Install on an entire disk without partitioning

[Eduardo Bragatto]

Hello,

First of all, my apologies if this questions has already been answered, but I couldn’t find a clear answer in the documentation or searching the list archives.

My goal is to install CentOS 6 and 7 on an entire disk, with no partitioning scheme (e.g. in /dev/xvda).

My first attempt was to use “part …. onpart=xvda”, like this:

zerombr
clearpart --drives=xvda --all --initlabel
part / --fstype ext3 --fsoptions=noatime --onpart=xvda

The installer actually formats /dev/xvda correctly:

             │ Creating ext3 filesystem on /dev/xvda              │


However, it fails right after that because it tries to read the first item from an empty list:

Entering debugger...
> /usr/lib/anaconda/platform.py(640)bootloaderChoices()
-> ret["mbr"] = (bl.drivelist[0], N_("Master Boot Record (MBR)"))
(Pdb) bl.drivelist
[]
(Pdb) ret
{'boot': ('xvda', 'First sector of boot partition')}


What’s the correct way to avoid partitioning entirely, and have the system installed into a whole device?


Kind regards
