But that doesn't seem happy with MBR type disks. You don't need GPT
unless the disk is bigger then 2 Gigs and 4k-sector drives start at
750G, at least in the laptop sizes. gdisk -l says this about a
layout created by the Centos installer:
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present
***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format.
***************************************************************
Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.
Disk /dev/sda: 262144000 sectors, 125.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 4E46CCD4-4010-401E-84A8-020B674DA64B
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 262143966
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)
Number Start (sector) End (sector) Size Code Name
1 2048 1026047 500.0 MiB 8300 Linux filesystem
2 1026048 262143999 124.5 GiB 8E00 Linux LVM
Is something really wrong with it?
