      Description

      Running llmount.sh with FSTYPE=zfs fails with "mount.lustre: lustre-mdt1/mdt1 has not been formatted with mkfs.lustre or the backend filesystem type is not supported by this tool".

      This was seen while working on LU-3606 (ZFS). The goal is to create a very small working ZFS instance for dev purpose. This is combined MDT/MGS. Changing test-framework.sh to using mount.lustre binary worked for me. This may just not be a bug. I am raising it to understand if this is really a bug or something to do with my environment. What are the difference of passing -t lustre vs using mount.lustre. I thought they ultimately boils down to same.

       

      This fails

      This was fix by changing test-framework.sh

      diff --git a/lustre/tests/test-framework.sh b/lustre/tests/test-framework.sh
      index 31e7ec3..a363fbb 100755

       else
      + #do_facet ${facet} \
      + # "mkdir -p $mntpt; $MOUNT_CMD $opts $dm_dev $mntpt"

       fi

      Essentially changing from using mount -t lustre to using mount.lustre binary makes it work.

      My e2fsprogs version

      # rpm -qa | grep e2fsprogs-1
      e2fsprogs-1.45.2.wc1-0.el7.x86_64

      My setup and compile lustre

      # sh ./autogen.sh
      # ./configure --enable-client --enable-server --disable-ldiskfs --with-linux=/usr/src/kernels/3.10.0-862.9.1.el7_lustre.x86_64/ --with-zfs=/root/zfs/zfs/zfs-0.7.12/ --with-spl=/root/zfs/spl/spl-0.7.12/
      # make -j2
      # make install
