Hello, fellow proxmox users, this is my first thread. I hope you guys are doing well in this pandemic. So I bought this Dell 720xd 2u 72tb+320gb server last month and decided to configure this week and chosen proxmox. I configured everything and added the raid 5 storage to the proxmox. Now I can't add more than 16tb HDD in a single drive to KVM guest ubuntu. Can you guys tell me how can I solve this? if there's any workaround?

Thanks, everyone :)
 
I guess you use ext4 as file system? If so, maximum ext4 file size is 16TB. You do not run into such limits if you use lvm or zfs.

Another thing is I used hardware level raid 5 on Dell 720 xd system. should I remove the hardware level raid and do zfs pool on proxmox?
