you could also do the trick with zfs - just create an zpool on that loop device - this also gives you lz4 and gzip

- shmerl 9y agoYes, but ZFS is probably more memory hungry and somewhat an overkill just for compression alone. It's a pity simpler filesystems don't have transparent compression.
- matt_wulfeck 9y agoI'm not sure it's an overkill compared to the presented solution.
- keeperofdakeys 9y agoOne disadvantage of zfs in this case is that it uses its own caching layer, since it's basically an OS subsystem in itself. So on a memory constrained host (eg. rpi), you might have some issues with the zfs and linux buffers competing for RAM.
- trentnelson 9y agoLike NTFS has had for the last 20+ years? ;-) One of the benefits of NT's packet-driven I/O model (versus the UNIX synchronous VFS read/write blocking buffer I/O model).
- shmerl 9y agoBTRFS is now good for it, but having it in other filesystems would be useful too. Linux now supports some async I/O as well.
