you have not defined a root partition (/), which is required for installation or Red Hat Enterprise Linux to continue
Hello - I am trying to set up RedHat 7.1 Server to house a Oracle 12c server. So I am creating this on VSphere 6.0. the problem is that I am encountering is the following error message "you have not defined a root partition (/), which is required for installation or Red Hat Enterprise Linux to continue. You have not created a bootable partition". This is happening when I try to create the mount points during the installation of the Red Hat server. The issue is thought that I have created the / partition and it is visible. Can anyone offer any enlightenment. Thank you

Hi,
could you please describe a bit more how you configured the disks in Anaconda? See this page for details.
Patrick, Also consider using the Red Hat Kickstart Configutor https://access.redhat.com/labs/kickstartconfig/ and then put the kickstart some place where the system can see it when you build it. You can define all your partitions through that utility.
Additionally, if you have an existing like-architecture system, you can take a copy of the /root/anaconda*.cfg file and adjust it to something to suit your needs. Also see this discussion https://access.redhat.com/discussions/653333
edited lastly see this Red Hat documentation on kickstarts (docs.redhatcom aka access.redhat.com/documentation)
Patrick, check out these instructions specifically geared to partitioning installation with Anaconda (the graphical gui you speak of) at this Red Hat link https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-disk-partitioning-setup-x86.html
This may make it easier to, look at this youtube video on custom rhel7 partitioning by Sander Van Vugt, (he posted this video, he is a noted instructor and he apparently provides that video for free as a preview of his overall course).
Hello Patrick,
Are you installing from the CD or literately booting from the CD and running commands from the rescue mode? For the remark the / mountpoint is visible confuses me about what you are doing.
Please explain in more detail what you do and maybe make a screenshot of where you see the error message.
Kind regards,
Jan Gerrit
Patrick, for consistency in future builds, perhaps consider some use of RHEL Linux kickstart. Some options are PXE boot with a PXE server (can be a Red Hat Satellite server configured as such. NOTE: constrain/test your PXE server so it doesn't reload other servers inadvertantly, or cause them to hang upon a reboot looking for a PXE image when they should not do so). You can constrain it to a vlan. We had to add "helpers" to our switches to guide authorized systems to the PXE server on a specific subnet. Another alternative, consider puppet or ansible (you don't have to use ansible-tower, you can use the free version that's in EPEL). Puppet comes as part of Satellite version 6.x and is highly versitle. The Red Hat Satellite server also has the means to imbed your kickstarts within it, offering whatever channels or views (version 5 or 6) and adding configuration control (through activation keys or again, via puppet).
It might be a good idea at minimum, once you've built the system you speak of - to save off the /root/anaconda-ks.cfg file, this link explains why (Red Hat documentation). You could put that file on a web server that's visible to the system you're installing and use kickstart in that way as well. You'll have to uncomment/verify your partitioning in the resultant /root/anaconda-ks.cfg file before using it.
The Red Hat Enterprise Linux installation process automatically writes a Kickstart file that contains the settings for the installed system. This file is always saved as /root/anaconda-ks.cfg. You may use this file to repeat the installation with identical settings, or modify copies to specify settings for other systems.
