Thanks a lot, that helped.
Should have cleaned leftovers before :)

pgs.
state on remapped pgs like:
{ "state": "active+remapped",
"epoch": 9420,
"up": [
9],
"acting": [
9,
5],
Any help/hints how to trigger those stuck pgs to up state on 2 osds?

Hope something can be done still, or I will have to move several TB

Anyway, it does not feel like the problem cause is clear. May be I

Just wondering would OSD work on ocfs2 and what would performance

Any thoughts/experience?
