Subject: ceph_manager: test offline split via ceph-objectstore-tool
X-Git-Tag: v10.2.6~165^2^2~35^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=a199dcd9828247be9ddc9efbc40deb3b5c926ba2;p=ceph.git

ceph_manager: test offline split via ceph-objectstore-tool

When killing an osd, split all pools with a low threshold.
This will slow down tests, but should not impact correctness.
