It's in beta status right now, so you can try it out. There are already several plugins available, one of which being Transmission (torrents). On another note, FreeNAS 8.0.4-p1 was released 2 days ago. It addresses a critical Samba vulnerability.

I had no problems installing SABnzbd, sickbeard, couchpotato, etc on my freeNAS 8 box. I haven't tried a torrent client yet, however.

DrDork posted:It will certainly let you do torrent stuff. 8.x (including the stable 8.0.x) can use Transmission via a simple pkg_add command and some setup, and 8.2-Multimedia comes with it built-in. Not the most advanced torrent application, but it works. I stand corrected. I am assuming these can be installed easily without the CLI? Guess I will check them out to find out. Does anyone know how does the torrenting aspect affect ZFS? Will the tiny pieces of files being written all over the place affect its performance/function ? I would be concerned especially since ZFS has no defragging tools.

Through the ports directory you can have sbanzbd/rtorrent/screen up and running very quickly and the snapshots and scrubs can be automated through cron. Setting up a zpool is very easy. You lose the pretty web interface but if you use your server for more than just regular file serving you won't miss it (plus you can run fbsd 9 which has a newer version of zfs).

As someone who used to sperg about zfs performance, I just throw everything at it now and stopped caring. Rtorrent, sabnzbd, time machine for a few laptops, xbmc share streaming. It's fine. Really, it is. I got my biggest performance boost switching to a 5ghz dual band router in my apt complex where there are 100+ FiOS routers on 2.4 ghz.

DrDork posted:The plug-in system of FreeNAS 8.2 is supposed to let you do that without CLI use, but it's still very much in beta, so I haven't tried. I know setting up Transmission for torrenting takes all of 5 minutes and there are step-by-step guides for doing it. Using the CLI won't kill you, I promise. I'll definitely try, just that my unix / linux skills are severely lacking and am worried I'll bork the server. Hopefully those 8th grade MS-DOS skills will come in handy.

Can anyone convince me what to do with 8x 2TB drives in a ZFS setup? I currently have 5 of the drives in a RAIDZ1 setup and need a migration plan for existing data once I get 3 more. 1) 2x 4-drive RAIDZ1 groups in one pool. 2) 8-drive RAIDZ2 zpool. Exactly how much more reliable is option 2 here? I'm considering option 1 as it seems possible to migrate the existing data without needing more drives.

I'd suggest using nano instead of vi for the editing, though. e; if pkg_add is throwing some cannot connect errors, make sure you assigned a default gateway and nameserver in FreeNAS's web setup. If you don't, while FreeNAS will still happily work on your internal network, it won't be able to connect out to the rest of the internet properly.

In the first case, you lose half your data if two drives in the same RAIDZ1 die, in the second case, you can lose any two drives and still be fine (but then you lose everything if a third drives dies before you can rebuild)

The failure rate of disk drives at 5 years is 10%+. If you're using big arrays and identical drives (and thus similar failure patterns), you're living on borrowed time without Raid6 or better (ideally something with end-to-end data integrity like RaidZ2 on ZFS). RAID 5  RAID 6  This is on a big (20 drives) array, but you get the point. Also shitton of media errors simply go undetected in traditional raid setups. I don't even want to talk about non-parity raid levels. evil_bunnY fucked around with this message at 12:37 on Apr 16, 2012 |

I currently have 5 of the drives in a RAIDZ1 setup and need a migration plan for existing data once I get 3 more. I had an 8 drive RAIDZ1 pool for about 2 years. It used WD Green drives and had performance issues, and I had 4 drives die at different times. I eventually bought 8 WD Black drives and replaced each drive one by one, rebuilding the array 8 times in a row. I have never had an error or lost any data. ZFS is great.

I have a question regarding ZFS snapshots. I've scheduled the snapshots to take place at midnight every day and stay alive for 1 month. If I look at the snapshots it will only allow me to revert to the latest one. Say I wanted to revert 5 days ago, how does this work exactly?

DEAD MAN'S SHOE posted:Please explain what you mean by failure pattern; do you mean to say that drives of the same model will fail at the same time? Two drives of the same type made during the same production run with the same usage pattern in the same conditions (ex. in the same RAID array) are (possibly) more likely to fail at roughly the same time. So ideally you would want to have all your drives come from a different production runs to minimize the chance they will fail at approximately the same time (during rebuild). Of course this isn't all that practical and I don't think it's something all that many people do but if you want to min/max your array it's something you can do I guess.

What I do is maintain an internal drive on my desktop where I store the important stuff, and I have CrashPlan back up that poo poo to the cloud. My NAS stores another copy of that stuff and also all my perishable items.
