As far as I know, there is still one big problem with BTRFS for Proxmox: Running a thin-provisioned VM (i.e. QCOW2) on top of a BTRFS filesystem on top of a regular spinning-rust HDD produces **extremely bad** performance. Running the identical system but on ext2/ext3/ext4 produces the

Well I almost do it, 'cause one of feature I appreciate in btrfs is the hability to increase or decrease disk size. I know LVM can do it as well, but LVM are always on top whatever X Filesystem. So do you have more layers... Btrfs is direct into the device. Or am I wrong?! 2016-02-02 11:30
