raid migration partition problems

[dowxp]

i have .. say 8x500, and i've now added 6 drives in and migrated the array up. now the array is bigger, and in the manager, i see the original GPT partition, and an unformatted one. how do i add them both without losing data on the original partition? Thanks

Your RAID controller or the management software usually would be used to tell it to rebuild the array, by parting the data out to include the new drives, assuming you are using something other than RAID0, I believe. The manual for the controller should tell you.

If you're using Windows RAID, there's got to be instructions on MS's site.

hm, the raid function- i can migrate fine. it is just windows' partition that is the problem.

Thats the problem with understanding raid..

You expanded the RAID container size.. many controller can not expand the windows primary/active partition.. which case you need to use something like parition magic..

but before using such tool, you should back up as there are numerous nightmares..

What I done in the past was ghost the entire array out, add and expand the raid container.. ghost back the image to the full partition..

with your array size 8x500.. that be pretty hard..

You cannot extend the partition if the system page file is located on the partition. Move the page file to a partition that you do not wish to extend.

i wouldn't really trust this with my life... so you still need to backup before extending

yes, i have found that as well. i wonder if it can be used on GPT volumes.
