Re: CentOS 7 Installation - No Local Disks detected
Looks like DMRAID was setup and hence the disks were not showing during installation. Performed the following and the issue is now fixed, DEVICE=/dev/sda # dd if=/dev/zero of=$DEVICE bs=512 seek=$(( $(blockdev --getsz $DEVICE) - 1024 )) count=1024 Did the same for /dev/sdb dmraid -r no raid disks

Re: CentOS 8 - Installation Error

CentOS 8 - Installation Error
I am trying to install CentOS 8 and the installation is failing due to the following error,

The boot mode is set to Dual and there is already Ubuntu installed on the SSD's.
Any ideas what could be wrong here please?
Cheers!

Re: A start job is running for dev-mapper-centos\x2droot.device
UPDATE: Looks like the BIOS defaulted on settings maybe due to a dead motherboard battery? However, changed the BOOT options to RAID and can boot into the OS fine now. Did not have to rebuild the server.
Can mark this topic as solved.

Re: A start job is running for dev-mapper-centos\x2droot.device
I seem to be at lost. I cant get to grub.cfg file as from emergency mode there is no /boot directory. And there is no fstab in /etc. There is just fstab.empty.
cat /proc/mdstat gives personalities:
unused: <none>

Re: A start job is running for dev-mapper-centos\x2droot.device
Thanks for that info Trevor. So is there no way for me to boot into the system currently and to backup data/config files from it. Rebuilding a server is not an issue but I am wearing thin on time tbh.
