Did you see a problem with > that? Sorry, I made a mistake. I tested 228 in RHEL8 before. It's failed. Maybe it needs some patches. Now I re-test 228 in 5.8.0-rc7+. It's passed for both servers. And 213 is also passed if "strict allocate = yes" is set. And now I met another issue for windows file server. client is 5.8.0-rc7+. # truncate -s 320k windows/file # fallocate -o 2k -l 256k windows/file fallocate: fallocate failed: Operation not supported # fallocate -o 320k -l 256k windows/file # Seems the offset for fallocate need beyond the size of truncate. But for xfs, it's passed. This test is base on test 255. > > With 213 I see it working to Windows, and to Samba test 213 also works > but only if "strict allocate = yes" is set in smb.conf (I just > verified it on the buildbot) > > > On Sun, Aug 2, 2020 at 9:55 PM Xiaoli Feng <xifeng@xxxxxxxxxx> wrote: > > > > Hello all, > > > > Recently when I'm investigating the xfstests generic/213 generic/228 > > failures for cifs. > > Found that fallocate can't change the cifs disk space usage.
