📈 Changing volume size (Scalable)

📌 Introduction​

Scalability in Block Storage Volume refers to the ability to increase (or adjust) the size of a storage volume as needed, without the need to recreate the disk or manually migrate the data.
This allows applications to grow continuously, with minimal impact and without significant interruptions.

🚀 Benefits of scalability​

  • 📈 Growth on demand
  • ⚡ Avoids data migration
  • 🔄 Reduces downtime
  • 💰 Optimizes costs
  • 🔧 Operational flexibility

📌 Best practices​

info

The listed commands refer to the Linux operating system (Ubuntu).
Check equivalent commands for other distributions or operating systems.

  • Validate with lsblk before and after expansion
  • Use /etc/fstab for mount persistence
  • Monitor disk usage (df -h, du -sh)
  • Plan growth to avoid impact in production
  • Test in staging environment before production

⚠️ Points of attention​

  • Not all systems support volume reduction easily
  • Perform backup before any critical expansion
  • In critical environments (e.g., databases), validate I/O impact
  • Check filesystem compatibility

🔧 Steps to expand the volume​

1️⃣ Expand the volume on the platform​

  • Access the dashboard
  • Go to Volumes
  • Click the three dots (...) of the volume
