Yes it recovered when I put the OSD back in. The issue is that it fails
to sort itself out when I remove that OSD even though I have loads of
space and 8 other OSDs in 4 different zones to choose from. The weights
are very different (some 3.2 others 0.36) and that post I found
suggested that this might cause trouble for the crush algorithm. So I
was thinking about making them more even before removing the OSD.
Sure, that sounds like a good plan. If the balancer is not able to
optimize at this point, the improved balancer bij Jonas Jelten might do
the trick here [1], also see ML thread [2].
Do you have many different pools?
What Weiwen Hu said in reply to this threads sounds very plausible. You
might dump your crush map, remove OSD.7, and check if the mappings can
still be made.
