Hi all, I'll ask help here as my googling just made me more confused than before.
I have a zpool raid5 of 18TB x 3 HDD. In theory, accounting for redundancy, there should be 36TB available and that's correct.
The issue is that when allocating a VM disk it allows me to go as far as 26TB, and when it's done creating it the 26TB image will take the whole reported 36TB. I assumed that it was an incorrect TiB vs TB report but 36TB is 32TB, and even accounting for filesystem and stuff it's still missing 6 or more TBs.
I'll attach both VM Disk screenshot and Pool usage. Can you help me understand if there is some overhead i'm missing? Thanks in advance for your help.
