hey all,
I have four drives installed in a fresh Rockstor setup, Version 3.8.-12 from which only two are available for a pool creation. SMART works.
I see the two failing Drives in the section “Disks” in the UI with an i badge saying “Disk is a mdraid member” which isn’t true. They had been but I deleted the partition table with several methods (parted, fdisk, dd).
Can someone help me to fix this and get the drives running?
Thx in advance,
elmcrest

I deleted the partition tables as described here (note skip is wrong, should be seek, see comments):
