मोंगो अपवाद

Question

हाल ही में मेरे पीसी पर कुछ स्टोरेज समस्याएं थीं इसलिए मैंने पत्रिका के आकार को कम करने के लिए mongo.conf फ़ाइल को बदल दिया। जब मैं नए परिवर्तन मैं (परिवर्तन यह सिर्फ ठीक काम करता है) के बिना यह त्रुटि प्राप्त साथ मोंगो चलाने का प्रयास ये लाइनें जो मैं में डाल रहे हैं।

mmapv1: 
    smallFiles: true 

हालांकि, हर बार। क्या आप मुझे बता सकते हैं कि समस्या क्या है?

Shutting down the full-time diagnostic data capture subsystem.

Answer 1

मैं निर्देशिका /data/db/diagnostic.data को हटाने की कोशिश करेंगे।

तुम भी विकल्प के साथ मोंगो शुरू करने से नैदानिक ​​डेटा संग्रहण को अक्षम कर सकते हैं:

setParameter: 
    diagnosticDataCollectionEnabled: false 

Answer 2

मैं एक ही समस्या थी के बाद MongoDB में विफल रहा है जब HD 100% तक fulled किया गया था। यहाँ लॉग है:

Shutting down the full-time diagnostic data capture subsystem. 

मैं kill एड mongod और नैदानिक ​​फ़ोल्डर की सामग्री को मंजूरी दे दी:

> rm -f /var/lib/mongo/diagnostic.data/* 

बाद मोंगो लॉग को फिर से प्रारंभ से पता चला है:

और मोंगो ठीक था।

Answer 3

यदि आप नोडजेज़ का उपयोग कर रहे हैं, तो अपने सर्वर कोड में डीबग मोड को अक्षम/निकालने का प्रयास करें।

कदम:

1. rm -rf /{your_db_name}/diagnostic.data/
2. हटाना होगा या mongoose.set('debug', true);
3. बाहर टिप्पणी पुनः आरंभ मोंगो और नोड सर्वर
