I only have the warning with fdisk that it encounters an "invalid flag 0x000 in partition table 4 which will be corrected with write". So I simply don't use fdisk on that disk and I don't know if this is harmful. But thanks for reminding me.
Well, since fdisk is "Partition table manipulator for Linux", you clearly shouldn't use it on disks which don't have a partition-table. And if you use whole disk for LVM, you don't have any partitions there (and shouldn't have partition-table either), and so fdisk is of no use for such a disk. -- Markus Laire _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
