Just to follow up...
I was able to use a per-osd device copy to migrate nearly 80 FileStore
osds to BlueStore using a version of the script in:

Hi,
The docs have scant detail on doing a migration to bluestore using a
per-osd device copy:
https://docs.ceph.com/en/latest/rados/operations/bluestore-migration/#per-osd-device-copy
This mentions "using the copy function of ceph-objectstore-tool", but
ceph-objectstore-tool doesn't have a copy function (all the way from
v9 to current).
Has anyone actually tried doing this?
Is there any further detail available on what is involved, e.g. a
broad outline of the steps?
Of course, detailed instructions would be even better, even if
accompanied by "here be dragons!" warnings.
Cheers,
Chris
