I have a disk from another server installed on a new server. However, when I try to make a filesystem on it,
# mkfs -t ext4 /dev/sdd1
mke2fs 1.42.8 (20-Jun-2013)
/dev/sdd1 is apparently in use by the system; will not make a filesystem here!
This is a new disk to the new server. It is not mounted.
I deleted the partition sdd1 and recreated it using
cfdisk. It did not help. The same error message.
What's wrong here? How to fix it?
