Đây là mô hình Active - Passive nên dịch vụ chỉ hoạt động trên 1 node duy nhất. Bạn có thể thử tắt node1 đi theo lệnh:

pcs cluster stop dc-k8snfs01

Hoặc khởi động lại node2 theo lệnh:

pcs cluster start dc-k8snfs02

Thân ái!

Đức cũng đã restart như sau:

pcs cluster stop dc-k8snfs02 sau đó start lại vẫn không có thây đổi. chỗ dc-k8snfs02 trạng thái phải Slave thì mới sync data với nhau. hiện tại downtime dc-k8snfs01 thì dc-k8snfs02 tự động lên làm Master và cũng tự động mount thư mục vào disk /dev/drbd0. nhưng dữ liệu không đồng bộ.

Như vậy phải kiểm tra:

  • Rà soát lại cấu hình DRBD
  • Firewall, SELinux (Đối với CentOS/RHEL)
  • Log của pacemaker (/var/log/pacemaker.log)
