Hi, as I tried to tell in the title, I had a problem when I changed the device of a shared folder that was being referenced by a NFS share.
After changing the shared folder device I removed the old drive and after a couple of days I realized that I could not see any files through NFS. I could connect but there were not files.
After a while I found that the old device mount point were still existing under /srv directory. Apparently when I changed the shared folder device, the NFS mount point were not updated on /etc/fstab, so I had to delete and recreate the NFS share to reflect the changes on fstab.
After that I had to manually erase the old unused mount point from /srv that was serving as the empty dir I was seeing through NFS.
Thank you and cheers.
