What is the best way to change hard drives to larger hard drives on a server RAID
Posted on 2013-11-08
I have an SBS 2008 server. It has two RAIDs. A RAID 1 for the OS and a RAID 5 for all of the data. The RAID 1 has two 80GB drives and the RAID 5 has a ton of space and is not the issue.
I have two WD Enterprise Storage 250 GB drives. My question is what is the best way to swap them. I should say, I am quickly running out of space.
1. Remove one of the drives and insert one of the new drives and let it rebuild, then remove the other small drive and insert the other large drives and let it rebuild.
2. Make a backup of the RAID 1. Remove both of the 80GB drives. Put in both of the 250GB drives, then restore. I believe I would have to resize the information on the drive.
Dumb question: I know that with a RAID 1, you can afford to have one drive crash as long as the other is fine. If it crashes, then you would lose all your data. My confusion is, if I remove both drives, but they are still good drives, is the data still intact on both drives. Therefore, if everything didn't work when I tried the 250GB drives, could I just put them back in. Or would they be a drive issue?
Thanks for your help.
