on how to operate Garage in such a setup.
|
||||
|
||||
### `db_engine` (since `v0.8.0`)
|
||||
### Top-level configuration options
|
||||
|
||||
By default, Garage uses the Sled embedded database library
|
||||
to store its metadata on-disk. Since `v0.8.0`, Garage can use alternative storage backends as follows:
|
||||
|
||||
| DB engine | `db_engine` value | Database path |
|
||||
| --------- | ----------------- | ------------- |
|
||||
| [Sled](https://sled.rs) | `"sled"` | `<metadata_dir>/db/` |
|
||||
| [LMDB](https://www.lmdb.tech) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
|
||||
| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
|
||||
|
||||
Performance characteristics of the different DB engines are as follows:
|
||||
|
||||
- Sled: the default database engine, which tends to produce
|
||||
large data files and also has performance issues, especially when the metadata folder
|
||||
is on a traditional HDD and not on SSD.
|
||||
- LMDB: the recommended alternative on 64-bit systems,
|
||||
much more space-efficiant and slightly faster. Note that the data format of LMDB is not portable
|
||||
between architectures, so for instance the Garage database of an x86-64
|
||||
node cannot be moved to an ARM64 node. Also note that, while LMDB can technically be used on 32-bit systems,
|
||||
this will limit your node to very small database sizes due to how LMDB works; it is therefore not recommended.
|
||||
- Sqlite: Garage supports Sqlite as a storage backend for metadata,
|
||||
however it may have issues and is also very slow in its current implementation,
|
||||
so it is not recommended to be used for now.
|
||||
|
||||
It is possible to convert Garage's metadata directory from one format to another with a small utility named `convert_db`,
|
||||
which can be downloaded at the following locations:
|
||||
[for amd64](https://garagehq.deuxfleurs.fr/_releases/convert_db/amd64/convert_db),
|
||||
[for i386](https://garagehq.deuxfleurs.fr/_releases/convert_db/i386/convert_db),
|
||||
[for arm64](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm64/convert_db),
|
||||
[for arm](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm/convert_db).
|
||||
The `convert_db` utility is used as folows:
|
||||
|
||||
```
|
||||
convert-db -a <input db engine> -i <input db path> \
|
||||
-b <output db engine> -o <output db path>
|
||||
```
|
||||
|
||||
Make sure to specify the full database path as presented in the table above,
|
||||
and not just the path to the metadata directory.
|
||||
|
||||
### `metadata_fsync`
|
||||
|
||||
Whether to enable synchronous mode for the database engine or not.
|
||||
This is disabled (`false`) by default.
|
||||
|
||||
This reduces the risk of metadata corruption in case of power failures,
|
||||
at the cost of a significant drop in write performance,
|
||||
as Garage will have to pause to sync data to disk much more often
|
||||
(several times for API calls such as PutObject).
|
||||
|
||||
Using this option reduces the risk of simultaneous metadata corruption on several
|
||||
cluster nodes, which could lead to data loss.
|
||||
|
||||
If multi-site replication is used, this option is most likely not necessary, as
|
||||
it is extremely unlikely that two nodes in different locations will have a
|
||||
power failure at the exact same time.
|
||||
|
||||
(Metadata corruption on a single node is not an issue, the corrupted data file
|
||||
