Hub Storage

The Hub Server stores repositories and sessions in a filesystem-based database. The database is located under the path C:\ProgramData\Turbo Server\io (formerly C:\turbo-server\io). Administrators should back up that folder in case of drive failure.

The legacy default folder C:\turbo-server\io is a virtualized folder, which will store files in the Turbo Server installation folder sandbox. In addition, any folder under the installation folder will be virtualized and stored in the sandbox. It is recommended to migrate to a folder outside of any virtualized folders.

The recommended action to migrate the legacy Hub storage is to clear the Hub storage setting field which will migrate the data to the new default folder (C:\ProgramData\Turbo Server\io). Prior to migration, please ensure that the Hub storage has been backed up in case of unexpected failures, and that there is enough room in the destination drive.

Hub Storage Out of Disk Space Recovery Steps

In the event that the disk holding the Hub storage runs out of space, the Hub storage will not be able to write blocks which will result in SVM images failing to pull down to clients. The following steps should be performed to ensure that the block storage is healthy:

1. Stop the Turbo Server service on the Hub server using the Services console or executing net stop turbo.
2. Make a backup of the Hub storage folder (default is C:\ProgramData\Turbo Server\io).
3. Clean up files on the disk or extend the partition to add sufficient free disk space.
   Note: The Optimize Storage function may be executed to remove unreferenced blocks and free up storage. If the block storage is missing blocks due to being out of disk space, the Optimize Storage should be executed after a Repair has completed. Optimize Storage requires free space equal to the current size of the block storage folder to complete successfully.
4. Start the Turbo Server service on the Hub server using the Services console or executing net start turbo.
   Note: Ensure that no images are pushed to the Hub until the remainder of the steps are complete.
5. Open the Storage settings page for the Hub server:
   Turbo Server Admin Portal > Domain > Servers > Hub server name > Storage
6. Click the Repair button under Block Storage: Note: This repair process could take up to several hours depending on the size of the block storage.
