Subject how come some nodes will drop nodes from the ring and not others?
Date Tue, 20 Jul 2010 23:09:59 GMT
dsh is a distributed shell that basically runs the same command on
multiple servers. Notice that cass03 sees all 4 servers, yet the other
3 only sees three servers? Storage-conf.xml is the same among all
nodes i.e.

<Seeds>
      <Seed>10.129.28.14</Seed>
      <Seed>10.129.28.20</Seed>
      <Seed>10.129.28.22</Seed>
      <Seed>10.129.28.23</Seed>
  </Seeds>

cass02 == 10.129.28.20
