Comment 5 Vasishta 2022-05-13 14:14:40 UTC 
- Tried with mirroring configured between two clusters with 100 images with snapshot scheduling set for 2 minutes with IOs on all the images.
(rbd_mirror_die_after_seconds)
- Tried different time duration - 10, 15, 30, 60 minutes, 8 hours
- Tried with different duration on two clusters.
- With above points, observed over 28+ hours
- Note - rbd-mirror daemon needs to be manually restarted each time in standalone cluster as automatic restart won't happen.

With above operations, It was observed that mirroring daemon used to stop each time and issue of rbd-mirror daemon not getting stopped has not been observed.

Moving to VERIFIED state.
