## Removing a healthy disk
Befor removing a healthy disk from the cluster set its OSD weight(s) to 0 to
move data away. To do that, add `"reweight":0` to etcd key `/vitastor/config/osd/<OSD_NUMBER>`.
For example:
Before removing a healthy disk from the cluster set its OSD weight(s) to 0 to
move data away. To do that, run `vitastor-cli modify-osd --reweight 0 <НОМЕР_OSD>`.
Then wait until rebalance finishes and remove OSD by running `vitastor-disk purge /dev/vitastor/osdN-data`.
Zero weight can also be put manually into etcd key `/vitastor/config/osd/<НОМЕР_OSD>`, for example:
```
etcdctl --endpoints=http://1.1.1.1:2379/v3 put /vitastor/config/osd/1 '{"reweight":0}'
```
Then wait until rebalance finishes and remove OSD by running `vitastor-disk purge /dev/vitastor/osdN-data`.
## Removing a failed disk
If a disk is already dead, its OSD(s) are likely already stopped.
