Increased root size partition deletion

I have root partition size of 50G.

/dev/sda1 /boot/efi
/dev/sda2 /boot
/dev/sda3 /part
- rhel-root 50G
-rhel-swap 8G
-rhel -home 200G

Here, I am trying to add /dev/sda4 partition space to rhel-root to make it to 150G.

After partition creation:

/dev/sda1 /boot/efi
/dev/sda2 /boot
/dev/sda3 /part
- rhel-root 50G
-rhel-swap 8G
-rhel -home 200G

/dev/sda4 /part 100G

I followed the below steps:
1.Use vgextend command
# vgextend rhel /dev/sda4
2.Grow the LV using lvextend.
# lvextend /dev/rhel/root /dev/sda4
3.To Grow the file system
# xfs_growfs /dev/rhel/root.

Now I want to delete the /dev/sda4 of 100G space which is added to rhel-root.
Using parted command deleted the partition 4 (/dev/sda4).
rm 4

It asked me to reboot the machine. After machine reboots, it runs into Emergency mode. I can’t able to do anything.
Here,

MY QUESTION is that we already have /dev/sda3 with root, swap, & home, why can’t machine boot from the /dev/sda3. Here I am just deleting the extra space what I added from /dev/sda4 (100G) to /dev/sda3 right.

  • I believe you corrupted your LV because you deleted a volume from underneath it ---
    You'll need to boot from a Live CD and repair your LV using several commands in the lvreduce family

    When using xfs file system add the space is ok, but when you try to remove that space its not allowed in xfs file system, that why you got the error and you need to install new os in your system.
