Having difficulty mounting an CIFS/SMB share correctly on Manjaro Linux

[pythonmegapixel]

I'm in a situation where I need to mount a share on an off-the-shelf consumer NAS device. The only protocol it supports is CIFS (aka SMB1) - which was already outdated 5-10 years before this device was built, so I've no idea why they used that, but I digress.

 

This outdatedness makes it a bit of a pain to mount from both Windows and Linux, but this specific question concerns Manjaro Linux.

 

I added it to fstab as follows. Imagine device is the hostname of the NAS device, and "me" is both the name of the share and my username on the device. 

//device.local/me /media/me/ME_ON_DEVICE cifs username=me,vers=1.0,noauto,rw,users,_netdev 0

 

I should now be able to execute "mount /media/me/ME_ON_DEVICE", enter my password and have access to the share.

Initially this appears to work - I can list the files on the share and read individual files off it. The problem comes when I try to copy multiple files from the share to my Documents folder.

- In Nemo (a graphical file manager), it gets stuck showing a certain percentage copied and the cancel button does nothing when clicked
- In Thunar (another graphical file manager), it gets stuck showing "Collecting Files" and the cancel button doesn't work
- Using `cp` from the command line, it happily copies some files and then just hangs

 

I've tried adding UID and GID properties to the fstab entry and it made no difference. I tried booting from a different kernel version and it didn't solve the issue (though interestingly it did cause it to get stuck at *different* files to on the original one). I also tried connecting by entering "smb://device.local/me" into the address bar of Nemo and Thunar - it asks for my password and then never accepts it even if it is entered correctly.

 

Any ideas what's going on?
