+* Disarm alarm
+
+After verifying that the DB size went down after compaction and defragmenting, the alarm needs to be disarmed for etcd to allow writes again.
+
+Command when no internal address is configured on the host:
+```
+docker exec etcd etcdctl alarm list
+docker exec etcd etcdctl alarm disarm
+docker exec etcd etcdctl alarm list
+```
+
+Command when internal address is configured on the host:
+```
+docker exec etcd sh -c "etcdctl --endpoints=\$ETCDCTL_ENDPOINT alarm list"
+docker exec etcd sh -c "etcdctl --endpoints=\$ETCDCTL_ENDPOINT alarm disarm"
+docker exec etcd sh -c "etcdctl --endpoints=\$ETCDCTL_ENDPOINT alarm list"
+```
+
+Example output:
+```
+docker exec etcd etcdctl alarm list
+memberID:x alarm:NOSPACE
+memberID:x alarm:NOSPACE
+memberID:x alarm:NOSPACE
+docker exec etcd etcdctl alarm disarm
+docker exec etcd etcdctl alarm list
+```
