Feature Request: Easy Change Failed drive in Proxmox

[weconnect]

Hello

i would like to request this feature below.

make a easyer way to change a failed ZFS drive from the GUI.

Background​

Currently, replacing a failed ZFS disk in Proxmox VE requires following the CLI-based guide documented here: ZFS on Linux – Change Failed Device. While this procedure works well for experienced administrators, it can be intimidating and error-prone for less technical users.

Proposal​

Introduce a user-friendly GUI workflow for managing failed ZFS drives directly within the Proxmox VE interface.

Suggested Workflow​

1. Navigate to the ZFS Pool
   Within the Proxmox GUI, select the relevant ZFS pool from the storage overview.
2. Identify the Failed Drive
   • A button such as “Failed ZFS Drive” should be available in the pool view.
   • Clicking this button automatically selects the failed drive.
   • Alternatively, users can manually select the affected pool and drive.
3. Take Drive Offline
   Once selected, the GUI should provide an option to put the drive into offline mode, ensuring it can be safely removed without disturbing the pool.
4. Replace the Drive
   The user swaps the failed physical disk with a new one.
5. Automated Recovery
   After insertion, the system should:
   • Automatically copy the partition layout from a healthy drive in the pool.
   • Start the resilvering process, rebuilding the missing data onto the new drive.

Benefits​

• Accessibility: Makes ZFS drive replacement manageable for non-CLI users.
• Reduced Risk: Minimizes potential user errors during a critical recovery operation.
• Consistency: Aligns with the intuitive GUI-first experience that Proxmox VE strives to deliver.

EDIT: submitted the same request at bugzilla: https://bugzilla.proxmox.com/show_bug.cgi?id=6698

Hej Tobias,

So, you're requesting that the system should work as smooth as hardware raid
Have you looked into zpool autoreplace property? I haven't, but from what I've read, this could already be what you asked for. Remove the drive from the slot, plug in another one and it just works.

Hello @LnxBil

yes it looks like it but would be good if we can toggle it from the proxmox gui
