NAME
cosd − ceph object storage daemon
SYNOPSIS
cosd −i osdnum [ −−osd−data datapath ] [ −−osd−journal journal ] [ −−mkfs ]
DESCRIPTION
cosd is the object storage daemon for the Ceph distributed file system. It is responsible for storing objects on a local file system and providing access to them over the network.
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).
OPTIONS
|
−D |
Debug mode: do not daemonize after startup (run in foreground) and send log output to stdout. | ||

−f |

−−osd−data osddata
Use object store at osddata.
−−osd−journal journal
Journal updates to journal.
|
−−mkfs |
Create an empty object repository. Normally invoked by mkcephfs(8). |
−c ceph.conf, −−conf=ceph.conf
Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf for runtime configuration options.
−m monaddress[:port]
Connect to specified monitor (instead of looking through ceph.conf).
