 Not having any NAS myself -- I'm out of my realm... Everything that
follows is hypothetical.

If the NAS is capable of NFS besides CIFS/SMB (based on
https://searchstorage.techtarget.com/definition/Common-Internet-File-System-CIF
S
CIFS itself is considered obsolete... but other sites suggest that one
install cifs-utils rather than smbfs
https://www.thomas-krenn.com/en/wiki/Simple_Samba_Shares_in_Debian ) --
defining the share as NFS /on the NAS/ and changing the mount command(s) on
the RPi to mount as nfs instead of cifs might improve the behavior.
