NAS542 RAID5 problem

fuzzyram

Hi,

I have a Nas542. It had a disk problem. So I deleted the Raid structure and then want to reinstall Raid5 again. The process starts but cannot complete. It does not give any error. I updated firmware to last version. It does not work anyway. Any idea for solution? Thanks.

If you really have a disk problem it won't be solved by creating a new raid array. Which of course doesn't mean the system shouldn't give a clear error message.

You can probably see what the problem is by logging in over ssh, and execute

cat /proc/mdstat
cat /proc/partitions
df

The first command gives kernel info about the raid array(s), the second about disks and partitions, and the last about filesystems.

Thanks for help. I'll try this.

If you're unable to complete the RAID 5 setup on your Zyxel NAS542 even after updating the firmware and it doesn't give any error messages, consider trying the following steps:

Check Drive Compatibility: Ensure that the hard drives you're using are compatible with the NAS542 and meet the required specifications for RAID 5.

Disk Health: Check the health of your hard drives. Use diagnostic tools to verify that the drives are essay editor functioning correctly and are free from errors.

Drive Installation Order: If you have multiple hard drives, ensure they are installed in the correct order as per your NAS's documentation for RAID 5 configuration.

Initialization Time: RAID 5 setup can take some time, especially if the drives are large. Be patient and allow sufficient time for the NAS to complete the initialization process.

Factory Reset: Consider performing a factory reset on your NAS542 and then attempt the RAID 5 setup again. This will restore the NAS to its default settings and may resolve any configuration issues.
