OpenStack Caracal : Cinder स्टोरेज का उपयोग करें (Multi-BackEnds)2024/05/22 |
|
यदि किसी इंस्टेंस को अधिक डिस्क की आवश्यकता है तो Cinder द्वारा प्रदान किए गए वर्चुअल स्टोरेज का उपयोग करना संभव है। यहां LVM और NFS मल्टी-बैकएंड के साथ वर्चुअल स्टोरेज कॉन्फ़िगर करें।

इस उदाहरण पर LVM बैकएंड के लिए, वॉल्यूम समूह [vg_volume01] का उपयोग करें। |
| [2] |
NFS सर्वर का आपके स्थानीय नेटवर्क पर चलना आवश्यक है, यहां देखें। |
| [3] | संग्रहण नोड कॉन्फ़िगर करें। |
