Got one another doubt,
This is the total space available in the cluster :
TOTAL : 23490G
Use : 10170G
Avail : 13320G
But ecpool shows max avail as just 3 TB. What am I missing ?

without knowing details of your cluster, this is just assumption
guessing, but...
perhaps one of your hosts have less free space then the others,
replicated can pick 3 of the hosts that have plenty of space, but
erasure perhaps require more hosts, so the host with least space is the
limiting factor.
check
ceph osd df tree
to see how it looks.
