Description
For the sake of an index build's commitQuorum, replica set nodes configured with {buildIndexes:false} are not considered data-bearing.
If a commitQuorum includes a voting replica set node that is configured to not build indexes (i.e. buildIndexes: false), the quorum will be unsatisfiable. Therefore, index builds that use the default commitQuorum of 'votingMembers' will fail if there are any of these voting, non-index-building nodes.
The user will either need to specify a different commitQuorum or have an administrator make any buildIndexes:false nodes non-voting.
Description of Linked Ticket
Given a replica set with config like
{
_id: 'rs',
members: [
{
_id: 0,
host: '…',
priority: 3,
},
{
_id: 1,
host: '…',
priority: 1,
},
{
_id: 2,
host: '…',
priority: 0,
hidden: true,
buildIndexes: false,
},
]
}
Building indexes on replica-set with default commitQuorum (votingMembers) seems to wait for build on member that doesn't build indexes (due to replica-set configuration)
I have to lower commitQuorum to majority, otherwise createIndex command doesn't finish.
votingMembers commitQuorum should mean: all data-bearing index-building voting replica set members.
