my drobo was set up as 2+2+2+1. i bought a new 2TB and swapped it in, resulting in 2+2+2+1. i went away for a long weekend, thinking the rebuild would be done when i got back because the previous two times i had swapped a 1TB drive for a 2TB drive it had taken a few days each time.
it has been almost 3 weeks, and the drobo is still rebuilding. drobo dashboardgives me estimates in the 3,000 to 4,000 hour range. recently i’ve become worried that it would never complete and tried to copy the data off of it, but the access speed is so slow when reading from the drobo that it would take thousands of hours as well. also, the drobo dashboard keeps losing and re-establishing its connection to the drobo.
i suspect that the new drive is bad. sometimes when the drobo restarts (i’ve tried following instructions like those at http://support.datarobotics.com/app/answers/detail/a_id/167/session/L3NpZC9QRGpHYURVag%3D%3D/kw/excessive/r_id/100004/sno/1) the drive bay that was recently swapped indicates solid red and the other three bays indicate solid green. however, it usually goes into a rebuild shortly after this with all 4 lights blinking green and orange.
my question is… can i remove the newly swapped-in drive and replace it with the drive that i took out? the drive i removed hasn’t been touched so it would still have its original data.
