we're running into a scenario similar to this with CentOS 6, zero length files after a system crash. http://oss.sgi.com/archives/xfs/2012-02/msg00607.html I'm not exactly sure which kernel version they are running in production (its in China), but I'm trying to find out. its probably a year or so old, our manufacturing operations folks do NOT like installing random updates without very good reasons. meanwhile, I wonder if anyone familiar with it knows if the fix that Dave Chinner discusses in that posting I link above has been backported to a recent EL6 kernel. -- john r pierce 37N 122W somewhere on the middle of the left coast
