Which is the preferred filesystem for Nexus in Linux

We have a Nexus 3 Server running on CentOS-7 VM, everything related to Nexus is in sepearte directory mounted on a Virtual Hard disk, the file system for this storage is ext4, so my question is
Is it good to have this file system or should I convert it to xfs? considering the long run.

Ext4 is fine, it gives good performance, and is in widespread use with Nexus Repo. We’ve never seen a problem with it.
