I am attaching the log file for the same after restart. Thre behaviour looks abnormal. A mgr restart is not required for the schedule to get triggered.

The schedule was suppose to start at 2023-10-04T07:20:00 but it started at 2023-10-04T08:20:00 seems normal behavior to me the schedule starts countdown for 1h from 2023-10-04T07:20:00 and created first snapshot at 2023-10-04T08:20:00 > > Any input w.r.t the same will be of great help. > > Thanks and Regards > Kushagra Gupta -- Milind _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
