Subject Question regarding the need to run nodetool repair
Date Fri, 16 Nov 2012 00:12:10 GMT
I have a 4 node cluster,  version 1.1.2, replication factor of 4,
read/write consistency of 3, level compaction. Several questions.

 

1)      Should nodetool repair be run regularly to assure it has
completed before gc_grace?  If it is not run, what are the exposures?

2)      If a node goes down, and is brought back up prior to the 1 hour
hinted handoff expiration, should repair be run immediately?

3)      If the hinted handoff has expired, the plan is to remove the
node and start a fresh node in its place.  Does this approach cause
problems?

 

Thanks
