Smartfail Architecture

Hi


I am building a cluster with Isilon X 200 × 3 nodes + X 210 × 3 nodes.


The protection level is 2d: 1n.


At this time Smartfail was executed on X200 × 1 node.

What happens when one node fails while running Smartfail?


Will you lose data?

    If a node fails during a SmartFail, the SmartFail will pause, and a FlexProtect job will start immediately with high priority and a high impact policy to as fast as possible re-protect that data into available free space.

    Make sense? 

    SmartFails are like a predictive fail, so by definition a bit lower priority.

    Hi

    Thank you reply.

    The node is read-only during smart fail.

    When smart fail is stopped, will it become Read/Write?
