  • 1.  Migrate data among pools

    Posted Mon May 12, 2025 02:33 PM

    Good afternoon.

    I am running out of space in Pool B and need to move a fileset to Pool C.
    Due to the urgency, I have placed pool C in failure group 1. Failure group 2 will be created in a few weeks.
    I am trying to migrate the data from Pool B to Pool C using ILM policies, but I don't see any data being migrated.
    Is it possible to migrate data from Pool B to Pool C in this situation?

    Hi Alejandro,

    it is possible to migrate data from pool C to pool B. It is just a matter what you fill in FROM POOL and TO POOL. Here is the basic syntax to migrate from pool C to pool B:

    RULE 'CtoB' MIGRATE FROM POOL 'POOLC' to POOL 'POOLB' WHERE ....

    If you want to migrate all file from C to B you can omit the WHERE clause.

    Note, you can also add the second FG for PoolC concurrently and rebalance all blocks using mmrestripefs.
