I found something contradictory in Oracle VM. Clustered server pool creation in Oracle VM would format my FC LUN as ocfs2 , and start o2cb & ocfs2 services to build cluster environment. After that, when I wanted to create repository on the serverpool, unexpectedly, it told me that the physical disk I chose which is also my FC LUN, already contains a file system. What a contradictory! So what, delete the file system in serverpool? If so, why created it before?!
OVM> list physicaldisk
Command: list physicaldisk

OVM> create serverpool clusterenable=true virtualip=10.84.21.123 physicaldisk=OVM_HDS name=ovmserverpool
Serverpool creation took quite a long time since my FC LUN was big. When the creation completed, my FC LUN was created as ocfs2 and o2cb & ocfs2 services were started on my ovm servers successfully. But then repository creation indeed throws me a big surprise ...
OVM> create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo
Command: create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo

Error Msg: com.oracle.ovm.mgr.api.exception.RuleException: OVMRU_002026E Cannot use or delete physical disk: OVM_HDS, it already contains a file system: [Pool filesystem for ovmserverpool]

What should I do now? Delete the filesystem using dd command? That would destroy the serverpool, right? I'm really confused. My OVM Manager version is 3.1.1.399 which is the latest.
Any tips are appreciated. Thanks.
