What is the implication of me using for example 1M volblocksize? This looks the best option in your spreadshit, speaking of space saving. All data would be written in chunks of 1Mb?

@Dunuin So in order to fix this issue in my environment, I should change the volblocksize. But can I just change it in the Storage configuration of my actual pools? How this affect my existing VMs? And I imagine that my VM-100 that is now using 30T instead of the 15T that was allocated, will...

I have ran the fstrim -av on all my linux servers last weekend, and it worked great on most of them, and I also enabled the fstrim.timer on every VM. Only on this VM id 100 I used as example it didn't worked. I repeated the command yesterday, and it ran all night along, and when I checked the...

I will wait for the next backup finishes and I will test this suggestion in the hollidays, then I get back to update this topic. Thank you @mira and @Dunuin !

@mira All my VMs are with the "discard" option enabled in it's configuration. Should I still run something manually in the VM?
