I have a MongoDB cluster, which already has two shares: share1 and share2.
When I add a new share3 to the cluster, data chunk can't migrate to share3.
This is from the mongos log:
2015-08-25T11:50:48.145+0800
[Balancer] balancer move failed:
{ cause: { ok: 0.0, errmsg: "migrate already in progress" }, ok: 0.0,
errmsg: "moveChunk failed to engage TO-shard in the data transfer:
migrate already in progress" } from: share1 to: share3
chunk: min: { colkey: "51f7b17f56240isjduf2716b", colid: "111234322333" }
max: { colkey: "51f7b17f56240isjduf2716b", colid: "111234322333" }
this is the output by command:
db.changelog.find({ what: "moveChunk.to"}).sort({_id:-1}).limit(5).pretty()
