Hi!
After upgrading MONs and MGRs successfully, the first OSD host I upgraded on Ubuntu Bionic
from 14.2.16 to 15.2.10
shredded all OSDs on it by corrupting RocksDB, and they now refuse to boot.
RocksDB complains "Corruption: unknown WriteBatch tag".
The initial crash/corruption occured when the automatic fsck was ran, and when it
committed the changes for a lot of "zombie spanning blobs".
Tracker issue with logs:
https://tracker.ceph.com/issues/50017
Anyone else encountered this error? I've "suspended" the upgrade for now :)
