OpenStack Caracal : Manila का उपयोग कैसे करें2024/05/22

 

OpenStack साझा फ़ाइल सिस्टम (Manila) का उपयोग कैसे करें यह इस प्रकार है।

यह उदाहरण निम्न प्रकार से पर्यावरण पर आधारित है।

उदाहरण के लिए, स्टोरेज नोड पर एक साझा स्टोरेज के रूप में एक स्थानीय ब्लॉक डिवाइस को कॉन्फ़िगर करें और इसे इंस्टेंस पर उपयोग करें।
इसलिए, इसके लिए स्टोरेज नोड पर एक निःशुल्क ब्लॉक डिवाइस की आवश्यकता है।
