Filesystem Size Used Avail Capacity Mounted on t/wrkdir/amd64 52G 53M 52G 0% /export/wrkdir/amd64 t/wrkdir/amd64 52G 53M 52G 0% /export/wrkdir/amd64 slippy$ cp build/make/Makefile . cp: build/make/Makefile: Cross-device link slippy$ And, slippy$ cp y4menc.h foobar cp: y4menc.h: Cross-device link slippy$ But the following works because /tmp is mfs and /var/tmp is ufs. slippy$ cp y4menc.h /tmp slippy$ slippy$ cp y4menc.h /var/tmp slippy$ Copying files from one zpool to a dataset in another zpool also works as does copying files from different datasets on the same zpool. Only copying files from/to the same dataset results in cross device link. -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: https://FreeBSD.org NTP: <cy@nwtime.org> Web: https://nwtime.org e^(i*pi)+1=0
