Hi,
It seems like the inherited project quota issue [1] with mv has been
resolved with XFS in RHEL9. However, Lustre is a bit strange.
Given a "src" and "dst"(empty) dir these two ways of calling mv behaves
differently:
mv src dst/ (work: no copy)
mv src dst/src (copy, then delete)
I've attached an strace output for both Lustre and XFS. It seems like mv
is handling the fact that Lustre don't have renameat2 a bit differently.
Before I dig further. Is this behavior known?
Cheers,
Hans Henrik
