Hey Igor, Thanks for the validation, I was also able to validate this in testing on the weekend myself, though on a db I messed up myself, and it was able to be restored. If this ends up being the solution for the customer in this case, I will follow up here if anyone is curious. Thanks again Igor, it was your post on here mentioning this a few weeks ago that actually let me know to even check this stuff. Regards, Bailey

Hi Bailey,
yes, this should be doable using the following steps:
1. Copy the very first block 0~4096 from a different OSD to that non-working one.
2. Use ceph-bluestore-tool's set-label-key command to modify "osd_uud" at target OSD
3. Adjust "size" field at target OSD if DB volume size at target OSD is different.
Hope this helps.
Thanks,
Igor

Where this was mentioned this was with an OSD in mind, would the same logic apply if we were working with a db device instead? This is assuming the only issue with the db is the corrupted label, and there is no other issues.

Bailey
