pstorage-make-cs − create a new CS for a Pstorage cluster
pstorage make−cs −r path [−a address] [−b address1[:port1][,address2...]] [−u user] [−x] [−j path] [−s dsize[:msize] ] [−S] [−t tier]
pstorage−make−cs(1) creates a new CS repository directory and, optionally, adds it to a cluster’s auto−startup list on the current host. The −b option can be used to specify IP addresses of already active MDSs in the cluster if autodiscovery by a cluster name does not work.
Note that for a cluster to be operational, a sufficient number of CSs (equal or more than the replication factor that is set to 1 by default) must be running. Use pstorage top to look for running CSs and pstorage set−attr −p −R / replicas=norm:min to configure the replication factor, if necessary.
−r, −−repo−dir=path
Set the path to the new CS repository directory.
−a, −−address=address
Set IP address to listen on (optional).
−b, −−bs−list=address1[:port1][,address2...]
Set the bootstrap list of MDSs if autodiscovery does not work (optional).
−x, −−no−auto−start
Do not register the new CS in the auto−start list for pstorage−csd (optional).
−u, −−user=user
Change the owner of the created files and directories to the specified user; "pstorage" by default. Must be run as root. (optional).
−j, −−journal=path
Set path to directory with CS’s write journal (optional).
−s, −−journal−size=dsize[:msize]
Set size for CS’s journal, where: dsize − maximum size of data stored in journal in megabytes, will be rounded up to multiple 64 Mb and msize is maximum size of metadata stored in journal (optional). See pstorage−ssd(7) for the journal discussion.
−S, −−no−checksums
Disable checksumming for journal transactions (optional).
−t, −−tier=tier
Set storage tier for new CS repository. The value of tier must be in range 0−3.
