[Lustre-discuss] Cannot mount MDS: Lustre: Denying initial registration attempt from nid 10.201.62.11 at o2ib, specified as failover

[Kevin Van Maren]

Okay, the local server is shown:
  Lustre: Added LNI 10.201.62.11 at o2ib [8/64/0/180]
  Lustre: Added LNI 10.201.30.11 at tcp [8/256/0/180]

But you specified that as a failover node:
  # tunefs.lustre --erase-params --param="failover.node=10.201.62.11 at o2ib,10.201.30.11 at tcp failover.node=10.201.62.12 at o2ib,10.201.30.12 at tcp mdt.group_upcall=/usr/sbin/l_getgroups" /dev/md10


As you surmised, you do not add the local NIDs, as those are added 
implicitly by Lustre.
Note that this means the first mount has to be done on the "primary" 
server, not the failover server.

Not sure what you mean when you say it worked before -- did you specify 
both sets on your mkfs command line?
