Subject RE: Exclude a host from the repair process

Hi Jean,

This option is available in C* version 2.1.x & above, where you can specify hosts in nodetool
 repair command . For more detail please visit the link below :

Hi Jean,

All the nodes are not necessary involved in a repair depending on vnodes being enabled or
not, on your topology, on the racks you are using etc.

This being said, if a node was supposed to be part of a repair process, the repair of all
the subranges including the down node will fail. That's what I have seen happening so far.
@Stone Fang, not sure who is right on this (I might have missed some information about this
topic), but there is a ticket about this topic: https://issues.apache.org/jira/browse/CASSANDRA-10446.
You apparently can specify which nodes to repair, but a down node is not automatically ignored
as far as I can tell.

C*heers,

dont think it is necessary to remove the down node.
the repair will continue comparing with other up node.ignore the down node.

If a node is down in my cluster.

Is it possible to exclude him from the repair process in order to continue with the repair?
If not
Is the repair continue reparing the other replicas even if one is down?
Best regards
