Im putting together a 16 node cassandra cluster (replication factor 2) and want to setup a schedule for nodetool repair
. gc_grace_seconds is at the default.
Two questions:
- My first impulse is to setup a cron job for each machine and attempt to manually randomize the timing around a one week schedule. Is there a better way?
- Does
nodetool repair
have to be run on every system or every # systems/replication factor systems? (IE for my 16 nodes with replication factor 2 - 8 systems - one of each pair)
