WHS Style "drive pooling" now in Linux

[criccio]

Seems the Linux community has caught up with WHS' drive pooling feature.

The free NAS OS Amahi already implemented it as well:

Anyone willing to try it out?

Nice to see this coming along, however i would not trust any data to it.

Even the author says that its not production ready and only a proof of concept.

Sounds interesting until you read how it works.

I'm fine with mhddfs.

Yes this is still something ZFS lacks. It would be great if you could use RAID0 and insert all kinds of disks with different capacities; like you can with ZFS. And then use copies=2 or copies=3 on directories you want redundancy for, and can set the level of redundancy per directory. That would be awesome.

It already works to correct BER / corruption; but it can't handle a complete drive failure; that would lead to inaccessibility to the entire pool; even when all data has at least copies=2. This is a design limitation and i hope ZFS will support this kind of operation in the future; technically it is already possible with the existing on-disk format.

Any storage hackery should at least be done through fuse, and not depend on Samba .
