Is this RAID 5 array too risky to expand?

post #1 of 6
Thread Starter 
12 x 2tb RAID 5
-about 4-5 yrs old
-just finished rebuilding after disk6 dropped out after troubleshooting a looping BSOD
-disk3 reports 37 bad sectors
-disk7 reports 3 bad sectors

I just picked up another (2) 2tb drives. I added one as a hot spare and wanted to expand the volume with the other. I'm just concerned the array might not survive the expansion because an array of this size will probably take more than a week to finish. I have no backup and it would really suck to lose all the data but it won't be the end of the world if I do.

If data is not important then i would just add the drives and see how it goes. Anyways considering the explanation you just gave running those 5 years old drives is very risky in its own sense smile.gif i generally replace drives every 4 years to be on safer side.

I went ahead and started the expansion on Sun and when I last checked on Wed it was at 61%. During this time I was able to access all the data and see the volume just fine. I checked again last night and the percentage seem like it restarted because it was at 17%. The volume is not visible in Explorer anymore but still shows in Disk Management. I suspect it may have restarted after Windows updates because I forgot to set it not to install them until I do so. I will have to check the events to see if this is what happened.

Now I'm worried that the restart screwed up the expansion and wiped the data.

You were rebuilding from inside Windows? Is it a software RAID?

Either way, I would recommend replacing the drives with bad sectors. They are bound to die eventually.

Yes, in Windows 7 Pro x64. It was a pretty new install so there were probably updates that were needed and required a restart. This is with a Highpoint RocketRaid card. On the last raid rebuilt I had to restart it a few times and it always picked up where it left off.

Yep, just as I thought. Windows updates forced a restart and caused the expansion to restart as well. In the process it somehow corrupted or overwrote the GPT partition table. Disk management shows the volume as RAW and the additional 4TB. I haven't extended the volume yet in hopes of trying recovery software to see whatever I can get back.
