So you mean that you still have inactive PGs although your OSDs are
all up? In that case try to 'ceph pg repeer <PG_ID>' to activate the
PGs, maybe your RGWs will start then.

That means if one host goes down you can't recover until the node is
back, you should have at least one or two more nodes so you have at
least some recovery options.

Did you check the MON and/or MGR logs? Do the MONs mark the OSDs down
after 10 minutes (or was it 15?)? That sounds a bit like flapping
OSDs, you might want to check the mailing list archives for that,
setting 'ceph osd set nodown' might help during the migration. But are
the OSDs fully saturated ('iostat -xmt /dev/sd* 1')? If updating helps
just stay on that version and maybe report a tracker issue with your
findings.
