Hi Paul,A few questions:What type of volume is this and what client protocol are you using?What version of Gluster are you using?Regards,NithyaOn 28 December 2017 at 20:09, Paul <flypen@xxxxxxxxx> wrote:______________________________Hi, All,If I set cluster.readdir-optimize to on, the performance of "ls" is better, but I find one problem.# ls# lsfiles.1 files.2 file.3I run ls twice. At the first time, ls returns nothing. At the second time, ls returns all file names.If turn off cluster.readdir-optimize, I don't see this problem.Is there a way to solve this problem? If ls doesn't return the correct file names,Thanks,Paul_________________
