I got from Hetzner a Server with Centos 6.3 + Plesk (2x3TB Software Raid 1), but the disk partition table is in MS-DOS format with no support for more than 2TB partitions.

I want to change the partition table into GPT format to get one big partition (and keep the software raid).

/dev/sdb1               1        1045     8388608+  83  Linux
/dev/sdb2            1045        1110      524288+  fd  Linux raid autodetect
/dev/sdb3            1110      134785  1073741824+  fd  Linux raid autodetect
/dev/sdb4          134785      364802  1847607768    f  W95 Ext'd (LBA)
/dev/sdb5          134785      364802  1847606744   fd  Linux raid autodetect

Disk /dev/md0: 8589 MB, 8589922304 bytes
Disk /dev/md1: 536 MB, 536858624 bytes
Disk /dev/md3: 1891.9 GB, 1891949166592 bytes (contains only /home, its empty)
Disk /dev/md2: 1099.5 GB, 1099511488512 bytes

Can someone help me with a guide? I am not a newbie, but this time I am confused about this.

Contact Hetzner and tell them to set up the server properly this time. – Michael Hampton Mar 12 '13 at 17:20
Didn't...didn't this question get asked a few days ago? – tombull89 Mar 12 '13 at 17:31
Have them set up LARA KVM-over-IP with an OS install disk and install it the way you want.... – allquixotic Mar 12 '13 at 17:41
@tombull89 Not exactly. – Michael Hampton Mar 12 '13 at 18:04
In that case, either find someone at Hetzner who knows what they're talking about, or take your money elsewhere. – Michael Hampton Mar 12 '13 at 18:46

Hetzner has a good tutorial how to partition and install a server with the rescue system and installimage

Nice idea, to bad that installimage is this time not useful it needs that msdos partion to install. – user164200 Mar 12 '13 at 18:42
I complained to Hetzner about installimage's limitation of not supporting GPT a while ago and they said they were working on adding GPT support but it might be a while. Meanwhile you can edit a local copy and make the needed changes (if you're brave); it's just a perl script. – allquixotic Mar 12 '13 at 18:47
