A LucidLink filespace provides multiple configuration parameters applicable both locally and/or globally across all clients participating in the global namespace.
While in most circumstances the defaults are sufficient, it is important to understand the many configurable options built into our service.
Currently, the only option in the "Filespace settings" panel in the LucidLink application is for an administrator to delete the filespace. More features will be present in future releases.
Managing Filespace Users, Filespace Groups, administering their Permissions, and setting up point-in-time Snapshots are covered in separate knowledge base articles. In this article, we will focus specifically on filespace settings.
Open your LucidLink desktop application and select the relevant filespace from within the relevant workspace. You can then use the drop-down menu and select "Filespace settings".
Advanced Filespace configuration
The lucid3 config command-line interface provides far more detailed administration of your Filespace than what is currently available in "Filespace settings".
Make changes carefully as the performance of your Filespace or network could be affected by incorrectly set parameters.
lucid3 config
Outputs the effective, configured scope and status of each config key.
Usage:
lucid3 config --list [--effective]
lucid3 config --list --local
lucid3 config --list --global
lucid3 config --explain [--KEY1 --KEY2 ...]
lucid3 config --set [--local] --KEY1 VALUE1 [--KEY2 VALUE2 ...] [--password adminPassword]
lucid3 config --set --global --KEY1 VALUE1 [--KEY2 VALUE2 ...] [--password adminPassword]

--effective Currently effective filespace configurations for this client
--local Local configurations scope. Affects only client where setting is applied
--global Global configurations scope. Affects each client that connects to the filespace unless overridden with --local for a particular client
--set Set configuration key(s). Defaults to `local` scope
--delete Delete configuration key(s). Defaults to `local` scope
--password password An admin user's password. Used with --global and --local options
--list Display the configuration settings per scope
--no-trim Do not trim long configuration values
--explain Describe what each configuration key affects within Lucid and list its value constraints. Can be used with --KEY

Each key can be applied across all clients participating in the filespace, by using --global or locally applied only to the current client instance with --local.
Global operations require the root (or admin) password. Certain operations are effective immediately, while others are only applied when the filespace is next activated.
Examples:
Add txt to the file locking extension list (globally):
default: rvt,dwl,dwl2,dwt,dwg,pptx,xlsx,doc,docx
lucid3 config --set --global --FileSystem.LockingExtensions rvt,dwl,dwl2,dwt,dwg,pptx,xlsx,doc,docx,txt
Confirm effective configuration:
lucid3 config --effective
List local settings:
lucid3 config --list --local
List global settings:
lucid3 config --list --global
Increase local parallel download connection count to 32 (default 64):
lucid3 config --set --local --ObjectScheduler.MaxDownloadConns 32
Limit local download rate to 1MB (default unlimited):
lucid3 config --set --local --ObjectScheduler.MaxDownloadRate 1M
Set global download rate to unlimited (default):
lucid3 config --set --global --ObjectScheduler.MaxDownloadRate
Forbid special characters (locally):
lucid3 config --set --FileSystem.ForbidSpecialCharacters 1
