Question

Posted

Hello,

I currently have a four bay DAS that is populated with four 16TB drives, all four drives (G, H, I J) are in a single pool (F).  I have file duplication (2x) and balancing turned on.  My understanding is that this creates to copies of every file in the pool.  Each copy is located on a different physical drive in the pool.  So in theory, if one drive is lost for whatever reason, I've not lost any data.

In the event a single drive in the pool fails and I need to replace it, is the process more complicated than simply power down, replace the drive, power back up and let Drivepool do it's load balancing and duplication with the new drive?  Will it automatically detect the drive change and act accordingly, or will I need to manually remove the bad drive from the pool and add the new one?

Or, am I way off base and I need to do something completely different in the event of a drive failure?

Thanks!

Hi Dalmus! Yes, pretty much what you're thinking: power down, replace the drive, power back up, tell DrivePool to remove the missing bad drive and to add the new good one, it will handle the rest. If you had any drive-specific rules (e.g. file placement) you would have to update those.
