All of my KVM linux guests use ext4 at this time and my storage is ceph rbd. I am not using LVM within the guests at this time. Now I know proxmox only handles the resizing of the disk, but how do you recommend handling the resizing of the file systems on the guests. Again, LVM is not involved and im not 100% sure how to handle this when using rbd.
 
Inside the guest you have to use OS specific tools for repartitioning, maintain filesystems etc. regardless which kine your virtual disk is.

For LINUX guests use e.g.parted in order to adapt the partition table to the new size.
