Hmm, I checked tonight and I see the same (correct?) behavior in your tree. >> And, device_aliasing check is still failing, since it does not understand >> test_opt(). Probably it's the only case? Again, in your tree (I had to use a git version of f2fs-tools to make device aliasing work - maybe time for a release?) ;) # mkfs.ext4 /dev/vdc # mkfs/mkfs.f2fs -c /dev/vdc@xxxxxxxx /dev/vdb # mount -o noextent_cache /dev/vdb mnt # dmesg | tail -n 1 [ 581.924604] F2FS-fs (vdb): device aliasing requires extent cache # mount -o extent_cache /dev/vdb mnt # mount | grep -wo extent_cache extent_cache # Maybe you can show me exactly what's not working for you? -Eric
