Root Partition Critically Low Disk Space (<=1% Free)

What does E3-54 mean?

The root partition of the flash disk has 1% or less free space remaining. This is a critical error indicating imminent disk space exhaustion, which can lead to system instability, crashes, inability to write logs, or update firmware. Urgent action is required to prevent system failure.

• Excessive logging or diagnostic data accumulation filling up the root partition.
• Temporary files or partial project downloads that were not properly cleaned up after updates or aborted operations.
• Incorrectly configured parameters for data retention (e.g., Parameter P8-10 Log File Retention Period set to infinite).
• Installation of large firmware images or additional software components without sufficient remaining space.
• Flash memory degradation leading to reduced usable capacity or bad blocks.

Click steps to track your progress.

1. 1

   1. Connect via programming software and navigate to the 'File System Browser' or 'Diagnostic Logs' section.

2. 2

   2. Delete old diagnostic logs, trace files, or temporary project backups from the root partition.

3. 3

   3. Review and adjust data logging parameters (e.g., Parameter P8-10, P8-11) to limit file size or retention periods.

4. 4

   4. Identify and remove any unnecessary software components or outdated project versions installed on the CPU.

5. 5

   5. If permissible and data is backed up, perform a CPU factory reset to clear the entire file system and reload the project.

6. 6

   6. If the issue persists despite cleanup, consider upgrading the CPU to one with larger internal storage capacity.
