# connect to and mount an existing volume
cosmic connect global-name /dev/mdX
mount /dev/mdX /var/mdX
# unmount and disconnect volume
umount /var/mdX
cosmic disconnect global-name /dev/mdX
# destroy a volume (should be run when disconnected)
cosmic destroy global-name
# add a new target to RAID array
cosmic add global-name /dev/mdX 10G 10.0.0.3
# remove a target from RAID array
cosmic remove global-name /dev/mdX 10.0.0.3
# display status of a connected volume (as colon-separated values)
cosmic status global-name /dev/mdX
# to create a new volume without connecting
cosmic create global-name - 10G 10.0.0.1 10.0.0.2
# to connect to an uninitialized array and to init it
cosmic connect --initialize global-name /dev/mdX
mkfs t ext3 /dev/mdX
