Issue enabling meta data mirroring

[Usman Aslam]

We've configured a buddygroup for metadata mirroring but when trying to enable it we get the following "Invalid Argument" error message.

# beegfs-ctl --mirrormd
Operation failed on server: beegfs-mgmtd HOSTNAME [ID: 1]; Error: Invalid argument
See the server's log file for details.

I've looked through all docs but cannot find any required arguments or their syntax.

Any suggestions?

Thanks,

I'm getting the same issue on a clean install of 7.1.4 on Cent7.  I have 2 metadata nodes online, they show Good consistency, and they are virgin.  The mgmtd log shows the metadata nodes coming online, so why does it think there aren't any metadata nodes???

Almost forgot...yes, both metadata servers are in a buddy group.

[root@silomon ~]# beegfs-ctl --listtargets --nodetype=meta --mirrorgroups --state

Did you ever find the root cause of this?
