I'm trying to move my root directory from sda5 to sda3.
After running grub2-install and grub2-mkconfig,
my machine will not boot.
I performed the changes using a F33 live DVD which also fails to boot.
After plugging in a USB-connected SD card with Centos 7 on it,
the F33 live DVD decided to boot.
It is what I am running now.
The complaint is UUID 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a not found.
While running F33 live DVD I get
blkid | grep 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a
/dev/loop1: LABEL="Anaconda" UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a"
BLOCK_SIZE="4096" TYPE="ext4"
/dev/mapper/live-rw: LABEL="Anaconda"
UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" BLOCK_SIZE="4096" TYPE="ext4"
/dev/mapper/live-base: LABEL="Anaconda"
UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" BLOCK_SIZE="4096" TYPE="ext4"
I backed up sda5 with rsync -auHAXUUx .
I copied from the backup with the same flags.
I edited the new etc/fstab to point at sda3,
actually LABEL=local3slash .
As root:
grupb2-install
grub2-mkconfig -o .../local3slash/boot/grub2/grub/cfg
Reboot failed and sent me to grub rewscue mode, about which I know nothing.
From .../local3slash/boot ,
grep -r -F 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a .

kernelopts="root=UUID=2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a ro "
What is going on and what can I do about it?
