Make USB drive part of raid

Make USB drive part of raid

Postby mushtaqilyas » Sat Jun 15, 2019 11:13 am

Hi All,

I see that mdadm is being used behind the scenes to manage the raid volumes. Could I add one of my USB 3.0 HDD to the raid volume?
How can I reflect the USB drives in the Storage Manager App. I have been able to create a new volume (volume 3) but not sure how to get the USB 3.0 hdd recognized as a potential raid drive?.

Regards,
Mushtaq

I have managed to grow the array (raid) size to 5 drives using mdadm commands. However cannot get the Asustor UI to show the right size which is now 8TB, the size is displayed correctly using mdadm commands in shell though.

Ok, all I had to do was run the commands:
unmount the raid and
e2fsck -f /dev/md2
followed by
resize2fs /dev/md2
and then mount again to show the right size. However the USB disks still appear as missing.
