Hi,
I have created a RAID array and then I have instantly created an XSF fylesystem. I have then discovered I should wait for RAID creation completition.
I have deleted the array, restored each drive to factory setting and created a new one.
After about 36 ours the arrays was ready and I have moved to file system creation section finding the previous XSF filesystem (unmounted)
If I try to mount delete it I get the error I have uploaded as screenshot.
How could I move away from this situation, delete the FS and create a ext4 one ?
