CWWK x86 P5 NAS

[Enquiries]

Built this exact system with NVMe 1TB drives. Multiple attempts at setting up RAID5 have worked only to fail during writes of larger files. Tried different FS, different OS's, and controlling for thermal and still no luck. Any help appreciated.

I’m sorry to hear you’re having trouble setting up RAID 5 with your CWWK x86 P5 NAS. It can be frustrating when things don’t work as expected, especially after multiple attempts.

Here are a few troubleshooting steps and suggestions that might help you resolve the issue:

Check Drive Health: Make sure all your NVMe drives are healthy and functioning properly. You can use tools like smartctl to check the SMART status of each drive. If any drives show signs of failure, that could cause issues with RAID.

Update Firmware and Software: Ensure that your BIOS/firmware is up to date for both your motherboard and the drives. Sometimes, compatibility issues can arise with older versions. Additionally, check that your OS and RAID software are the latest versions.

RAID Controller Settings: If you're using a RAID controller, ensure it's properly configured. Double-check any settings related to caching, write policies, and the RAID level to ensure they align with RAID 5 requirements.

Filesystem Considerations: If you're trying different filesystems, consider using EXT4 or XFS, as they tend to work well with RAID configurations. Also, make sure the filesystem is created with the correct parameters for your use case.

Thermal Management: Since you've already been controlling for thermal issues, consider monitoring temperatures during the RAID operations to see if overheating could be contributing to the failures. Good airflow and proper cooling solutions are crucial.

Test with Smaller Files: As a diagnostic step, try writing smaller files to see if the RAID setup holds up under less stress. This can help determine if the issue is specifically related to larger files or if it's more systemic.

Consider Different RAID Levels: If RAID 5 continues to give you trouble, you might want to temporarily switch to RAID 1 or RAID 10 to see if that provides more stability while you troubleshoot.
