Hello dear GNU devs,

I encounter a problem when trying to use `mv`:

`# mv /path/to/some/logfile /path/to/some/archive/logfile.timestamp`

Now when the archive directory is in an id-mapped mount (the real archive is onwned by my user -> id-mapped to a service-user which should analyze these logs) then I get following error:

`mv: cannot create regular file '/path/to/some/archive/logfile.timestamp': Value too large for defined data type`

The specific logfile I used in this attempt is less than a kb - so the size is definitely not the issue - moving it somewhere else works without problems. Thus I conclude that the id-mapped mount is the enemy here.

It might be that the real bug is with the linux version I am currently running - however as the problem indication is a bit off - I assume it is triggering an unexpected case in `mv` - which could be worth investigating (in the unlikely case that anybody has some free capacities ^^...).


mv (GNU coreutils) 9.11
Linux hostname 7.2.3-arch1-2 #1 SMP PREEMPT_DYNAMIC Thu, 03 Sep 2026 17:55:06 +0000 x86_64 GNU/Linux


Thanks and with best regards,
Lenny
