[Gluster-devel] bit rot

[Raghavendra Bhat]

Hi,

As per the design dicussion it was mentioned that, there will be one 
BitD running per node which will take care of all the bricks of all the 
volumes running on that node. But, here once thing that becomes 
important is doing graph changes for the BitD process upon 
enabling/disabling of bit-rot functionality for the volumes. With more 
and more graph changes, there is more chance of BitD running out of 
memory (as of now the older graphs in glusterfs are not cleaned up).

So for now it will be better to have one BitD per volume per node. In 
this case, there will not be graph changes in BitD. It will be started 
for a volume upon enabling bit-rot functionality for that volume and 
will be brought down when bit-rot is disabled for a volume.
