I don't know for sure if it is related, but the result is the same- in my case it says "Disk ok - 2047.93G (53280%) free on \\otz-freenas\flight". It seems to me the problem is related to the disk being completely full. If I look at df on the machine in question, I get the following:

These two plugins have nothing in common, and afaik check_disk should
work fine with negative numbers.

In the past however we've had bugs in the underlying library that
provides the data to check_disk. would you mind trying with the latest
version (1.4.15) and if you still encounter the bug, with the debug
output (-vvv) added?

The same could be done with check_disk_smb if it fails, although I don't
even know if it will print useful data for debugging...

Thanks
