Thread: All u storage experts plz help! How to move my system to a new RAID array

hi guys,

have following problem. bought second ssd computer , i'm planning raid-0 array using motherboard's built-in raid adapter.
on hard drive have windows system , other partitions apart ubuntu. now, i'm not storage expert if use dd bit-by-bit image of current state of system , add 2nd disk, create array can dd image (and expand file systems etc)?

if simple upgrade , copying on again single hard disk know work. however, work raid array? that's i'm asking because know have different cluster sizes, raid stripes etc.. ?

think?!

i guess thought since had dd image had nothing lose in trying different scenarios , figuring out work.
right , soft/fakeraid. however, since i'm using 2 ssd drives in laptop (sony vaio z) hoping wont experiencing hw failures , it's core i7 system resources not issue either. also, wanted fakeraid on linux raid due fact i'm dual booting windows 7.

started creating fakeraid array in bios, booting linux in live cd , restoring dd image onto fakeraid device. surprise, worked right away. windows 7 booted no problems. however, performance suffering due fact 128kb stripe size introduced misalignment partitions. googled bit , unable find solution didn't include re installing everything.

in end (and unfortunately) had realign partitions filesystem , raid array , ssd block size. used online calculator check ok. went gpt partition table , have no problems grub2.
far i've reinstalled main os (linux) , performance noticeably faster. haven't been able re install windows yet check if that's true there also.

again, thank reply.

hope else finds useful!
