One thing you could do would be to verify that all the kernel modules are identical.  \
You can try running 'lsmod' to check that the servers have loaded the same set of \
modules, run 'modinfo' to verify the path to the module that was loaded, and then \
compute a checksum of the kernel module to compare.

    Yes, I believe that something must be different; I just cannot find it. I 
    now have six OST systems. All were installed the same way; two work fine 
    and four do not. The rpm list:

    # rpm -qa | grep lustre
    lustre-osd-zfs-mount-2.12.6-1.el7.x86_64
    lustre-2.12.6-1.el7.x86_64
    lustre-zfs-dkms-2.12.6-1.el7.noarch

    # the mount command example:
    # grep lustre /etc/fstab
    fs1/ost1        /mnt/fs1/ost1   lustre defaults,_netdev_  0 0

    and all are the same on all six systems. I currently have ZFS 0.8.5 
    installed, but I have tried with ZFS 0.7.13, and the results are
    the same.
