Hi, Didi Another question about glusterfs, I only used host1, host2 and host3 as gluster cluster, see: ``` [root@vhost2 ~]# gluster pool list UUID Hostname State b30d556d-73f9-4d63-8bc6-8ee541684b9c gs3.yhmk.sg Connected 2eb2f9fe-0237-4825-bf89-facc9d99534a gs1.yhmk.sg Connected c6e85a13-5186-4433-a3c8-0284f826361d localhost Connected ``` But, why I run `gluster pool list` on host4, the result is: ``` [root@vhost4 ~]# gluster pool list UUID Hostname State c6e85a13-5186-4433-a3c8-0284f826361d gs2.yhmk.sg Disconnected 2eb2f9fe-0237-4825-bf89-facc9d99534a gs1.yhmk.sg Connected b30d556d-73f9-4d63-8bc6-8ee541684b9c gs3.yhmk.sg Connected 4259036b-f4db-4d89-bb88-4dcf3c5f882c localhost Connected [root@vhost4 ~]# gluster volume list data engine vmstore ``` It's strange, why the host4 in the cluster, and can check the volume info?
