I have been reading the forum all day and I think I have a handle on this, but I want to run it by you guys before I do this. I have 3 drive 250g and 2 500g. The 250 and one of the 500's is empty and ready to be cleared and formated. The other drive is formated xfs and has about 170g of data on it. My plan was to setup the empty 500g to parity drive then add the 250g to the array. Then mount the 500g with data on it, copy the data to the array the add that drive to the array. Does this sound right. The only thing that worries me is can unraid mount an xfs drive? Right now the server is setup up with ubuntu server and only the 1 500g drive is mounted and being used.

 

I have an other question. Before I buy a pro key I would like to know how hard it is to get sabnzbd, sickbeard, and dropbox working. Is it possible to serve webpages off it to the local network? Thats not very important but I like having a full web/ftp server. That is why I originally went with ubuntu server over unraid. Back to browsing the forums.

If the 500GB drive that has data on it ONLY has 170GB of data then you can do it as you described.  If not then you will have to do it a slightly different way.

Sab and Sickbeard have a thread in the customizations forum dedicated to getting them running on an unRAID server.

Dropbox can also be done and has a thread here.

Yes, you should be able to install lighttpd or really any webserver you want and configure to your hearts content.

Ok ran in to a slight problem (my fault should have searched better) unraid cannot mount an xfs partition. Is there anyway to mount this drive with out losing data? Would I boot a livecd and copy the data to the non-parity drive?

You could, though is it was me I would probably do all this via another computer and copy over the wire so as to keep parity in tacked.

So put the drive in my main computer then copy over ethernet to the server.

 

Edited to add should a parity sync take 3+ hours with completely empty drives?

Every bit on the drives has a corresponding parity bit on the parity drive.  It does not matter if they have files on them or not, parity works on the bit level, not the file level.

 

If you could read your disks at an average of 75MB/s, and you have a 2TB disk (2000000MB), then it will take 2000000 / 75 seconds to calculate parity.

( 7.4 hours)  Most systems calculate parity at between 35 and 65MB/s.

 

You can do the math for your own disks.  If you are calculating parity in only 3+ hours, odds are you don't have anything larger than a 1TB drive in your array.

Ah yeah that makes sense. I forgot it calculates even for empty space. As of right now I only have a 500G parity and 250G data.
