I built a new cluster from scratch, everything works fine. Could anyone help to find out what is stuck here? Another issue, devices don't show up after adding a host, could be the same cause. Any details about the workflow would be helpful too, like how mon gets devices when a host is added, is it pushed by something (mgr?) or pulled by mon? Thanks!

Are you running zap on the lvm volume, or the underlying block device? If you are running it against the lvm volume, it sounds like you need to run it against the block device so it wipes the lvm volumes as well. (Disclaimer: I don't run Ceph in this configuration) On Wed, Feb 10, 2021 at 10:24 AM Philip Brown <pbrown(a)medata.com> wrote: -- This e-mail and all information in, attached to, or linked via this e-mail (together the ‘e-mail’) is confidential and may be legally privileged.

I had something similar a while ago, can't remember how I solved it sorry, but it is not a lvm bug. Also posted it here. To bad this is still not fixed.
