Thanks a very nice approach.
If every nodetool repair uses -pr does that satisfy the requirement to
run a repair before GCGraceSeconds expires? In otherwords, will we get a
correct result using -pr everywhere.
Secondly, what's the need for sleep 120?
Cheers,

You can consider adding -pr. When iterating through all your hosts
like this. -pr means primary range, and will do less duplicated work.

I use cron. On one box I just do:
for n in node1 node2 node3 node4 ; do
nodetool -h $n repair
sleep 120
done
A lot easier then managing a bunch of individual crontabs IMHO
although I suppose I could of done it with puppet, but then you always
have to keep an eye out that your repairs don't overlap over time.

Hi all,
So nodetool repair has to be run regularly on all nodes. Does anybody have
any interesting strategies or tools for doing this or is everybody just
setting up cron to do it?
For example, one could write some Puppet code to splay the cron times around
so that only one should be running at once.
Or, perhaps, a central orchestrator that is given some known quiet time and
works its way through the list, running nodetool repair one at a time (using
RPC?) until it runs out of time.
Cheers,
Edward
