Hi Dave and everyone else affected,
I'm responding to a thread you opened on an issue with lvm OSD creation:
https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/YYH3VANVV22…
https://tracker.ceph.com/issues/43868
Most important question: is there a workaround?
My observations: I'm running into the exact same issue on mimic 13.2.10. The strange
thing is, that some OSDs get created and others fail. I can't see a pattern here. I
have 1 host where every create worked out and another where half failed. The important
lines in the log are probably:
stderr: 2021-02-06 13:48:27.477 7f46756b4b80 -1

I really need to get a decent number of disks up very soon. Any help is appreciated. I can
provide more output if that helps.
Best regards and good weekend!
