Re: [lustre-discuss] OST mount issue
I see that you are using dkms version of lustre module. I would check that, it is possible that the dkms build trigger a client-only build of Lustre ? (missing deps, etc...) Could you check the list of Lustre modules built and installed by dkms between the 2 working OSSes and the 4 others?

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.

Re: [lustre-discuss] OST mount issue
Hello Steve, This message appears when you are using Lustre modules built with only client support, with server support disabled. This message is quite new and only appears in very recent Lustre releases. What Lustre version are you using, this error does not exist in 2.12.6 as far as I know. Could you double check the Lustre version and RPMs you installed on that host, compare with the other and ensure they are the same? Could you simply try: 'modprobe mdt' and see if that works? Check also: 'lctl get_param version' Aurélien Le 25/04/2021 15:10, « lustre-discuss au nom de Steve Thompson » a écrit : CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you can confirm the sender and know the content is safe. 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.
