my Drobo was operating with 1TB/1TB/1TB/500GB for months now and it’s filled with 1.6TB data.
Today I wanted to replace the 500GB drive with another 1TB drive.
I pulled the 500GB drive and its LED turned to RED. Drobo Dashboard said, Drobo can no longer protect my Data from any drive failure (red box) and additionally told me, I’m almost out of protected space (yellow box).
The other three LEDs stayed green, no flashing green/yellow!
Any explanation on that? Maybe, because I only use 1.6TB, the remaining three 1TB drives already had a consistent protected raid, so no re-layout was necessary? But then, why did the Dashboard tell me my Data is no longer protected (without flashing LEDs?).
After that, I pushed the new 1TB into the fourth slot. Drobo immediately started a re-layout and is doing this for hours now (Dashboard says, it will take another 32 hours?!?).
If Drobo was in a protected state with the three 1TB drives, why the hell is it doing a 35h re-layout with the new drive inserted?
And if it wasn’t, why didn’t the LEDs flash green/yellow when I pulled the drive?
Is the unit faulty?
Drobo Gen 2, FW 1.3.5
Dashboard 1.6.8 on Windows Server 2003 (which sucks btw, “DDService” fails and has to be restarted about twice a day!)
