Ubuntu on Hyper-V and VHDX

[ForumBot]

I have a setup where I will run a Ubuntu Server on two VHDX disks. System 50GB and Data 4TB. They are located on a mirrored Storage Spaces Pool and are dynamic expanded.

During the Ubuntu installation the system disk got created on first VHDX as a EXT4 on a LVM pool.

My question is if its a good idea to use LVM on linux, or just simpel EXT4 on system and / or data-disk. Just a “mkfs”, file system creation of the Data-disk to EXT4 result in a 60GB expanded VHDX-file.

“mkfs -t ext4 -E lazy_itable_init=1 /dev/sdb1”

I created the machine before I read about the “VHDX Block Sizes”. So maybe thats a reason… [http://www.altaro.com/hyper-v/understanding-working-vhdx-files/](http://www.altaro.com/hyper-v/understanding-working-vhdx-files/)

What are your thoughts? Regards, Sam

I'd rather do ZoL instead of LVM + Ext3/4.
