Moving /boot partition to other disk

isaqellari · 08-31-2022, 11:03 AM

Hello,

I have an Oracle Linux VMware virtual machine which has two virtual disks.
On the first disk it is only /boot partition installed and on the other disk it is /root and the rest of OS files installed. Is there any possibility to move the /boot partition from the first disk to the second disk in order to have a VM with only one virtual disk. I want a single disk VM because Oracle Cloud and Azure Cloud supports only single disk VM migration.

BR,
Ilir

I guess the usual resize operations should work on these virtual disks too. Additionally you can also resize the disk itself easily. So you can copy the boot partition to the other disk. You need to make that partition bootable. Actually I don't know if that will work, but you can clone your current disks and work on a copy, so the original system will remain usable as long as the other one is not working properly.

make new boot partition
copy files to new boot partition from old boot partition
change entry in /etc/fstab for the new boot partition
unmount old boot partition and mount new boot partition
reinstall bootloader to mbr of drive with the root/boot partitions
