3 disk RAID 5 array shows 1/2 capacity

12340987 · 08-15-2007, 05:39 AM

I have 2 250GB Western Digital and 1 Seagate 250GB drive. I just added the SG and only see 250GB when I know I should see 500. Does the fact that they are of different brands make a difference? After migrating, a dialog box even came up telling me to restart so I could see the increased storage and I did to no avail.
I have an intel ICH8R southbridge and the software says the array is healthy with 3 drives and is in mode 5, I don't know where the 250GB went.

Anyone need a couple HDDs?

How did you have it setup before you put the 3rd disk in? Just adding a drive wont make the storage instantly available to use, you have to partition and format it.

it was a raid 1 array and i migrated to raid 5 after the addition of the 3rd

migration does not always work, sometimes you gotta build from ground up. back up your data then rebuild the RAID from scratch
