So you formatted /dev/emcpowera and then partitioned the device.
You probably have lost your data on emcpowera. If this is a test system,
I guess you don't care. But as a rule, always use a partitioned device
so as to avoid such problems.
mounted.ocfs2 has a bug in as such that it is still shows emcpowera
as a ocfs2 volume. We will address the bug.
If this is a test system and you did not have data on emcpowera,
mkfs.ocfs2 /dev/emcpowera1 and make the appropriate change
in /etc/fstab and continue.
