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
do not daemonize after startup (run in foreground), but log to the usual location. Useful when run via crun(8).
--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).

AVAILABILITY
