My block storage files disappear when moving to 2nd server

I made a volume and mounted it on my server. I copied my backup to the drive and it copied over no problem. I think detach the volume and move it over to a new server… I mount it and access the drive.. and there are no files on the drive…

What am I doing wrong? I didn't format the drive again. Also when I mouth the volume back onto the original server the file shows up. The first server is RockyLinux and the 2nd is AlmaLinux (using WHM)…

Any help would be greatly appreciated!

Thanks,

Sean
