Hi, Experts I do the copying test with 2-nodes cluster under ctdb mode. A win2k3 client copies a big file to the share through the public ip of the master. During the copying, I reboot the slave node forcely. Then, the copying through the public ip of the master pause for about 10 sec. I wonder the ctdbd disturb the smbd. How the ctdbd communicate withe the smbd. Is the copying disturbed during the ctdbd recover? And how long is the smbd downtime? What is the factor of the downtime? e.g. node number, the stress on the master? -- Best Regards. Yu Liao
