[sheepdog-users] cluster-full due to different size devices

[Valerio Pachera]

It's happening again:
The node sheepdog002 is filling up it's smaller device (500G 87%
/mnt/wd_WMAYP1690412).
The same is not happening to node sheepdog004 (500G) , nor sheepdog003 (217G).

Note: i killed sheepdog002 and insert it back to the cluster right away.
This triggered the cluster recovery.
When I noticed sheepdog002 was filling up its smaller disk, I tried to
call cluster reweigh, but it didn't help.

Now I'm going to unplug  /mnt/wd_WMAYP1690412 but I fear other "small"
devices are going to fill up.

I can't follow the recovery because it's pretty late here now : /
