Hi,

it should work with ceph-volume after you re-created the OS:

ceph-volume lvm activate --all

We had that case just recently in a Nautilus Cluster and it worked perfectly.

Zitat von Daniel Da Cunha <dan...@ddc.im>:

Hello,
As a hobbies, I have been using Ceph Nautilus as a single server with 8 OSDs. Part of the setup I set the crush map to fail at OSD level: step chooseleaf firstn 0 type osd.

Sadly, I didn’t take the necessary precaution for my boot disk and the OS failed. I have backups of /etc/ceph/ but I am not able to recover the OS.

Can you think of a way for me to recreate the OS and adopt the 8 OSD without loosing the data?

Thanks & regards,
Daniel
