I'm getting the same trouble with creating the ceph monitor. Latest debian stretch, latest pve updates, three older machines running smoothly except the mentioned RocksDB-error.
CPUs:
Core 2 Quad Q6600 @ 2.4 GHz
Core 2 Duo E6550 @ 2.33 GHz
Core 2 Duo E6750 @ 2.66 GHz
I've exchanged the Core2Quad with a Xeon 3050 @ 2.13 GHz, but it didn't work either.
This information, logs and command lines are already uploaded to the bugtracker.
Later this weekend I will try to use other machines with a not-so-old Core i7 and maybe an AMD FX 8950 too.
