Storage Guide

A practical, step-by-step walkthrough to create, attach, detach, and manage block storage volumes. This guide complements the overview at Storage.

1) Create a Volume

  1. Open the dashboard and go to Menu → Block Storage → Volumes.
  2. Click "Create Volume".
  3. Fill out the form:
    • Name (e.g., data-volume-01)
    • Size (e.g., 20 GB)
    • Optional description
  4. Submit to create the volume.
Instance Create

Tips:

  • Choose a size that fits current needs; resizing may require platform support and maintenance windows.

2) Attach the Volume to an Instance

  1. In the Storage list, find your volume.
  2. From Actions, choose "Attach to Instance".
Instance Create
  1. Select the instance to attach to.
  2. Confirm.
Instance Create

After attachment, log in to the instance and format/mount the block device. Example for Linux (replace /dev/vdb with your device):

# Create filesystem (only once per new volume)
sudo mkfs.ext4 /dev/vdb
 
# Create a mount point
sudo mkdir -p /mnt/data
 
# Mount the volume
sudo mount /dev/vdb /mnt/data
 
# Optional: add to /etc/fstab for persistence
# Find the UUID and add an entry
sudo blkid /dev/vdb

3) Detach the Volume

  1. Unmount the device from the OS, if mounted, to avoid data loss.
  2. In the dashboard, open Services → Storage.
  3. For the target volume, select "Detach Volume" from Actions.
  4. Confirm detachment.
Instance Create

4) Delete the Volume

Only delete volumes you no longer need. Deleting is irreversible.

  1. Ensure the volume is detached.
  2. From Actions, choose "Delete Volume" and confirm.

Snapshots and Backups

  • Snapshots: Create a point-in-time copy of a volume before risky operations. Restore as needed. See Snapshots.
  • Backups: Schedule periodic backups for disaster recovery. See Backups.

Troubleshooting

  • Attach/Detach stuck:
    • Ensure the instance OS has unmounted the device and no processes are using it.
    • Try again after a short delay; check notifications for progress.
  • Volume not visible in OS:
    • Verify the device path (e.g., /dev/vdb) and refresh lsblk.
    • Check that the attach operation completed successfully.
