Missing space - 50ish gigs

[travalon]

Just started with freenas and have only attached 2 500gig drives so far. I mirrored them and now freenas reports they are only 452gb in size. I know there is 2 gigs of swap on each drive but where did the other 46 gigs go?

Hope this works

To the lying sacks of cr@p that are the marketing departments at hard drive manufacturers.

Seriously, been covered many times, here and everywhere else.

I guess we're fated to see this question at least once per week.

You kidding? If it were that rare I'd go party!

If I had admin rights I'd close this thread with the comment "use the search feature in the forum... it won't bite.. I promise".

I see my acerbic response about hard drive mfr marketing departments got killed by a moderator already. Nice.

Too bad they don't kill posts that have been asked before just hours before! Not this thread but there was another where the same exact question was asked just hours later.... really lame.

jgreco, your post was caught by the spam filter, not sure why since those links seem pretty innocuous.

 

[jgreco]

Okay, maybe I didn't notice that and jumped to the wrong conclusion. Still, you would think a spam filter would be less tetchy about posts from someone with 20 months and over a thousand posts.

I thought it was an awesome chance to take a pot shot in the direction of the HDD mfrs.

Yeah, this spam filter has a slight tendency toward false positives, unfortunately. Usually it's lots of identical log entries that triggers it.

It did it again to me in another forum. Ironically it lets me say "Barbra Streisand", but maybe that's only profanity if you're a South Park fan (see scene near end of the movie).

Ok I read this earlier http://forums.freenas.org/archive/index.php/t-8407.html and this http://forums.freenas.org/archive/index.php/t-1577.html and these http://forums.freenas.org/archive/index.php/t-7704.html, http://en.wikipedia.org/wiki/Gigabyte (Idon't understand it) ,a google search on 1000 vs. 1024 , http://www.disk-space-guide.com/size-units.aspx and I still don't quite get it. I always knew there was a difference because of 1000 vs 1024......Nevermind I just can't get my calculator to explain it to me.

So - 1000KB x 1000MB x 500=500,000,000KB
and
1023KB x 1024MB x 500=524,288,000KB

then if I divide the Manufacturers math 500,000,000 by mine 1,048,576 (1024x1024) , I should get the real capacity 476.83ish. Freenas shows 452.8 +2 in swap=454.8GB. where did the other 12 gigs go?

Or feel free to just ridicule me. Oh wait you do. I don't accept the answers I've found especially if I don't understand most of what they are saying. I even found a post about 1/4lb hamburgers being associated with actual drive capacity. So would someone please explain in laymans terms why HDD space available/reported is different than what we believe we bought. Also once you've explained it to us maybe submit it to be a sticky someplace prominent like Freenas4noobs (Oh wait that's where I started). Yea a sticky as opposed to dead links or redirects to discontinued blogs.

noobsauce I did read your manual thanks for the effort put into that.
