Subject RE: Reducing the number of vnodes

1.2.4. Really hesitant to upgrade versions due to the inevitable issues it
will cause.


Guess I could upgrade a single node and let that run for a while before
upgrading all nodes.

Which C* version are you running? 

You might want to do an upgrade to the latest version before reducing the
vnode counts, a lot of fixes and improvement went in lately, it might help
you getting your repair faster.

I'm thinking about reducing the number of vnodes per server.


We have 3 DC setup - one with 9 nodes, two with 3 nodes each.


Each node has 256 vnodes. We've found that repair operations are beginning
to take too long.


Is reducing the number of vnodes to 64/32 likely to help our situation?

What options do I have for achieving this in a live cluster?
