In preparation for my OCP examination, I am currently playing around with ASM. For this purpose I am using an AWS instance to install and configure my database. So I added my disks, partitioned them using
fdisk and installed ASMLib to manage them. But when I wanted to issue the
createdisk command, this happened:
[root@ip-10-234-66-103 ~]# oracleasm createdisk DATA0 /dev/xvdc1 Device "/dev/xvdc1" is already labeled for ASM disk ""