can always be deleted and reconstructed from the other nodes in the cluster.)
|
||||
|
||||
Here is how this option impacts the different database engines:
|
||||
|
||||
| Database | `metadata_fsync = false` (default) | `metadata_fsync = true` |
|
||||
|----------|------------------------------------|-------------------------------|
|
||||
| Sled | default options | *unsupported* |
|
||||
| Sqlite | `PRAGMA synchronous = OFF` | `PRAGMA synchronous = NORMAL` |
|
||||
| LMDB | `MDB_NOMETASYNC` + `MDB_NOSYNC` | `MDB_NOMETASYNC` |
|
||||
|
||||
Note that the Sqlite database is always ran in `WAL` mode (`PRAGMA journal_mode = WAL`).
|
||||
|
||||
### `data_fsync`
|
||||
|
||||
Whether to `fsync` data blocks and their containing directory after they are
|
||||
saved to disk.
|
||||
This is disabled (`false`) by default.
|
||||
|
||||
This might reduce the risk that a data block is lost in rare
|
||||
situations such as simultaneous node losing power,
|
||||
at the cost of a moderate drop in write performance.
|
||||
|
||||
Similarly to `metatada_fsync`, this is likely not necessary
|
||||
if geographical replication is used.
|
||||
|
||||
### `block_size`
|
||||
|
||||
Garage splits stored objects in consecutive chunks of size `block_size`
|
||||
(except the last one which might be smaller). The default size is 1MiB and
|
||||
should work in most cases. We recommend increasing it to e.g. 10MiB if
|
||||
you are using Garage to store large files and have fast network connections
|
||||
between all nodes (e.g. 1gbps).
|
||||
|
||||
If you are interested in tuning this, feel free to do so (and remember to
|
||||
report your findings to us!). When this value is changed for a running Garage
|
||||
installation, only files newly uploaded will be affected. Previously uploaded
|
||||
files will remain available. This however means that chunks from existing files
|
||||
will not be deduplicated with chunks from newly uploaded files, meaning you
|
||||
might use more storage space that is optimally possible.
|
||||
|
||||
### `sled_cache_capacity`
|
||||
|
||||
This parameter can be used to tune the capacity of the cache used by
|
||||
[sled](https://sled.rs), the database Garage uses internally to store metadata.
|
||||
Tune this to fit the RAM you wish to make available to your Garage instance.
|
||||
This value has a conservative default (128MB) so that Garage doesn't use too much
|
||||
RAM by default, but feel free to increase this for higher performance.
|
||||
|
||||
### `sled_flush_every_ms`
|
||||
|
||||
This parameters can be used to tune the flushing interval of sled.
|
||||
Increase this if sled is thrashing your SSD, at the risk of losing more data in case
|
||||
of a power outage (though this should not matter much as data is replicated on other
|
||||
nodes). The default value, 2000ms, should be appropriate for most use cases.
|
||||
|
||||
### `lmdb_map_size`
|
||||
|
||||
This parameters can be used to set the map size used by LMDB,
|
||||
which is the size of the virtual memory region used for mapping the database file.
|
||||
The value of this parameter is the maximum size the metadata database can take.
|
||||
This value is not bound by the physical RAM size of the machine running Garage.
|
||||
If not specified, it defaults to 1GiB on 32-bit machines and 1TiB on 64-bit machines.
|
||||
|
||||
### `replication_mode`
|
||||
#### `replication_mode` {#replication_mode}
|
||||
|
||||
Garage supports the following replication modes:

