The specified cluster object MYCLUSTER could not be found

Hi,

I'm trying to install NCS on two SLES 11 SP3 servers, but I'm stuck on this.

I can install NCS on the first server, and create the cluster object in eDir. I can see the cluster object in iManager after that.

But when I try to add the second server, I get the error from the title, even selecting the cluster object on the selection window (i.e. not typing its name).

I've searched a lot, and read the documentation, but no progress.

By the way, both servers are OES 11 SP2; both of them was first installed on a test tree, and later moved to our production tree. And both of them was part of a cluster on the test tree.

The problem occurs, no matter which of the servers I install the cluster; when I try to add the second server to the cluster, I receive the error.

PS: I've opened this thread first on the OES-Linux forum.

It's been my experiencing, that simply removing nds and reinserting into a diff tree doesn't work well and usually not all the OES services work right afterwards.

I would've just rebuilt the server from scratch to be honest.

But let's see what changju or some of the others have to say. I'm sure there's a log file somewhere that will give more detail, I'm just not remembering off the top of my head.

Please don't post the same issue in multiple forums - pick the one which
best fits your issue.

Simon, I asked him to post in this forum since Changju frequents this and may be able to assist.

And since we're not allowed to move posts anymore ....

Re: The specified cluster object MYCLUSTER could not be foun

I know that someone should not post the same post in two forums. If I could delete the first post, or ask someone to move it here, I would have done it.
That's why I alerted it, so a moderator could delete the original post on the wrong forum.

Re: The specified cluster object MYCLUSTER could not be foun

To install a server into another cluster, you need to first remove it from the first cluster.

To remove a node from a cluster, the easiest way is to use /opt/novell/ncs/install/ncs_install.py with the "-r" option (available on OES11 or newer).

/opt/novell/ncs/install/ncs_install.py -r

It will ask you for admin dn and password. You can put them into a configuration file and use "-f" option to supply it to the command.

/opt/novell/ncs/install/ncs_install.py -r -f /root/ncs.conf

You can check the return value of the command and log information appended in "/var/opt/novell/install/ncslog" for results.

You can also manually remove all NCS related attributes to remove a node from a cluster.



Best regards,

Changju

Re: The specified cluster object MYCLUSTER could not be foun

Well, I tried to reinstall both servers, and insert them directly on the production tree. The result was the same; the second server complains that it cannot find the cluster object.
Could this be a bug?

More likely there are still pointers to the old cluster/tree
the command '/opt/novell/ncs/install/ncs_install.py -r' needs to have
been run while your servers were still a part of the test tree, otherwise
it can't readily see the old cluster.

So options as I see it:
1) Properly remove these servers from the production tree, then flush and
recreate them as new as per Kevin.
2) Properly remove these servers from the production tree, rejoin to the
test tree, run through the process Changju posted, then rejoin the
production tree.
3) Search all files on / on these servers for instances of your test tree
name, test cluster name, test system IP addresses, and correct them to
what you are attempting to create in the production tree. And hope that
this is sufficient.

But I reinstalled the servers from scratch --- all file systems formatted ---, and the old tree no longer exists, --- these servers was the only on it.
Where, in heavens, can this information be stuck???

Re: The specified cluster object MYCLUSTER could not be foun

Another thing that I'm observing is that when I try to create a new cluster object in yast2, after the first screen, where I type the object full DN, the master IP address, and the SBD device, the next screem asks for the proxy user configuration.

If I try to use the OES Common Proxy User (OESCommonProxy_ServerA.OrgUnit.Org), the password field gets emptied, and the wizard demands that I type its password. I remember that the last time I installed a cluster, this field was disabled when I selected the Common proxy user.

OBS: In the meantime, I tried lots of things, including adding a replica to these servers, but there's no change in the problem.

Re: The specified cluster object MYCLUSTER could not be foun

It's like a credential issue from your descriptions. Please check log file "/var/opt/novell/install/ncslog" for clues.

You can use admin credentials to install the cluster and assign NCS to use proxy users later on.

Changju

Re: The specified cluster object MYCLUSTER could not be foun

I'm pretty sure that's the point.

I searched a lot yesterday about it, and saw that common proxy isn't working in one of the servers. I tried things like the "move_to_common_proxy" to recreate the OESCommonProxy_ServerA object. The interesting is that it always says that the common proxy object doesn't exists and try to recreate it.

What about the SBD partition? It has a few bits of data in them and if you
happen to be reusing it......

I'm deleting it with NSSMU each time I give a new try.

What about the eDir cluster object(s)?

I wonder if when it got created, because the servers had their conf files with "old" information that maybe it populated the new eDir objects with the old tree stuff?

I suppose you could probably view the attributes and see if any old IP/Tree info is in there??
