The \fIjournal\fP is optional, +and is only useful performance-wise when it resides on a different +disk than \fIdatapath\fP with low latency (ideally, an NVRAM device). +.SH OPTIONS +.TP +\fB\-D\fP +Debug mode: do not daemonize after startup (run in foreground) and send log output +to stdout. +.TP +\fB\-f\fP +do not daemonize after startup (run in foreground), but log to the usual location. +Useful when run via +.BR crun (8). +.TP +\fB\-\-osd\-data \fIosddata\fP +Use object store at \fIosddata\fP. +.TP +\fB\-\-osd\-journal \fIjournal\fP +Journal updates to \fIjournal\fP. +.TP +\fB\-\-mkfs\fP +Create an empty object repository.
