It is responsible for storing objects on a local file system +and providing access to them over the network. +.sp +The datapath argument should be a directory on a btrfs file system +where the object data resides. The journal is optional, and is only +useful performance\-wise when it resides on a different disk than +datapath with low latency (ideally, an NVRAM device). +.SH OPTIONS +.INDENT 0.0 +.TP +.B \-f, \-\-foreground +Foreground: do not daemonize after startup (run in foreground). Do +not generate a pid file. Useful when run via \fBcrun\fP(8). +.UNINDENT +.INDENT 0.0 +.TP +.B \-d +Debug mode: like \fB\-f\fP, but also send all log output to stderr. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-osd\-data osddata +Use object store at \fIosddata\fP. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-osd\-journal journal +Journal updates to \fIjournal\fP. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-mkfs +Create an empty object repository. Normally invoked by +\fBmkcephfs\fP(8). This also initializes the journal +(if one is defined). +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-mkkey +Generate a new secret key. This is normally used in combination +with \fB\-\-mkfs\fP as it is more convenient than generating a key by +hand with \fBcauthtool\fP(8). +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-mkjournal +Create a new journal file to match an existing object repository. +This is useful if the journal device or file is wiped out due to a +disk or file system failure. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-flush\-journal +Flush the journal to permanent store. This runs in the foreground +so you know when it\(aqs completed. This can be useful if you want to +resize the journal or need to otherwise destroy it: this guarantees +you won\(aqt lose data. +.UNINDENT +.INDENT 0.0 +.TP +.B \-c ceph.conf, \-\-conf=ceph.conf +Use \fIceph.conf\fP configuration file instead of the default +\fB/etc/ceph/ceph.conf\fP for runtime configuration options. +.UNINDENT +.INDENT 0.0 +.TP +.B \-m monaddress[:port] +Connect to specified monitor (instead of looking through +\fBceph.conf\fP). +.UNINDENT +.SH AVAILABILITY +.sp +\fBcosd\fP is part of the Ceph distributed file system.
