To repair the missing replicas, you can use `volume.fix.replication` in `weed shell`.
### Replicate without deleting
In certain circumstances—like adding/removing/altering replication settings of volumes or servers—the best strategy is to only repair under-replicated volumes and not delete any while working on volume and server modifications, in this citation use the flag `noDelete`:
`volume.fix.replication -noDelete`
After all replications and modifications are finished, desired replication consensus can then be obtained by running `volume.fix.replication` without the 'noDelete' flag.
## Change replication
In `weed shell`, you can change a volume replication setting via `volume.configure.replication`. After that, the volume will become readonly since the replication setting is not matched. You will also need to run 'volume.fix.replication` to create missing replicas.
