@BiswarajPattan, this looks to be duplicate question of https://communities.vmware.com/t5/VMware-vSAN-Discussions/vSAN-datastore/m-p/2942028#M14691
which you appear to have marked as answered (e.g. fixed), as you appear to still be having the same issues you should unmark that as answered, delete this duplicate question and resume on the original thread.

 

It is very likely your cluster still has a node partitioned - the screenshots you shared fluctuated between vsanDatastore being ~20TB and ~40TB indicating you still have a node isolated (assuming they have ~20TB local storage each).
I already informed on where you should start with checking this:
Cluster > Monitor > vSAN > Skyline Health

 

Note in the other thread folks are telling you to check vmkping betweeen the nodes but the commands provided are not entirely sufficient e.g. they don't account for whether you have an MTU issue here or not (e.g. using '1472 -d' (1500 MTU) or '8972 -d' (9000 MTU)).
