Description of problem: Accessing the mount point gives I/O errors Version-Release number of selected component (if applicable): Mainline How reproducible: always Steps to Reproduce: 1. created a distribute volume with 1 brick 2. on the mount point ran the following scripts a. for i in {1..100} ; do dd if=/dev/urandom of=$i bs=1024 count=1000; done b. for i in {101..200}; do mkdir $i; cd $i; touch $i;done 3. Now access the mount point Actual results: I/O errors are shown and log shows "detected cyclic loop formation during inode linkage."
