Seeing Gluster directory in Avamar

I have three servers running Red Hat Enterprise Linux 8. The /home directory is mounted via Gluster (https://gluster.org), so it appears as the following in /etc/fstab:

localhost:/gv0 /home glusterfs defaults,_netdev 0 0

Running df -h, it appears as such:

localhost:/gv0 8.2T 142G 8.0T 2% /home

Therein lies my problem. Avamar out of the box doesn't support NFS links, but that's literally the only way to get it. I've tried "Traverse fixed-disk and remote network mounts" in the Avamar Administrator, but no luck.

About a year and a half ago, I worked with DellEMC support on the phone, and they gave me the special sauce to get this to work. IIRC, it's customized *.cmd files placed in /var/avamar; of course, I forgot to record what it was when I rebuilt the servers to go from RHEL 7 to 8. Does anyone have the solution?

Thanks!
