[sheepdog-users] Single disk getting full

I unplugged the full disk;
waited for the recovery to be done;
(manually removed data in obj dir, just to be sure)
plugged it back and waited for the recovery:

# collie node md info
Id      Size    Used    Avail   Use%    Path
 0      2.7 TB  1.8 TB  950 GB   66%    /mnt/sheep/dsk02
 1      169 GB  76 GB   93 GB    44%    /mnt/sheep/dsk01/obj

Now it's fine :-)

I have to do the same on another node:

Node 0:
 0      166 GB  154 GB  12 GB    92%    /mnt/sheep/dsk01/obj
 1      465 GB  318 GB  147 GB   68%    /mnt/sheep/dsk02
 2      1.8 TB  1.1 TB  716 GB   61%    /mnt/sheep/dsk03

In these two cases (node 2 and node 0), it's ok to unplug the full
disk because there is enough space on the second (and third) disk to
rebuild data.
If there was not enough space, it was probably going to fail the rebuild.

I know in theory it should not happen to have a disk used more than
another but it actually does.
May it be possible to implement something like
  collie node md reweight

Thank you.
