HDD size for this VM is set t o120GB.
Proxmox 4.3 with simple local ext4 disk as a storage, but the same situation is on 5.3 with lvm-thin dedicated disk.

Where did 129GB came from? Is this a bug?

GB vs. GiB

120 GiB * 1,024 * 1,024 * 1,024 = 128,84901888 GB ~ 129 GB

Does Proxmox state disk size in GiB?

 

[hanzfritz85]

size increment is in GB

Dear LnxBil,
Can you please add more info to your answer? I got that Proxmox storage is sized in GiB, but I can't find it in documentation. And why size increment clearly states GB. Is this not the case where all the units should be the same?

 

[hanzfritz85]

Sorry, should have spent more time on that.
Yes, disk is created with GiB units.
Thank you!
