I've been trying to create a server pool in the Oracle VM Manager. However I am getting the following error:

/dev/mapper/271480530748fbd8c is apparently in use by the system; format forced anyway.
WARNING!!! OCFS2 uses the UUID to uniquely identify a file system.
Having two OCFS2 file systems with the same UUID could, in the least,
cause erratic behavior, and if unlucky, cause file system damage.
Please choose the UUID with care.
Seems like there's already an OCFS2 fs on that LUN. Could it be, that you tried to create a server pool on that LUN before, or that this target has been used to host some other OVM repository? If that is the case, then you need to wipe the LUN, before you can create a new OVM repository or server pool for that matter on it.
But please… double check that this LUN isn't in use anywhere else, since you could loose data, if you'd wipe it!
