Hi again, here is some more information: I now could run "gdisk -l /dev/sda" on the Ubuntu 10.04, which I installed with fai and which is not booting:
---------------------------------------------------------------------- GPT fdisk (gdisk) version 0.5.1 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/sda: 23437369344 sectors, 10.9 TiB Disk identifier (GUID): EF622145-AA15-406D-924E-EF9D566D5CF3 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 23437369310 Total free space is 29 sectors (14.5 KiB) Number Start (sector) End (sector) Size Code Name 1 63 409662 200.0 MiB 0700 primary 2 409663 8798270 4.0 GiB 8200 primary 3 8798271 23437369070 10.9 TiB 0700 primary 4 23437369071 23437369310 120.0 KiB EF02 primary ---------------------------------------------------------------------- There are a /boot-Partition on 1, a swap-Partiton on 2 and a /-partition on 3 with 11TByte. The fourth partition was added by setup-storage because of the "gpt-bios" disclabel. Unlike the partition table generated by the Ubuntu Installer-CD, the free space is only 29 sectors, the bios-partition is at the end and its size is smaller. I used following setup-storage config: ---------------------------------------------------------------------- # <type> <mountpoint> <size> <fs type> <mount options> <misc options> disk_config /dev/sda disklabel:gpt-bios primary /boot 200 ext3 defaults primary swap 4G swap defaults primary / 20G- xfs defaults ---------------------------------------------------------------------- The root-nfs, with which the Ubuntu 10.04 was installed has the backported lenny kernel "2.6.32-bpo.3-amd64". Ubuntu 10.04 uses GRUB2, and the loader gets installed with "grub-install /dev/sda". P.S.: Installing Ubuntu 10.04 with partitions <2TB works like a charm, and we are using it heavily at our company. Thank you for this very useful software!
