Sorry its not MSI - it is LSI
LSI MegaRAID SATA to be exact.

http://www.lsi.com/storage_home/prod...08x/index.html

looks like it might be possible from the user guide.

I got the inspiration to build it from :

http://www.tomshardware.co.uk/cheap-...view-1773.html

so my RAID is hardware controlled, not software, thus giving me some OS independence.

I bought the RAID card and extra RAM off ebay.

I bought 2 different 500Gb hard discs - so they won't have the same failure points.

and threw it all into an old scrap 900Mhz PIII Dell, running FreeNAS off the original hard disc.

I don't think you can. You're running a software RAID 1 right?

You could convert it to RAID 5 by doing a backup. Then create a new array as RAID 5 with addition of another 500GB disk and restore the data.

But as always...the FreeNAS forums would be the best place to ask.

Your problem is that the disks are mirrored and therfore you will need two 1TB disks in order to extend the array with a backup, rebuild, restore job in order to get the array extended.

You'll have to google, but I dont think most home RAID setups allow you to extend a RAID array in this way. Commercial ones do.

Google though, you might be lucky.

Could I replace one of the 500Gb discs with a 1TB disc, and rebuild the array - then wipe the removed 500gb disc and get in back in the array as an extension of the original 500gb disc, therefore giving me a 1Tb array

I.e., can it handle:

[500Gb physical + 500Gb physical controlled as one 1Tb logical drive] <-- RAID1 --> [a physical 1Tb drive as a 1Tb logical drive]

FreeNAS using GEOM and GEOM can use virtualised (as opposed to physical) drives so it ought to be possible.

How about getting 2 x 1Tb drive and having RAID1 on:

[500Gb physical + 1Tb physical controlled as one 1.5Tb logical drive] <-- RAID1 --> [500Gb physical + 1Tb physical controlled as one 1.5Tb logical drive]

and then not having to worry?
