[QuTS hero h6.0 Beta] QuTS hero h6.0 Beta Testing Suggestion - Qtier enhancement request — need ability to disable/remove Qtier and replace SSD tier

English Firmware
1

I’ve been testing the Quts Hero beta and overall the Qtier feature is very promising. The automated tiering works well and the performance benefits are noticeable. However, I’ve run into a limitation that significantly affects flexibility and future upgrades.

Issue

Once Qtier is enabled on a storage pool, there appears to be no option to:

  • Disable Qtier

  • Remove the existing SSD tier

  • Replace the SSD tier with a new SSD (for example, a larger-capacity drive)

This creates a problem when upgrading hardware. I currently have a new, larger SSD that I want to use for the tier, but the UI provides no path to remove the old SSD tier or reconfigure Qtier without destroying the entire pool.

Impact

  • Prevents SSD upgrades without full pool rebuild

  • Reduces flexibility for long‑term storage planning

  • Makes Qtier risky to enable during beta testing since it cannot be undone

  • Forces downtime and data migration for what should be a simple tier replacement

Requested Enhancements

  1. Add an option to disable Qtier on a pool
    Allow users to turn off tiering without deleting the pool.

  2. Add the ability to remove an existing SSD tier
    Similar to removing cache devices.

  3. Allow replacing SSD tier drives with larger ones
    A guided workflow (evacuate tier → remove drive → add new SSD → rebuild tier) would be ideal.

These improvements would make Qtier far more usable in real-world environments where storage grows and hardware gets upgraded over time.
