* 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
```
### Log level
The log level of etcd can be changed dynamically via the API. You can configure debug logging using the commands below.
