1. A method for safe management of a data storage using a volume manager (VM), the method comprising: a computer receiving an I/O request from the VM; the computer determining whether the I/O request requests a data manipulation on the data storage in an address range that overlaps with an address range of a VM signature stored on the data storage; the computer, responsive to determining that the address range of the data manipulation overlaps with the address range of the VM signature, determining whether an identifier of the VM matches an identifier of a second VM associated with the VM signature; and the computer, responsive to determining that the identifier of the VM does not match the identifier of the second VM, failing the I/O request, thereby preventing an unsafe overwriting of the VM signature on the data storage.
