It is recommended that remove-brick be run with cluster.force-migration option disabled to prevent possible data corruption. Doing so will ensure that files that receive writes during migration will not be migrated and will need to be manually copied after the remove-brick commit operation. Please check the value of the option and update accordingly.
Do you want to continue with your current cluster.force-migration settings? (y/n) y
