Doc Type:	Known Issue
Doc Text:	Sometimes in OCP, instead of using the multipath mapper device, such as /dev/mapper/mpatha, to mount the device, individual paths, such as /dev/sdb, is used. This is because OCP is currently not waiting for the mpath checker default timeout of 30 seconds, but waits for only 10 second and then picks the individual path if the mapper device is not ready. Due to this, we are not benefited by all the advantages of high availability and multipathing for block device. To workaround this issue, delete the app pod which will trigger the restart of the pod. The pod then relogins and undergoes a multipath check.