|
|||
lost as rebalancing is a routine operation for Garage, although we cannot
|
||||

||||
|
||||
### `compression_level`
|
||||
#### `metadata_dir` {#metadata_dir}
|
||||
|
||||
The directory in which Garage will store its metadata. This contains the node identifier,
|
||||
the network configuration and the peer list, the list of buckets and keys as well

#### `data_dir` {#data_dir}
|

The directory in which Garage will store the data blocks of objects.
|

should be counted to determine a node's capacity

Since `v0.9.0`, Garage supports multiple data directories with the following syntax:
|
||||
|
||||
```toml
|
||||
data_dir = [
|
||||
{ path = "/path/to/old_data", read_only = true },
|

{ path = "/path/to/new_hdd1", capacity = "2T" },
|
||||
{ path = "/path/to/new_hdd2", capacity = "4T" },
|
||||
]
|
||||
```
|
||||
|
||||
See [the dedicated documentation page](@/documentation/operations/multi-hdd.md)
|
||||
on how to operate Garage in such a setup.
|
||||
|
||||
#### `db_engine` (since `v0.8.0`) {#db_engine}
|
||||
|
||||
Since `v0.8.0`, Garage can use alternative storage backends as follows:
|
||||
|
||||
| DB engine | `db_engine` value | Database path |
|
||||
| --------- | ----------------- | ------------- |
|
||||
| [LMDB](https://www.lmdb.tech) (default since `v0.9.0`) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
|
||||
| [Sled](https://sled.rs) (default up to `v0.8.0`) | `"sled"` | `<metadata_dir>/db/` |
|
||||
| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
|
||||
|
||||
Sled was the only database engine up to Garage v0.7.0. Performance issues and
|
||||
API limitations of Sled prompted the addition of alternative engines in v0.8.0.
|
||||
Since v0.9.0, LMDB is the default engine instead of Sled, and Sled is
|
||||
deprecated. We plan to remove Sled in Garage v1.0.
|
||||
|
||||
Performance characteristics of the different DB engines are as follows:
|
||||
|
||||
- Sled: tends to produce large data files and also has performance issues,
|
||||
especially when the metadata folder is on a traditional HDD and not on SSD.
|
||||
|
||||
- LMDB: the recommended database engine on 64-bit systems, much more
|
||||
space-efficient and slightly faster. Note that the data format of LMDB is not
|
||||
portable between architectures, so for instance the Garage database of an
|
||||
x86-64 node cannot be moved to an ARM64 node. Also note that, while LMDB can
|
||||
technically be used on 32-bit systems, this will limit your node to very
|
||||
small database sizes due to how LMDB works; it is therefore not recommended.
|
||||
|
||||
- Sqlite: Garage supports Sqlite as an alternative storage backend for
|
||||
metadata, and although it has not been tested as much, it is expected to work
|
||||
satisfactorily. Since Garage v0.9.0, performance issues have largely been
|
||||
fixed by allowing for a no-fsync mode (see `metadata_fsync`). Sqlite does not
|
||||
have the database size limitation of LMDB on 32-bit systems.
|
||||
|
||||
It is possible to convert Garage's metadata directory from one format to another
|
||||
using the `garage convert-db` command, which should be used as follows:
|
||||
|
||||
```
|
||||
garage convert-db -a <input db engine> -i <input db path> \
|
||||
-b <output db engine> -o <output db path>
|
||||
```
|
||||
|
||||
Make sure to specify the full database path as presented in the table above
|
||||
(third colummn), and not just the path to the metadata directory.
|
||||
|
||||
#### `metadata_fsync` {#metadata_fsync}
|
||||
|
||||
Whether to enable synchronous mode for the database engine or not.
|
||||
This is disabled (`false`) by default.
|
||||
|
||||
This reduces the risk of metadata corruption in case of power failures,
|
||||
at the cost of a significant drop in write performance,
|
||||
as Garage will have to pause to sync data to disk much more often
|
||||
(several times for API calls such as PutObject).

|
||||
it is extremely unlikely that two nodes in different locations will have a
|
||||
power failure at the exact same time.
|
||||
|
||||
(Metadata corruption on a single node is not an issue, the corrupted data file
|
||||
can always be deleted and reconstructed from the other nodes in the cluster.)
|
||||
|

|
||||
|
||||
Note that the Sqlite database is always ran in `WAL` mode (`PRAGMA journal_mode = WAL`).
|
||||
|
||||
#### `data_fsync` {#data_fsync}
|
||||
|
||||
Whether to `fsync` data blocks and their containing directory after they are
|
||||
saved to disk.
|
||||
This is disabled (`false`) by default.
|
||||
|
||||
This might reduce the risk that a data block is lost in rare
|
||||
situations such as simultaneous node losing power,

#### `block_size` {#block_size}
|

Garage splits stored objects in consecutive chunks of size `block_size`
|
||||
(except the last one which might be smaller). The default size is 1MiB and
|
||||
should work in most cases. We recommend increasing it to e.g. 10MiB if

## The `[consul_discovery]` section
|
||||
### The `[consul_discovery]` section
|
||||
|
||||
Garage supports discovering other nodes of the cluster using Consul. For this
|
||||
to work correctly, nodes need to know their IP address by which they can be
|
||||
reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
|
||||
|
||||
### `consul_http_addr` and `service_name`
|
||||
#### `consul_http_addr` {#consul_http_addr}

|
||||
|
||||
### `api`
|
||||
#### `api` {#consul_api}
|
||||
|
||||
Two APIs for service registration are supported: `catalog` and `agent`. `catalog`, the default, will register a service using
|
||||
the `/v1/catalog` endpoints, enabling mTLS if `client_cert` and `client_key` are provided. The `agent` API uses the
|
||||
`v1/agent` endpoints instead, where an optional `token` may be provided.
|
||||
|
||||
### `service_name`
|
||||
#### `service_name` {#consul_service_name}
|
||||
|

## The `[kubernetes_discovery]` section
|
||||
### The `[kubernetes_discovery]` section
|
||||
|
||||
Garage supports discovering other nodes of the cluster using kubernetes custom
|
||||
resources. For this to work, a `[kubernetes_discovery]` section must be present
|
||||
with at least the `namespace` and `service_name` parameters.
|
||||
|
||||
### `namespace`
|
||||
#### `namespace` {#kube_namespace}
|
||||
|
||||
`namespace` sets the namespace in which the custom resources are
|
||||
configured.
|
||||
|
||||
### `service_name`
|
||||
#### `service_name` {#kube_service_name}
|
||||
|
||||
`service_name` is added as a label to the advertised resources to
|
