Helios 4 raid device not working

Recommended Posts

Armbianmonitor:

After creating a raid 6 array and creating a filesystem on it I decided to switch to a raid 5 instead. So i re-created the array and after that was done mkfs.ext4 fails every time. The error I get is:

Having to wait for the arrays to be created TWICE now has taken my entire weekend!

 

The armbianmonitor didn't work with the following output:

 

root@helios4:/home/user# armbianmonitor -u
System diagnosis information will now be uploaded to no results to fetchPlease post the URL in the forum where you've been asked for.

 

Can anyone help me determine why this error is happening? It'd be much appreciated!

Armbian is a community driven open source project. Do you like to contribute your code?

What is the size of your RAID5 array ?

 

Can you copy here the output of command mdadm -D /dev/md*

 

From the look of it you are trying to format a partition than is more than 16TB. The Helios4 System-On-Chip is a 32bit architecture, therefore the max partition size supported is 16TB. If your RAID array is more than 16TB of usable space, then you will need to create more than just one partition.
