I’m in the process of upgrading the disks on my 4-bay Drobo v2 as I’m low on free space.
I had 4 x WD10EADS-00L5B1 installed and bought two WD20EARS-00MVWB0 drives to swap in.
I’ve found that the rebuild process is taking a very long time (yep, I realise the drives I’ve bought won’t help matters but bare with me).
When I disconnect the drobo from my computer, the drobo seems to be idle but not quite idle enough to spin down the drives. The drives chatter but not like a very intensive process is accessing them as I assume a rebuild would.
When I connect the drobo to the computer (i.e. boot up in the mornings) the rebuild hours have barely changed, maybe an hour or two less than when I left it the night before.
So having read a few forum posts here I thought ‘better safe than sorry’ and proceeded to copy everything off to a DroboFS in case I got into a rebuild loop or a power cut occured or I got bored enough to do a full reset of the drobo.
But, as the copy is proceeding, I’ve noticed the approximate hours remaining has come down significantly (i.e 84 hours down to 60 down to 42 as it currently stands).
So my question is, if I touch all the data in my disk pack i.e. read every byte of every file, will this force my drobo into rebuilding that data there and then or am I still going to have to wait a seriously long time for those green and orange LEDs to stop flashing at me?
