### Changing replica count of the volumes
|
||
|
|
|
||
|
|
The default replica count can be changed in the setting.
|
||
|
|
|
||
|
|
Also, when a volume is attached, the user can change the replica count for the volume in the UI.
|
||
|
|
|
||
|
|
Longhorn will always try to maintain at least given number of healthy replicas for each volume. If the current healthy
|
||
|
|
replica count is less than specified replica count, Longhorn will start rebuilding new replicas. If the current healthy
|
||
|
|
replica count is more than specified replica count, Longhorn will do nothing. In the later situation, if user delete one
|
||
|
|
or more healthy replicas, or there are healthy replicas failed, as long as the total healthy replica count doesn't dip
|
||
|
|
below the specified replica count, Longhorn won't start rebuilding new replicas.
