Symptoms 

• The following error occurs on an attempt to add a SolusVM Slave node that was connected to another Master before:

  SVM_ERROR: Volume Group not found

Cause

Old SolusVM Master IP address is specified in the /usr/local/solusvm/data/allow.dat file on the Slave node.

Resolution

Note: make sure that the SolusVM Master version matches the version of SolusVM on the slave servers.

1. Connect to slave node via SSH.
2. Remove the file that contains information about the old SolusVM Master IP address:

   # rm -f /usr/local/solusvm/data/allow.dat

3. Restart web service:

   # service lighttpd restart && service svmstack-nginx restart

4. Use the data from /usr/local/solusvm/data/solusvm.conf to connect Slave Server to the Master Node at SolusVM > Nodes > Add Node.
