so Im upgrading from GFS 6.0 to 6.1 and want to run pvcreate /dev/sdb1 and I get Can't initialize physical volume "/dev/sdb1" of volume group "pool_cca" without -ff which is from the old GFS I had on this disk.. How do I correctly remove this? Im not interested in upgrading anything, just blowing it away and starting over. regards, Jason
