[lustre-discuss] OST mount issue

Two CentOS 7.9 hosts with kernel 3.10.0-1160.21.1.el7.x86_64, using ZFS 
0.8.5 with lustre 2.12.6. One system works perfectly, whereas the second 
host fails to mount the OST, with this message from the mount:

mount.lustre: mount fs1/ost1 at /mnt/fs1/ost1 failed: Invalid argument

and this confusing message in the log:

Apr 25 08:56:18 fs1 kernel: LustreError: 27722:0:(obd_mount.c:1597:lustre_fill_super())
 	This is client-side-only module, cannot handle server mount.

Can someone please point me to the error? BTW, the two systems were both 
kickstarted from the same repo, so as far as I can tell, they are 
identical. The lustre RPMs were installed from the server repo.
