+# Safe rollout update
+When update DaemonSet ( DS ) break processes who implements fuse mount. 
+And now new pod not remount net device
+
+For better safe update use ``node.updateStrategy.type: OnDelete`` in this need manual update. Steps:
+ - delete DS pods on node where no exists seaweefs PV
+ - cordon or taint node 
+ - evict or delete pods with seaweedfs PV
+ - delete DS pod on node
+ - uncordon or remove taint on node
+ - repeat all steps on all nodes
