Does the error cause any breakage in your nginx?

I suspect that the reason for the error is that an "uncommon" filesystem
may have more failure modes than a "common" one; and the best way to avoid
filesystem-related problems is to avoid using a network-based filesystem.

If what you have works well enough for you, then it might be simplest to
leave it as-is, and accept that your filesystem sometimes denies "rename"
permission and other times allows "rename" permission.

To investigate further, you may want to enable the debug log, and perhaps
check the full permissions of the files in question and their containing
directories, and see if there is anything that looks unusual.

"full permissions" may not just be "ls -l", depending on the
implementation or configuration details.

I've not; so this is just as much guess work as the previous one :-)

Good luck with it,
