Lustre file system names cannot exceed 8 characters in length, but “scratch12”
is 9 characters. Try changing the fsname to a smaller string. You can do this
with tunefs.lustre on all the storage targets, but I can’t remember if you need
to use --erase-params and recreate all the options. Alternatively, reformat.

this is weird. lnet module is running. There is no firewall and OSSs and
MDS are on the same subnet.
but I Cannot connect to port 9888.
There is anything which changed in Lustre 2.10.0 related to lnet and TCP
ports that I need to take care of in the configuration ?
