comment ZFS: How do you restore the correct number of copies after losing a drive?
The scary thing about those sorts of experiments is that they're great for telling me a setup will fail immediately or at least quickly. They're not so great for telling me that a setup will fail occasionally. In any case, it's not clear how you bring back a pool that has a failure; I tried setting up a pool like this with three sparse files and removing one of the sparse files seems to be fatal to the entire pool. zpool replace won't replace the failed file, zpool scrub stalls at 5% (and these are very small pools), and the error page at illumos.org/msg/ZFS-8000-5E isn't optimistic.

comment How do I turn my DD-WRT router in to an access point?
Step 2 is probably wrong; the asker already has a router installed and they just want to have wireless devices access the network. Turning DHCP off here is what's needed, not turning it on and definitely not configuring DNSmasq on the access point. Bridge mode is something else entirely and is unrelated to the question.

comment Can you add two non-mirrored disks to a zfs pool?
3.2.0-40-generic #64-Ubuntu, but does it matter? I thought most zfs admin stuff is similar or identical across platforms.

@USDMatt - yes, that's exactly what I'm trying to do.

Can you guys be more specific about what's hard to understand? After thinking about it, I still can't figure out why it's not clear.

comment Best practices to set up laptop with wireless and wired interface/NIC over DHCP?
One is fast and one is slow. The fast one isn't always connected, though. From another machine to the laptop in question, it'd be nice to just connect to a single name and just get the fastest thing currently working.

comment How to have ZFS make snapshots of a directory only when files are changed?
You probably have to miss some changes. If you literally want to do a snapshot on every change, you'd have to create a snapshot every time a block was written.

comment ZFS: How do you restore the correct number of copies after losing a drive?
The problem is in @jlliagre's answer - the pool is dead if it loses any device. The fact that the pool still has enough ditto blocks doesn't seem to matter. Any way around that?
