Re: Install on an entire disk without partitioning

[Jacob Evans <lists@xxxxxxxxxxxxxxx>]

I used this layout for lvm, you'll need a dedicated boot partition.

Hope it helps.

Not sure if this helpful (I have not tested that myself) - wondering if you could specify

bootloader --location=partition 

to make it work ? 

see https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-kickstart-syntax.html

As far as I know, LVM is the only way to use disks without partitioning (and I still use partitions with LVM anyway - old habits die hard!) However I doubt a boot partition will work under LVM. I'm a bit out of touch with modern disk/boot architectures however ...

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
Eduardo Bragatto
