Nếu một ngày nào đó bạn gặp lỗi Failed with result start-limit-hit thì nguyên nhân xuất hiện là khi một dịch vụ (service) trên hệ điều hành Linux đã vượt quá số lần khởi động trong khoảng thời gian nhất định. Hệ thống Linux thường áp đặt các giới hạn này để tránh việc lặp lại không ngừng của một dịch vụ khi có sự cố.
Thông báo này thường đi kèm với một số thông tin khác về nguyên nhân mà dịch vụ không khởi động được. Điều này có thể là do lỗi cấu hình, lỗi trong mã nguồn của dịch vụ hoặc một vấn đề nào đó khác liên quan đến môi trường hệ thống.

lines 319-360/360 (END)Cách giải quyết là bạn sử dụng lệnh reset-failed để clear lịch sử của hành động này.
systemctl reset-failed ceph-mgr@pve-03Bây giờ bạn có thể sử dụng hành động start lại như bình thường.
systemctl start ceph-mgr@pve-03Và dưới đây là kết quả.
