Run this before an update, when a server becomes slow, or when a backup fails because of insufficient space.
How it works
- The command calculates used space from total capacity and remaining free space.
- The fullest volumes are displayed first.
Precautions
- This command does not delete any files.
- A volume above 90% usage usually deserves further investigation.
Rollback
No rollback is required.
