Data Overflow Watch |
Number of seconds the system will monitor metadata and journal data when the journal volume is full (100%). When the metadata area or journal data area is full and no more data can be stored, the system regards this as an error and suspends the pairs in the journal. Range is 0-600 seconds. The UR default is 60; the UR-MF default is 20. In a 3DC multi-target configuration in which three UR sites are combined, if the status of the two mirrors in the primary site is Active and the free space in the journal data area or metadata area is less than a certain amount, one of the mirrors in the journal will be suspended by error, regardless of the value in Data Overflow Watch. |
