 # 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 seaweedfs 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 
+Updating seaweed-csi-driver DaemonSet (DS) will break processeses who implement fuse mount:
+newly created pods will not remount net device.
+
+For safe update set `node.updateStrategy.type: OnDelete` for manual update. Steps:
+
+  1. delete DS pods on the node where there is no seaweedfs PV
+  2. cordon or taint node
+  3. evict or delete pods with seaweedfs PV
+  4. delete DS pod on node
+  5. uncordon or remove taint on node
+  6. repeat all steps on [all nodes]
