update: i manage to remove and recreate this pool, no problem with reboot… but GUI still complaining that
[EFAULT] Failed to stop docker service: [EFAULT] Failed to umount dataset: Dataset FastPool/ix-apps not found
i can’t nor unset or change pool. What i can try? I see a similar situation on this thread, and according to what this guy say, uploading conf file will raise again the error
