8 Yes, at least for the storage stuff, LVM2 can do much of this.
9 But my ideas go some steps futher, eg:
10
11 * mapping blocks instead of larger chunks
12 * defect management directly on block basis (w/o additional
13 stacking layers).
14 * distributed storages (not just disks, but several hosts)
15 * volumes attributes which let the volume manager decide how/where
16 to actually store blocks, eg.:
17
18 + mirroring: min/max number of copies, allowed device classes
19 + compression: allowed algos or grades
20 + encryption: ciphers, keys, ...
21 + reliability: hard/limit (eg. use "unstable" disks exceptionally)
22 + caching: allow some volumes to be cached on fast devices
23 ...
