Problem to add one node to cluster

 

Problem to add one node to cluster

Hi, everybody.

I have a three-node cluster with MC/Service Guard and LVM.

I want to add one node more, but I execute

cmcheckconf -v -C

cmapplyconf -v -C

and the output is

Adding node mtc1sgi4 to cluster mtc1sgi.
Protocol failure talking with cmclconfd on mtc1sgi4 (1) : File exists
Error: Unable to initialize Volume Group /dev/vgMESPSRP on node mtc1sgi4.
Check the syslog file on that node for more information.
cmapplyconf : Unable to apply the configuration

also in the syslog.log display

Unable to setup the volume group id for /dev/vgMESPSRP: File exists

Can anybody tell me how to resolv this problem

Thanks

Re: Problem to add one node to cluster

Hi,

There are couple of possibilities. There may be a vgid conflict. Generate mapfiles exporting the VGs with preview and -s option and find out the VGID and compare them with other VGs on all the nodes in the cluster.

On mtc1sgi4, there may be a group device conflict. If the kernel had already registered the group device then this error may result. A reboot should clear up this issue.

Try manually activating the vg vgEMSPSRP and see what happens.

You may be disappointed if you fail, but you are doomed if you don't try
