Create a block from one of the nodes using the following command:
./cvavahi.py set_blkid <block id> <node1 serial number> <node2 serial number> <node3 serial number>
<block id>is an unique, unused name for the block.
<node1 serial number> <node2 serial number> <node3 serial number>are the serial numbers associated with the nodes.
./cvavahi.py set_blkid My_New_Block XXXX123456 XXXX123457 XXXX123458
This command should set the block. (No messages will be displayed if the block is successfully set.)
If you see the following message:
Could not locate avahi node with serial number XXXX123456 please make sure cvlt avahi service is exported from this node.
Restart the avahi service on all the nodes using the following command:
systemctl restart avahi-daemon.service
Verify the output of this command and ensure that the services are successfully started.
