I had a functioning ksmbd in 24.10.0 and that does not work in 24.10.3.
Any pointers on how to debug this? Thanks.
Even Windows makes client side logs when “it does not work”
Is it kdmbd or smb? How did you get from 24.10.0 to 24.10.3?
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Would love to hear your suggestions.
Why You use samba on Linux? Why not NFS ??
How do you mount at Mint?
BTW.

So, You don’t have mounted your USB stick (drive).
Did you install mount block and usb-storage-uas (for usb3.0) ?

Yeah, sure your Mint supports SMB ?
I think, he didn’t mount the usb, so how can he mount smb share??
The share would exist anyway, if the /mnt/sda1 folder's there, I'd just be empty.

So maybe on openWRT first to do:
ls /mnt/sda1 if not exist:
then
mkdir /mnt/sda1
And mount to ksmb
But he did ls
I am using sda1 just as a directory. I could have named it /mnt/let_me_use_atleast_500mb_of_1gb_of_my_mx65
Before decommissioning this, I did have a functional USB on it and it used to work in 24.10.0
For the purpose of debugging, I thought why mount a USB. However, I will mount and post similar results in a moment.
I can share a directory without any external storage mounted. No?
My laptop is able to access other Openwrt devices with KSMBD fine.
The newifi-d2 is acting as a dumb access point and a tagged switch for lan and iot.
Yes. Even I wanted to tell you that's, you should to that.
So the problem is with ksmbd not with USB.
/etc/init.d/ksmbd status
what is showing? It is running? if not try
/etc/init.d/ksmbd enable
/etc/init.d/ksmbd start
/etc/init.d/ksmbd status
Its running:
Even with the usb drive its the same behavior.
I am downgrading to 24.10.1:
And, I kept the same config during downgrade and it worked.
I used this from custom firmware builder:
openwrt-24.10.1-71071df5536b-bcm53xx-generic-meraki_mx65-squashfs.sysupgrade.bin
So, I suspect that it broke during upgrade builds or there are some config changes imposed on ksmbd which are not known to me.
And, now it works even if I dont want to use USB but use abundant 1GB flash of MX65
Try after upgrade to 24.10.3 reconfig your ksmbd.
You can try uninstall ksmbd and replace it with samba just for tests.
You mean try luci-app-samba4?
Yes. Install full version samba. It take more space, but transfer are faster then ksmbd. (In my case on dir-2660).

Did you see:
check the ksmbd version.
In my case I have ksmbd-server 3.5.4-r1installed.
It is 3.5.3-r1 on mine. Thanks for sharing this thread. I beginning to find that this forum is awesome with such large number of topic specific threads. I will search better next time.
