Error description

  • When migratelp is run on 2nd or 3rd mirror pools copies
    of a LV,
    it returns the following error:
    
    
    # migratelp palv1/1/2 hdisk3
    0516-404 allocp: This system cannot fulfill the
    allocation request.
            There are not enough free partitions or not
    enough physical volumes
            to keep strictness and satisfy allocation
    requests.  The command
            should be retried with different allocation
    characteristics.
    0516-990 migratelp: Unable to create new allocation for
            logical volume palv1.
    

Local fix

Problem summary

  • For LVs using mirror pools, migratelp will fail with above
    message if trying to migrate the 2nd or 3rd copy PPs to another
    disk without explicitly specifying which PPnum to migrate to on
    the new disk.
    When PPnum isn't specified, LVM's allocator is used to find
    a free PP on the specified disk.  The allocator has some logic
    for mirror pool LVs that isn't really valid for migratelp,
    and causes it to incorrectly fail to find a free PP to migrate
    to.
    

Problem conclusion

  • Avoid this logic in the allocator for migratelp.
