15 Interestingly, after feeding LVM NAS to my search engine, one of the first
16 results was a Qnap user forum thread which reads that Qnaps use LVM. It
17 makes sense, since they most likely use a “normal” linux software RAID
18 underneath, and LVM is then the best way to dynamically manage the space on
19 top of that.

21 While ZFS has the same pooling feature as LVM, meaning you can bunch several
22 disks together to create a JBOD, it has one big disadvantage over LVM: you
23 can grow a pool, but not shrink it. Actually, while reading up on stuff for
24 this thread, I learned that these days it is actually possible to remove a
25 mirror vdev from a mirror-only pool (a mirror can technically also be a
26 single device). But according to
27 https://utcc.utoronto.ca/~cks/space/blog/solaris/ZFSWhyNoVdevRemoval
28 it’s not perfect either.
