Hi, Sorry for late reply. Please close this bug, it's not a bug in glusterfs. The root cause is in guest VM kernel config where the graceful shutdown of VMs by openstack does not work properly. With correction of kernel, the problem is fixed. Thank you very much for your kindly check. br, Yang Congxue
