'ls -l' from glusterfs client gives Input/output error when one node of 2 node RHS is down

Issue

Getting below mentioned error when executed ls -l from GlusterFS client by keeping one of the Red Hat Storage Servers shutdown.

[user@rhs004 glusterfs]$ ls -l
ls: cannot access MegaSAS.log: Input/output error

Obviously something prevents accessing the file MegaSAS.log. The error happened on one of the GlusterFS clients. the file in question was perfectly accessible on the remaining glusterfs server's local XFS file system.
