Subject Need to maintenance on a cassandra node, are there problems with this process
Date Thu, 18 Aug 2011 23:57:31 GMT

version - 0.7.4
cluster size = 3
RF = 3.
data size on a node ~500G

I want to do some disk maintenance on a cassandra node, so the process that
I came up with is

   - drain this node
   - back up the system data space
   - rebuild the disk partition
   - copy data from another node
   - copy data from the backed up system data
   - restart node
   - run nodetool repair

Is this process sane. Never done a read repair on this cluster before, is
that a problem? Should I run it per CF? Would it help if I did this before
bringing the node down?

Any pointers, things to worry about.
