borg check on smbfs crashes with errno 22 invalid argument

[bardok]

Hello,

Sorry for my english i'm french.

I have an error while i check my repository after the first create, i use Vorta gui.
This is my third repository on a NAS DNS-320 with alt-f, and it's the first time i want to use it.
I've got two other repository, one on my pc and one a smb share behind a raspberry with omv, no problem with them while one years.

Thanks for your help.

I suspect that this issue has its cause in smbfs.

The place where it is crashing is just a normal read command, so not sure what could be "invalid" there...

There are some other issues open/closed on this issue tracker with people having smbfs / cifs problems, maybe check if you can find some hints there.

did you find out anything you could add here?
