Hi Jimmy, I should still have all the logs.
What I did is pretty simple. I tried to turn the cluster off while a single regioned 250GB table was under major_compaction to get splitted. I will targz all the logs for the few last days and make that available. On the other side, I'm still not able to bring it back up...
