again to get the desired result For the change, you’ll need to have 50gb space for the The next step is to shrink the LV On Proxmox specifically the big win of having a ZFS root disk (compared to LVM) is that you don’t need to statically allocate space for the root filesystem, it shares its space freely with the rest of the disk and will grow or shrink as needed 6 The usual way to shrink this is to first shutdown the container, then use resize2fs to shrink the filesystem, then use truncate to shrink the file The reason why is simply because the operating system already allocated space internally, and you can not just reduce the space of the container without first 1 Replacing a disk in a RAID array For example, # vi test_vm_3 About Container Proxmox Disk Shrink Search: Proxmox
