system-config-lvm

[Chris Murphy]

This doesn't answer the original question, but here are two comments.

a.) Even a few, let alone many, file system resizes make the file system inefficient. This goes for both ext and XFS. (Btrfs is in a different category because it allocates in chunks and when a fs is resized, a drive is added or replaced, or removed, the chunks are relocated. Resize is just a variation on a balance.) The better option, is to fix the size of the file system at the largest it would ever practically be in its lifetime, using LVM thin provisioning. And use fstrim occasionally, instead of resizing the file system.

b.) A non-GUI option, that establishes a fairly consistent vernacular among various storage technologies (md raid, LVM, btrfs), is the system-storage-manager package. Its syntax is more btrfs like, rather than the multi-step and rather esoteric commands needed for LVM. For example:

There's a pile of really useful info here. It recognizes LVM and btrfs snapshots, LVM raid (in contrast to LVM on md raid), thin pools and volumes, btrfs subvolumes, and so on.
