RAID formatting stays at 10% or 60%? Can’t skip email verification during initialization?

Post by TMzethar »

Troubleshooting

Applicable models
All TNAS models

Applicable version
TOS 4.x

Cause analysis
Since the previously created RAID information is still left in the hard disk, the RAID information may not be successfully cleared during the RAID formatting process, so that a new RAID cannot be created or an error occurs.

Solution
Perform RAID reset to clear the RAID information in the hard disk (RAID reset is the same as RAID formatting, it will clear the hard disk data partition information)
1.Log in to SSH terminal
2. Execute the following instructions to find all hard disk partitions:
(Replace "*" with the symbol of the corresponding disk)

Code: Select all

ls /dev/sd*
3. Execute the following command to clear the RAID information of all data partitions:

Code: Select all

mdadm --zero-superblock /dev/sd*4
4. If it prompts that the clearing fails, it may be that /dev/md0 is occupied, please execute the following command to stop the activity of /dev/md0:

Code: Select all

mdadm -S /dev/md0
Perform step 3 again

5. Execute the following instructions to delete the mdadm.conf file:

Code: Select all

rm /etc/mdadm.conf
6. Refresh the web page, set the administrator information and format the RAID again.
