rAudio 20250809 - Rpi 4 and 5 systems will not automatically remount network storage (NFS) after cold or warm start.

No issues with Rpi 3b

Manually remounting the storage successfully mounts with no further issue.

It would be great to include a check to ensure that a storage drive is currently mounted before allowing the user to update the library database (or your library will be inaccessible even after remounting the storage drive).

I am seeing something similar with 20250822 and a Pi4. I have two cifs folder entries in fstab, both on the same NAS. One mounts OK, and the other has to be mounted manually.

I did some additional testing around this issue and have some details to share.

To summarize, the issues I was having were:
OnBoard WiFi adapter would intermittently enable itself during system start up (power cycle, or software restart events). Note: The On Board Wi-Fi device / Auto start Access Point was disabled, but the On Board Wi-Fi device was still started.
Storage (NAS) would not automatically remount during startup (intermittent on rPi4, persistent on Rpi5). Manual remount worked fine.
Max Link connection speed was 100 Mbps (should connect at 1 GbE).

Long story short, installing an inexpensive UNmanaged 1 GbE switch between my managed L2/L3 network switch and the rPi4 / rPi5 machines, ALL these problems go away. The addition of an unmanaged switch seems to be a common solution to problems encountered during the auto link negotiation process with the rPis’ (depends on rPi model and network hardware combinations). Further, the potential exists for an intermittent network loop being formed during startup if the Onboard Wi-Fi device is automatically started together with the wired LAN connection (depends on your network topology).

Using an unmanaged switch (in my scenario anyway), I can consistently connect at 1 GbE connection speed, the system will successfully remount my database (NAS) after a power cycle and software restart event, and the Onboard WiFi device is never automatically started.
