Description
a) Setting a member with priority=0
epl1:PRIMARY> var cfg = rs.conf() repl1:PRIMARY> cfg.members[3].priority=0; 0 repl1:PRIMARY> rs.reconfig(cfg); { "ok" : 1, "$clusterTime" : { "clusterTime" : Timestamp(1613583361, 1), "signature" : { "hash" : BinData(0,"m6aGLEXeMQA8z9fQU0hAuDZsLXM="), "keyId" : NumberLong("6930282954501390339") } }, "operationTime" : Timestamp(1613583361, 1) } repl1:PRIMARY> rs.conf() { "_id" : "repl1", "version" : 2, "protocolVersion" : NumberLong(1), "writeConcernMajorityJournalDefault" : true, "members" : [ { "_id" : 0, "host" : "127.0.0.1:40001", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 1, "host" : "127.0.0.1:40002", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 2, "host" : "127.0.0.1:40003", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 3, "host" : "127.0.0.1:40004", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 0, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }
b) Taking the PBM status
Cluster: ======== repl1: - repl1/127.0.0.1:40001: pbm-agent v1.4.1 OK - repl1/127.0.0.1:40002: pbm-agent v1.4.1 OK - repl1/127.0.0.1:40003: pbm-agent v1.4.1 OK
c) setting the priority 1 to the member
repl1:PRIMARY> var cfg = rs.conf() repl1:PRIMARY> cfg.members[3].priority=1; 1 repl1:PRIMARY> rs.reconfig(cfg); { "ok" : 1, "$clusterTime" : { "clusterTime" : Timestamp(1613583775, 1), "signature" : { "hash" : BinData(0,"LM7rjKiKLd6V1WR6rcNF5i27o48="), "keyId" : NumberLong("6930282954501390339") } }, "operationTime" : Timestamp(1613583775, 1) } "members" : [ { "_id" : 0, "host" : "127.0.0.1:40001", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 1, "host" : "127.0.0.1:40002", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 2, "host" : "127.0.0.1:40003", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 3, "host" : "127.0.0.1:40004", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 } ],
d) re-checking the PBM status
Cluster: ======== repl1: - repl1/127.0.0.1:40001: pbm-agent v1.4.1 OK - repl1/127.0.0.1:40002: pbm-agent v1.4.1 OK - repl1/127.0.0.1:40003: pbm-agent v1.4.1 OK - repl1/127.0.0.1:40004: pbm-agent v1.4.1 OK
At this point I couldn't see problems with the backup and I suppose it is an informational intent only. However, I am not sure if a 0 priority member should be considered a "hidden" one by the pbm status.
