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.
