EV Index location

Hi,

Please help me to understand about the EV index folder locations.

In my EV 10.0.4 servers we have configured EV index location using a mount point which inside have 8 sub folders, the concern here is out of eight folder only one folder is in use for indexing and rest 7 other folders are empty for last one year.

I understand that the EV will use all these 8 folders randomly but in my case only one folder is in use and all others are empty.

Please let me know

Is this cause any issue?

This is how it works?

Thanks,

Moorthi
