Il disco è pieno, e non posso SSH all'istanza

Question

Viene visualizzato un errore durante il tentativo di SSH nella mia istanza. Mi dice di controllare l'uscita seriale della console. Da quello che ho capito dice che il mio disco non ha più spazio. Cosa faccio? Ho bisogno di SSH per cancellare lo spazio ma non posso SSH perché non c'è spazio!

Questo è quello che vedo:

Answer 1

sono possibili diverse opzioni per risolvere questo problema:

1. Check if your operating system supports automatic resizing: Se è così, utilizzando la console cloud è possibile modificare disco di root del VM e aumentare la sua dimensione. L'istanza della macchina virtuale può ridimensionare automaticamente la partizione per riconoscere lo spazio aggiuntivo dopo il riavvio dell'istanza.

2. Utilizzare Interactive Serial Console feature per accedere alla macchina virtuale e pulire il disco della VM o copiarli in un'altra memoria, se necessario in seguito.

3. Se si conoscono i dati che si desidera eliminare, è possibile configurare un startup script per rimuovere i file e riavviare la VM per eseguire lo script (ad esempio rm/tmp/*).

4. È possibile scollegare il disco persistente e collegare questo disco a un'altra macchina come disco aggiuntivo. Sulla macchina temporanea, puoi montarla e pulire i tuoi dati o copiarli in un'altra memoria, se ne avessi bisogno in seguito. Infine ricrea l'istanza originale con lo stesso disco di avvio. È possibile seguire la stessa procedura descritta in questo video per aggiungere il disco a un'altra macchina virtuale Linux, ma aggiungere il disco di avvio esistente invece di creare un nuovo disco.

5. Check if your operating system supports automatic resizing: Se sì, quindi creare un'istantanea del disco persistente, creare un nuovo disco persistente con dimensioni maggiori dallo snapshot. Infine ricrea l'istanza originale con questo disco di avvio più grande.
