Now that worked fine... until I changed the partition table. Disk /dev/md_d5: 2499.9 GB, 2499990978560 bytes 2 heads, 4 sectors/track, 610349360 cylinders Units = cylinders of 8 * 512 = 4096 bytes Device Boot Start End Blocks Id System /dev/md_d5p1 1 244142 976566 83 Linux /dev/md_d5p2 244143 5126956 19531256 8e Linux LVM /dev/md_d5p3 5126957 488279488 1932610128 8e Linux LVM This is how the layout looked before the changes. Device Boot Start End Blocks Id System /dev/md_d5p1 1 244142 976566 83 Linux /dev/md_d5p2 244143 5126956 19531256 8e Linux LVM /dev/md_d5p3 5126957 73478448 273405968 8e Linux LVM This is how it looks now - the fdisk tools (fdisk/cfdisk) are unable to crate a single partition > 2TB. Of course now LVM complains that the PV is too small: WARNING: Physical Volume /dev/md_d5p3 is too large for underlying device PV Size 260.74 GB / not usable 8192.00 EB I was able to restore a somewhat close partition table now... Close enough for the LVM to work correctly.

The partitioning software, or partitioning all by itself?
