yeah. e2fsck command also included and all the above commands
were executed in a loop.

I tried running e2fsck after unmount also , i still see the issue
. Here is the output of e2fsck after
unmount .
e2fsck -f -y /dev/sda1
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information /dev/sda1: 12/262144 files
(0.0% non-contiguous), 18510/1048576 blocks
e2fsck return code was 0. after executing e2fsck, i rebooted the node
and when i mount the Hard disk it is failed with the below error.
[ 87.685184] EXT4-fs (sda1): mounting ext2 file system using the ext4
subsystem [ 87.694393] EXT4-fs error (device sda1): ext4_iget:4337:

Kernel version and steps executed hardware environment everything
is same in both the cases.
