source build. We have 3 bricks using jfs for their backend storage setup to replicate to all three. During testing we discovered that we needed to turn off write-behind to make things like CVS and xsl transformations more reliable in our setup. Write speed of course suffers but that is a compromise we've been willing to live with. There are 7 clients using the file system for web files, java classes, and log files. While this was going on there was an rsync of more images and PDF files copying from an old web server onto the new gluster file system using the client that was "hanging" as it's receiving side. If you could shed any light on what might be causing our problems, it would be very helpful. Thanks!
