Created attachment 1620039 [details] Cmvlt python script used as IO Description of problem: When on distributed-dispersed volume, add-brick and rebalance is performed with cmvlt python script (see attachment for the script) running as IO, there is glusterfs crash on the client node. Version-Release number of selected component (if applicable): 6.0.14 How reproducible: 1/1 Steps to Reproduce: 1. Create a 3X(4+2) volume. 2. Mount the volume on a client node using FUSE. 3. On the client node, create multiple directories (in this case 5) and start running the python script simultaneously from all the 5 dirs. 4. Add bricks to the volume to convert it into 4X(4+2) and trigger rebalance. 5. Wait for the rebalance to complete. Actual results: * Rebalance completes successfully, without any failures. * But on client node, there IO errors and also glusterfs crashes generating a core file. Expected results: There should be no IO errors and glusterfs crash on client node. Additional info: * For the IO errors , a bug has been raised (https://bugzilla.redhat.com/show_bug.cgi?id=1744881) * sosreports will be shared
