Crazy slow rebuild speed


Recommended Posts

Swapping out a new 12TB in place of an existing 3tb, the rebuild process is sitting at a consistent 6mb/s. I stopped all my dockers/VMs.  Doesn't make a difference.  I changed the cables and the controller its attached to.  No change.  I ran drive speed tests (from the docker) while the rebuild was stopped and no issues with speed from any drives or controller tests.  CPU usage is minimal.  I'm unsure what else to check to make this thing speed up.

 

Any help to get this sped up would be appreciated as I don't really want to wait 25 days for a rebuild.

I let it sit for about 20 mins and it randomly went up to regular speed.  Unsure why it took so long to get up to speed.  Just in case anyone else comes across this. 

 

I also ran a parity check and it took the same delay to start getting good speed.
