Earlier in the thread someone brought up aggregating network ports. I ended up buying an Intel Quad Port PCI-E 4x card for my server. A little bit of configuration in FreeBSD and on my Cisco switch, and now:

Also, you're welcome.
I believe it was me who mentioned LAGG, I'm running it with a dual port NIC, because it's in a low-profile pci-express port.

Slowest updates ever, we're talking 5-6months between the last beta release and last weeks RC's. Between that time serious bugs with LSI hardware that forced people to compile their own. The developer moved and the project kind of stopped for a while the relocation was taking place/new business with unRaid was being set up.

Replace the stock ui with SimpleFeatures and its quite nice.

Besides that 5.0 has been stable for me, plugins work (sabnzbd/sickbeard) well, and the new webui plugin should be stock.

This is the only reason I stick to LVM on top of a bunch of mdadm arrays. Until I ran up against the 16TB ext4 limit (that I didn't know about when I started with it), it was a simple matter to add a drive to the machine, expand a RAID array, and expand my LVM pool.

You can resilver existing vdevs, which is basically doing a kind of dangerous 1:1 replacement of each drive in the vdev. If you have a 6-drive RAID-Z2 vdev made of 1TB drives, you could individually resilver each drive with a 2 or 3TB drive and "grow it".

Or, you can plan to expand in terms of vdevs. My server was built around 6-drive RAID-Z2 vdevs, so I just bought 6-drives at a time to expand until my chassis was full.

If I lose another, it's going offline and I don't care how much the people here want their data. I have backups on another smaller NAS but I don't want to deal with giving them access to that and then merging the changes later.

It can be done if softward/firmware permits, Linux software raid has this capability. The trouble is that it requires a complete rebuild.

Add disk, tell it to use the new disk. Can use it while it resyncs the data.

to add to the RamChat, I have a 16tb ZFS volume and 8GB of RAM and I have no kernel panics or performance issues and no swap usage even though I have it configured to have an additional 8GB swap file available in FreeNAS.

Your mileage may vary, but 1:1 is definitely more of a recommendation than a requirement, at least on a consumer home storage level which seems to be where most people are headed in this thread.

I would do 1:1 in a production environment where there are more than (in my case) 3 simultaneous users of the storage, but not on a thing where we are all basically just using the thing to stream porn to our Boxxee.

Non-ECC RAM is hit-or-miss, so you might as well give it a try with what you have. Also, I hear that Windows (home server) is a bit more forgiving than the linuxy systems with regard to non-ECC RAM.

I think some people might confuse how an OS could "handle" certain kinds of memory failures better than another with an OS is loaded into a different part of memory than another with different memory access patterns that are more statistically likely to be affected by most memory failures in non-ECC DIMMs. Aside from research OSes that explore cryptographically secured execution contexts or something where every other memory segment is encrypted or something, nothing really modern OSes do that'll inherently make one more or less susceptible to memory defects aside from just using less RAM or something.

I used to recommend UNRAID to everyone but based on the frequency of updates as Viktor said, I dont. V5, which supports a lot of things modern raid systems do has been in beta for YEARS with a lot of crippling bugs. It also costs money, 120 dollars if you want the OS that supports more than 6 discs, 70 if you want the 6 and below setup. V4 which is what I am on works fine, but I want to upgrade my array size soon and do not plan on shelling out for the more expensive license.

Really at this point I'd wait and see how Windows Storage Spaces shakes out since it does parity protection similar to unraid.
