SYNOPSIS

sxadm cluster [\,OPTIONS\/] <MODE> \,[NODE1 [NODE2...]] sx://\/[\,profile@\/]\,cluster\/

where NODE is a string in the form <CAPACITY>/<ADDRESS>[/INTERNAL_ADDRESS][/UUID], describing a node in a cluster (used for options, which operate on a list of nodes).

DESCRIPTION

sxadm cluster is used to create and maintain remote clusters. In contrast to sxadm node, all operations are performed over the network, therefore it requires a valid admin access to the cluster.

OPTIONS

-h, --help Print help and exit
--full-help
  Print help, including hidden options, and exit
-V, --version
  Print version and exit

    Operation modes:

-N, --new Create a new SX cluster with a local node. This command is only used when creating the cluster and requires specification of the first node joining the cluster. If a UUID is not provided in the NODE’s string, it will be automatically assigned. The subsequent nodes get joined to the cluster with --modify.
-I, --info Shows configuration of the cluster, its list of nodes and current operations.
-M, --modify
  Modify an existing SX cluster. This option allows adding, removing and resizing nodes. It operates on a list of nodes - the current list can be obtained with --info.
-s, --status
  Show current status of all nodes. This includes disk usage, memory usage, software version, and others.
-L, --lock This option applies an advisory lock and should be performed before making changes to the cluster.
-U, --unlock
  This option removes an advisory lock.
-R, --resize=<+/->SIZE
  This option can proportionally grow or shrink the entire cluster, resizing each individual node with respect to its size. For example, growing a cluster made of three nodes: A(1TB), B(1TB), C(2TB) by 4TB will results in new node sizes: A(2TB), B(2TB), C(4TB). The benefit of using this option is a minimized relocation of data across the cluster. The nodes can be also resized individually with --modify.
-F, --replace-faulty
  Replace faulty nodes in a cluster. This option takes pairs of faulty node - replacement node, where the replacement node should provide the same capacity as the faulty one. The replace process assumes all data on the faulty node has been lost and will attempt to recover it from the other nodes in the cluster.
-S, --set-faulty
  This option marks selected nodes as faulty, which will no longer be used by the clients. They can be later replaced with --replace-faulty.
-G, --force-gc
  Force a garbage collection cycle on all nodes.
-X, --force-expire
  Force GC and expiration of reservations on all nodes.
--get-cluster-key
  Obtain remote cluster key.
-m, --set-mode=\,MODE\/
  Set cluster operating mode (’ro’ or ’rw’ for read-only or write-only respectively). The read-only mode can be used to perform cluster maintainance (eg. perform sxadm node --check).
--upgrade
  Perform sanity checks on all nodes in the cluster. Start a cluster upgrade if no problems are found, followed by a garbage collection.
--set-meta=\,"KEY=VALUE"\/
  Set cluster metadata in a form of a key-value pair. The metadata can only be set by a cluster administrator, but can be obtained by all users.
--get-meta=\,KEY\/
  Display a specific entry from the cluster metadata. When the key is ALL, then all entries will get displayed.
--delete-meta=\,KEY\/
  Delete a specific entry from the cluster metadata.

    New cluster options:

-d, --node-dir=\,PATH\/
  Path to the node directory.
--port=\,INT\/
  Set the cluster destination TCP port (default 443 in secure mode or 80 in insecure mode).
--ssl-ca-file=\,PATH\/
  SSL CA certificate file of the SX cluster (same file as in httpd configuration).
-k, --admin-key=\,PATH\/
  File containing a pre-generated admin authentication token or stdin if "-" is given (default autogenerate token).

    Common options:

-b, --batch-mode
  Turn off interactive confirmations and assume yes for all questions.
-H, --human-readable
  Print human readable sizes (default=off)
-D, --debug
  Enable debug messages (default=off)
-c, --config-dir=\,PATH\/
  Path to SX configuration directory

    Cluster locking options:

--locking-node=\,ADDRESS\/
  IP address of a node used to aqcuire a cluster lock. By default a random node will be selected and the lock will be spread across the cluster.
