Hello list,
is there a possibility to disable / skip the jornal? Stuff like
FlashCache, BCache and others seem to work much better but sequential
I/O becomes a bottleneck if the ceph journal is on a single ssd.
Greets,
Stefan

As far as I know, the journal is a required element for consistency.
Sequential I/O is a benefit of the journal.
