very odd issue with storage space?

[killmasta93]

Hi,
I was wondering if someone else has had this issue before. So recently got an alert about 83% used in storage so I checked and i saw the local-zfs storage was fine, but then i looked closely and saw that the storage was 500gigs, not sure why if i have 4 disks of 1tb. I did create another storage called vmbackups with another proxmox hosts sends using pve-zsync to that storage but not sure how it got confused there.
Thank you

you currently have one zpool - rpool
on that you created a dataset rpoo/vmbackups which uses 965 G
This gets counted to the used space of rpool (because it is on the same disks)

I hope this helps!
