[Bug Report] Self-Build-Deployment: filesystem that will host /data/cubelet is on '/' (type: ext4), which is not XFS.

[Dafeigy]

Summary

In self-build-deployment, when running sudo ./install.sh, [one-click] ERROR: The filesystem that will host /data/cubelet is on '/' (type: ext4), which is not XFS.

Environment

• CubeSandbox version / commit: 0.2.0
• Host OS and kernel version: Ubuntu 22.04 & Linux 6.8.0-111-generic
• KVM info (modinfo kvm):
• Deployment mode: single-node
• Relevant component: one-click

Steps to Reproduce

1. Following docs\guide\self-build-deploy.md to perform Build the Release Bundle section and get the cube-sandbox-one-click-<version>.tar.gz
2. unzip the release bundle and run sudo ./install.sh
3. Errors:

[one-click] ERROR: The filesystem that will host /data/cubelet is on '/' (type: ext4), which is not XFS.
  Cube Sandbox requires the /data/cubelet directory to reside on an XFS filesystem.
  Options:
    1. Mount a dedicated XFS-formatted partition at /data/cubelet:
         mkfs.xfs /dev/<your-partition>
         mount /dev/<your-partition> /data/cubelet
    2. Ensure the parent path (/) itself is on XFS.`

Expected Behavior

Installation is completed successfully.

Actual Behavior

[one-click] ERROR: The filesystem that will host /data/cubelet is on '/' (type: ext4), which is not XFS.
  Cube Sandbox requires the /data/cubelet directory to reside on an XFS filesystem.
  Options:
    1. Mount a dedicated XFS-formatted partition at /data/cubelet:
         mkfs.xfs /dev/<your-partition>
         mount /dev/<your-partition> /data/cubelet
    2. Ensure the parent path (/) itself is on XFS.`

Additional Context

I think a simple solution, like using a loopback file which is formatted in xfs, may help in build-guide docs.

[kinwin-ustc]

You are right. For testing/experience purposes, creating a loop file and formatting it as XFS is the simplest approach. We rely on XFS because we depend on XFS's reflink mechanism to accelerate the creation of sandbox writable disks.
