*@Prasanna & @Pranith & @Keithley *Thank you very much for this update, let
me try out this with build frm src and then use with Elasticsearch in
kubernetes environment, i will let you know the update.

My hole intention to use this gluster-block solution is to *avoid
Elasticsearch index health turn RED issue due to CorruptIndex* issue by
using GlusterFS & FUSE, *on this regard if any further pointer or forwards
are there will relay appreciate.*

Regards,
Abhijit
