Hello
Since I've enabled replication between a remote server and one of my VM I notice a constant increase of storage. In fact, when I discovered it when I reach 100% of my Thin-provisioning capacity on the data pool. So after reading a couple of threads, I found that I need to enable the Discard option and do 'fstrim' command inside the guest.
However, as there's continuous sync, the size increase around 5GB by hour which makes it necessary for me to rerun the command every 4-6 h. Is there a way to automatically free unused storage except with a cron job.
I'm also wondering about the impact on my hardware which is an NVMe and especially about lifespan.
Below VM config:
Below storage.cfg
