Rebalance can cause a FID to be over-replicated if a device is left in DRAIN mode #68

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 

if a device is in drain mode without rebalance running, and a fid with a  copy 
on it has a replication event, replication may over replicate and  leave the 
fid.

On the PBworks production system, we ended up with 2.3TB of over-replicated 
fids, that required the reconfiguration of the tracker to fix, and a multi-day 
FSCK.
