Node restart reseted used disk space info on dashboard

[Alexey]

This is usually related to databases.
So, please check and fix the corrupted ones:

How to fix a "database disk image is malformed" - Storj Docs

or you may re-create a corrupted ones:

If all databases are ok, then you may rescan pieces following these steps:

@Alexey

• Stop and remove the container (or stop the service, if you use a service based setup)
• Rename the used_space_per_prefix.db database to used_space_per_prefix.db.bak
• Move all databases (*.db) to the temp folder
• Start the node, wait until it would re-create all databases
• Stop the node
• Move databases from the temp folder back to the storage location with replace
• Start the node
• Wait until all used-space-filewalkers will finish the scan without issues (no database or filewalker errors)
• Check the dashboard

If you use a hashstore backend you do not need to do anything, it will correct itself after a while.
