inertz

Bukan. Baremetal server.

Rasanya soalan ni mahal, tanya kat expert exchange pun diaorg point ke redhat.

Salam, Mintak tolong sesiapa yang tahu atau biasa dengan HA dengan masalah ni. Aku tengah buat simulation NFS storage dengan HA. Setup ni mengandungi 3 biji cluster. Bila enable stonith untuk create disk fencing error yang keluar berkaitan registration key. *Error ni mungkin boleh dapat solution kat redhat punya portal, tapi kena subscribe la pulak. Harap ada sesiapa boleh bagi idea.
