Complete EX2 Ultra Storage Full Problem Again

The WD My Cloud EX2 Ultra is widely used for personal and small business storage needs due to its flexibility, RAID support, and centralized backup features. However, many users encounter a frustrating situation where the EX2 Ultra reports storage as full, even when space should be available. Facing the “storage full” problem again can disrupt workflows, backups, and remote access. Understanding why this happens and how to fix it is essential to keep your NAS running smoothly.

Common Causes of the EX2 Ultra Storage Full Issue

Several factors can lead to repeated “full” messages:

Hidden or Orphaned Files: Sometimes deleted files remain in hidden system folders or recycle bins on network shares, continuing to consume space.

Misconfigured RAID Volumes: RAID 1 or RAID 5 arrays may show less usable space than expected, confusing users about true storage capacity.

Snapshots and Backups: If the EX2 Ultra is used for backup jobs or third-party sync tasks, temporary or duplicate data may accumulate.

Corrupt File System: In some cases, the EXT4 file system becomes corrupted, causing the NAS to misreport space.

Firmware Bugs: Outdated firmware can trigger false reporting of drive usage.

How to Diagnose the Problem

When your EX2 Ultra shows full storage, the first step is to check the dashboard. The storage overview will display capacity and usage by volume. Compare this with the actual data stored in your shared folders.

You can also connect via SSH (if enabled) and use commands like df -h to see detailed disk usage. This may reveal if hidden system folders or logs are eating space.

Fixes for the EX2 Ultra Storage Full Problem

Empty the Recycle Bin: Each shared folder has a recycle bin option. Even if you delete files, they may remain in the bin until cleared.

Check Backups and Sync Tasks: If you run SmartWare, Time Machine, or cloud sync, confirm they are not duplicating files unnecessarily.

Firmware Update: Go to the dashboard and update your device to the latest firmware to eliminate known bugs.

Rebuild the Volume: If misreporting continues, backing up your data and recreating the RAID volume may resolve filesystem corruption.

Log File Cleanup: Sometimes large system logs accumulate. Via SSH, advanced users can safely clear unnecessary logs.

Preventing Storage Full Errors

To avoid repeating the issue:

Schedule regular monitoring of available storage.

Enable email alerts on the EX2 Ultra dashboard so you’re notified before the device runs out of space.

Keep RAID arrays healthy by replacing failing drives promptly.

Avoid filling the NAS to 100% capacity—leave at least 10% free for system processes.

Conclusion

The EX2 Ultra storage full problem often arises from hidden files, backups, or RAID misconfigurations rather than actual lack of space. By monitoring usage, updating firmware, and clearing unnecessary data, you can restore storage capacity and prevent disruptions. Proactive maintenance and regular backups will ensure your EX2 Ultra continues to serve as a reliable storage solution without recurring “full” alerts.
