To repair the entire cluster it is taking 20 days which is really more than the gc_grace_seconds. But, Im not expecting this kind delay to do the repair. My question, Is there any chance to reduce the repair to 7-8 days?

1Provide more info on how many nodes, what is the size of data on each nodes. Are you using incremental or full repair (depends on C* version)? Provide "nodetool status" o/p – dilsingi Feb 15 '18 at 16:02
