Macos File copy to SMB storage Error EINVAL F_PREALLOCATE

[Jamelle]

When I try to copy from my local attached storage to my SMB mapped storage. I get this error

EINVAL: Invalid argument [fcntl(F_PREALLOCATE)]

What I tried

Resetting my source files and directory with chmod 777
Made sure to strip spaces, apostrophes, question marks, quotes from source filenames
Set the destination directory with chmod 777 from the storage server

What I can do

Using finder, I can copy the folder with all the files into the destination. I can make files from finder in the destination. I'm not sure why FreeFileSync doesn't work and finder does work.

That looks like it's working now. I will report back if there are any other issues.

With version 11.10, I'm still (and always have been) getting a variation on this error simply copying from my local Macbook Air to another iMac on our LAN, namely:

"Cannot write file {file path details...}
EIO: Input/output error [fcntl(F_PREALLOCATE)]"

Up until now, I thought perhaps it was because I'm still running High Sierra (10.13.6) on the Air, but having seen that the above turned out to be an application error, I thought I'd finally say something about my variation of it!

Thanks for letting me know. I'll have FFS ignore EIO in this case because F_PREALLOCATE is only "nice to have".
