# SIGHUP behaviour
|
|
|
|
## Logger
|
|
|
|
Logger level can be reloaded with a SIGHUP.
|
|
|
|
## Storage engine
|
|
|
|
Shards can be added, removed or reloaded with SIGHUP.
|
|
Each shard from the configuration is matched with existing shards by
|
|
comparing paths from `shard.blobstor` section. After this we have 3 sets:
|
|
|
|
1. Shards that are missing from the configuration (or have `mode: disabled`) but are currently open.
|
|
These are closed.
|
|
2. Shards that are added. These are opened and initialized.
|
|
3. Shards that remain in the configuration.
|
|
For these shards we apply reload to a `metabase` only. If `resync_metabase` is true, the metabase is also resynchronized.
|
|
|
|
### Metabase

| `path` | If `path` is different, metabase is closed and opened with a new path. All other configuration will also be updated. |
