Forgot to attached. Here it is..
I’m sorry, I mean the first 384 sector.
I am using RHEL5.6 kernel 2.6.18-238.12.1.el5 and have lvm2-2.02.74-5.el5. Here is my lvm.conf.
Can an application data exist here? Like oracle data..
For instance, if I dd out from a PV with bs=512 and count=384 and I saw oracle data on it, is this ok?
Any idea what is the first 512bytes 384 cylinder of a PV is designed or used for?
Can an ordinary application use it?
