1. A method comprising:

  • detecting a predictive failure indication for a predictive failure indicated physical disk of a disk group in an information storage subsystem;

    determining an amount of used storage capacity of a lowest capacity physical disk of the disk group;

    comparing a replacement physical disk storage capacity of a replacement physical disk to the used storage capacity;

    when the replacement physical disk capacity is greater than or equal to the used storage capacity even if the replacement physical disk capacity is less than a lowest storage capacity of the lowest capacity physical disk of the disk group, replacing the predictive failure indicated physical disk with the replacement physical disk; and

    when a higher capacity replacement physical disk having a higher capacity than the lowest storage capacity becomes available, replacing the replacement physical disk with the higher capacity replacement physical disk.
