During the installation of a bare metal headnode using the Bright Installation ISO written to a USB drive, you may find both the GUI and text installation modes fail or get stuck at the Rootfs step. The message from systemd on the server console may look like this:
"A start job is running for Configuring Bright Cluster Manager Installer Rootfs"
One of the potential causes for this issue is the way the ISO file was written to the USB drive. We have found the tool Rufus appears to modify the ISO Hybrid layout of the ISO. This seems to corrupt the RootFS file.
We recommend writing the ISO file to the USB using the Etcher or dd tool. An example of dd command to write an ISO file is as follows:
# dd if=bright9.0-rocky8u4.iso of=/dev/sdb bs=1024 status=progress
To get the USB device filename, the latest logs in /var/log/messages or dmesg output can be checked, the lsblk command may also help in this case.
