samba panic since 6.12.6

[th3reverend]

syncing photos from ios to unraid via samba.

was working prior to 6.12.6 update, but i'm not 100% sure what version i was running prior. it was probably 6.12.5. i generally keep up with the updates.

some files may transfer, but it always gets interrupted.

i read some other threads looking for solutions, and tried a few reboots. i also performed a shutdown and i scanned the flash drive for errors. no file system errors were found. i also tried with my plex container turned off.

I do have exactly the same issue. Connections aborts when accessing via MacOS, iOS, iPadOS. Running Unraid 6.12.6

 

Is there any fix / workaround?

[th3reverend]

i have not identified a workaround yet.

I also have the same problem, it occurs on all shares and happens when I move or delete a file manually. Some folders are more vulnerable than others, it seems to me..

 

With this error, the combined mount "/mnt/user" is completely unmounted.. (on my system)

 

When it occurs the only thing that helps is a restart as I don't know how I would have to restart Samba correctly and also do a clean remount..
