Storage-Users Service Configuration
Deprecated Metadata Backend
Starting with Infinite Scale version 3.0.0, the default backend for metadata switched to messagepack. If the setting STORAGE_USERS_OCIS_METADATA_BACKEND
has not been defined manually, the backend will be migrated to messagepack
automatically. Although it is still possible to manually configure xattrs
, this setting should not be used anymore as it will be removed in a later version.
Graceful Shutdown
You can define a graceful shutdown period for the storage-users
service.
The graceful shutdown period is only applicable if the storage-users service runs as standalone service. It does not apply if the storage-users service runs as part of the single binary or as single Docker environment. To build an environment where the storage-users service runs as a standalone service, you must start two instances, one without the storage-users service and one only with the the storage-users service. Note that both instances must be able to communicate on the same network.
|
When hard-stopping Infinite Scale, for example with the kill <pid>
command (SIGKILL), it is possible and likely that not all data from the decomposedfs (metadata) has been written to the storage which may result in an inconsistent decomposedfs. When gracefully shutting down Infinite Scale, using a command like SIGTERM, the process will no longer accept any write requests from other services and will try to write the internal open requests which can take an undefined duration based on many factors. To mitigate that situation, the following things have been implemented:
-
With the value of the environment variable
STORAGE_USERS_GRACEFUL_SHUTDOWN_TIMEOUT
, thestorage-users
service will delay its shutdown giving it time to finalize writing necessary data. This delay can be necessary if there is a lot of data to be saved and/or if storage access/thruput is slow. In such a case you would receive an error log entry informing you that not all data could be saved in time. To prevent such occurrences, you must increase the default value. -
If a shutdown error has been logged, the command-line maintenance tool Inspect and Manipulate Node Metadata can help to fix the issue. Please contact support for details.
CLI Commands
Manage Unfinished Uploads
When using Infinite Scale as user storage, a directory named storage/users/uploads
can be found in the Infinite Scale data folder. This is an intermediate directory based on TUS which is an open protocol for resumable uploads. Each upload consists of a blob and a blob.info file. Note that the term blob is just a placeholder.
-
If an upload succeeds, the blob file will be moved to the target and the blob.info file will be deleted.
-
In case of incomplete uploads, the blob and blob.info files will continue to recieve data until either the upload succeeds in time or the upload expires based on the
STORAGE_USERS_UPLOAD_EXPIRATION
variable, see the table below for details. -
In case of expired uploads, the blob and blob.info files will not be removed automatically. Thus a lot of data can pile up over time wasting storage space.
-
In the rare case of a failure, after the upload succeeded but the file was not moved to its target location, which can happen when postprocessing fails, the situation is the same as with expired uploads.
- Example cases for expired uploads
-
-
When a user uploads a big file but the file exceeds the user-quota, the upload can’t be moved to the target after it has finished. The file stays at the upload location until it is manually cleared.
-
If the bandwith is limited and the file to transfer can’t be transferred completely before the upload expiration time is reached, the file expires and can’t be processed.
-
- There are two commands available to manage unfinished uploads
ocis storage-users uploads <command>
COMMANDS:
list Print a list of all incomplete uploads
clean Clean up leftovers from expired uploads
Command Examples
- Command to identify incomplete uploads
-
ocis storage-users uploads list
Incomplete uploads: - 455bd640-cd08-46e8-a5a0-9304908bd40a (file_example_PPT_1MB.ppt, Size: 1028608, Expires: 2022-08-17T12:35:34+02:00)
- Command to clear expired uploads
-
ocis storage-users uploads clean
Cleaned uploads: - 455bd640-cd08-46e8-a5a0-9304908bd40a (Filename: file_example_PPT_1MB.ppt, Size: 1028608, Expires: 2022-08-17T12:35:34+02:00)
Purge Expired Space Trash-Bin Items
This command is about purging old trash-bin items of project
spaces (spaces that have been created manually) and personal
spaces.
ocis storage-users trash-bin <command>
COMMANDS:
purge-expired Purge all expired items from the trashbin
The configuration for the purge-expired
command is done by using the following environment variables.
-
STORAGE_USERS_PURGE_TRASH_BIN_USER_ID
is used to obtain space trash-bin information and takes the system admin user as the default which is theOCIS_ADMIN_USER_ID
but can be set individually. It should be noted, that theOCIS_ADMIN_USER_ID
is only assigned automatically when using the single binary deployment and must be manually assigned in all other deployments. The command only considers spaces to which the assigned user has access and delete permission. -
STORAGE_USERS_PURGE_TRASH_BIN_PERSONAL_DELETE_BEFORE
has a default value of30 days
, which means the command will delete all files older than30 days
. The value is human-readable, valid values are24h
,60m
,60s
etc.0
is equivalent to disable and prevents the deletion ofpersonal space
trash-bin files. -
STORAGE_USERS_PURGE_TRASH_BIN_PROJECT_DELETE_BEFORE
has a default value of30 days
, which means the command will delete all files older than30 days
. The value is human-readable, valid values are24h
,60m
,60s
etc.0
is equivalent to disable and prevents the deletion ofproject space
trash-bin files.
Caching
The storage-users
service caches stat, metadata and uuids of files and folders via the configured store in STORAGE_USERS_STAT_CACHE_STORE
, STORAGE_USERS_FILEMETADATA_CACHE_STORE
and STORAGE_USERS_ID_CACHE_STORE
. Possible stores are:
Store Type | Description |
---|---|
|
Basic in-memory store and the default. |
|
Advanced in-memory store allowing max size. |
|
Stores data in a configured Redis cluster. |
|
Stores data in a configured Redis Sentinel cluster. |
|
Stores data in a configured etcd cluster. |
|
Stores data using the key-value-store feature of NATS JetStream. |
|
Stores nothing. Useful for testing. Not recommended in production environments. |
-
Note that in-memory stores are by nature not reboot-persistent.
-
Though usually not necessary, a database name and a database table can be configured for event stores if the event store supports this. Generally not applicable for stores of type
in-memory
. These settings are blank by default which means that the standard settings of the configured store apply. -
The storage-users service can be scaled if not using
in-memory
stores and the stores are configured identically over all instances. -
When using
redis-sentinel
, the Redis master to use is configured viaSTORAGE_USERS_STAT_CACHE_STORE_NODES
,STORAGE_USERS_FILEMETADATA_CACHE_STORE_NODES
andSTORAGE_USERS_ID_CACHE_STORE_NODES
in the form of<sentinel-host>:<sentinel-port>/<redis-master>
like10.10.0.200:26379/mymaster
.
