Hack With V

I booted my ubuntu and i got the BusyBox v1.30.1 (Ubuntu 1:1.30.1-4ubuntu6.1) built-in shell (ash). I tried exit  command and it thrown an error saying that: The root filesystem on /dev/mapper/ubuntu--vg-root requires a manual fsck. (initramfs) exit --> Got error:  The root filesystem on /dev/mapper/ubuntu--vg-root requires a manual fsck.     So I tried to manual check the partition using fsck as below (initramfs) fsck /dev/mapper/ubuntu--vg-root -y --> It checked and fixed all blocks and inodes in given partition. After that reboot the machine (initramfs) reboot  Now the machine bootsup normal
