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*
Code: Select all
mdadm --zero-superblock /dev/sd*4
Code: Select all
mdadm -S /dev/md0
5. Execute the following instructions to delete the mdadm.conf file:
Code: Select all
rm /etc/mdadm.conf
