    MESSAGE : ZRC=0x8002013A=-2147352262=SQLB_TBSPACE_TOO_SMALL
              "Cannot reduce tablespace size as requested"
    DATA #1 : <preformatted>
    useablePages is less than the High Water Mark
    or usedPages is greater than the High Water Mark
    useablePages   = 32000
    HighWaterMark  = 6
    usedPages      = 16006
    Table space ID = 3
    
    The HWM is calculated using the wrong SMP page and the resulting
    HWM may be less than useablePages and usedPages. The rollforward
    will fail with:
    
    SQL1271W  Database "<dbname>" is recovered but one or more table
    spaces are
    offline on members or nodes "<nodes>".
    
    The table space will be put in the ROLLFORWARD_PENDING state.
    
    LOCAL FIX:
    None.
