Loss of Samba/CIFS mount on client

[kilbey1]

I am running TOS 4.2.09-2101251735-P1.04 on an F2-220.

I find t that after some time, the client on which my NAS folders are mounted (a Macbook) runs into a connection error and loses the mounts.
Running Macbook 16" 2019 with Big Sur 11.2.3 (20D91).

When the mounts are lost, I find I can still ping the NAS.

After connectivity is lost, I log into TOS and may see the Samba file server as disabled. I try to restart with the TOS user interface, but it does not succeed. The UI shows an attempt to connect, but the checkbox refreshes to unchecked.

Checking the service from the Service Status panel shows that Samba is disabled.

I SSHed into the NAS as root and ran a Samba restart command, then Samba start command, and the following is returned:

[root@musicinas ~]# /etc/init.d/samba restart

Checking my space shows Used Space 5.37 TB, and Free Space 3.72 TB.

At this point, the only option is to restart the NAS completely. I usually have to restart the NAS about 2 or 3 times a day.

Hi,
Your system does not have the configuration file, you need to reinstall the system:viewtopic.php?f=75&t=423

Do you mean the Samba files? I see I have it.

Also, rebooting the NAS solves the issue, if it makes a difference. The mounts lose connection after some time.

Reinstalling the system is the fastest solution.

Thanks, got stuck on "Loading..." graphic, but only because it took a long time to check the drive. Reset info, apps, etc. and I'm back in business. Appreciate the help.
