mds: stopping MDS with subtrees pinnned cannot finish stopping
Added by Patrick Donnelly over 5 years ago.
Updated almost 4 years ago.
Backport:
octopus,nautilus
Description
Apparently due to checks that prevent export of pinned directories.
This should be reproducible with:
ceph fs set max_mds cephfs 2
mkdir -p foo/bar
setfattr -n ceph.dir.pin -v 1 foo
ceph fs set max_mds cephfs 1
ceph status # should show rank 1 stuck in up:stopping
Actually, this just seems to be really slow when there are lots of subtrees (and large cache without outstanding caps) that are pinned. Zheng, any idea why this would be slow?

I believe this is fixed already but needs double-checked. It may also be fixed by the ephemeral pinning branch for #41302.

Yeah, I have tried for hours and couldn't reproduce it now with the latest upstream code.

Thanks for checking Xiubo. I'll mark this closed.
