Expand Storage of ZVOL Guest VM Doesn't Recognize Disk Size Change

[Stux]

You need to resize the VMs filesystem inside the VM.

Which is FS dependent.

This is how to do it for an LVM system:

HOWTO: Resize a Linux VM's LLVM Virtual Disk on a ZVOL

If you have a Linux VM, which uses the LLVM filesystem, you can easily increase the disk space available to the VM. Linux Logical Volume Manager allows you to have logical volumes (LV) on top of logical volume groups (VG) on top of physical volumes (PV) (ie partitions). This is conceptually similar to zvols on pools on vdevs in zfs. This was tested with TrueNAS-CORE 12 and Ubuntu 20.04. Firstly, there are some useful commands: pvs - list physical volumes lvs - list logical volumes lvdispl…
