This is pretty wired issue. for kube16 which used for rs1. following script will currpt the file system and make linux vm die.
the reason is we configure the etcd to mount to sdc which is used for root path of azure vm.
however, i don't know why the issue is not happen before. this may be some bug inside linux, normally even we dup mount it will not cruppt the root system.
