usage:
node ls [-s] [-b|--brief] [-m|-l|--sys|--io|--fsck] [<node>] : list all nodes or only <node>. <node> is a substring match and can be a comma seperated list
-s : silent mode
-b : display host names without domain names
-m : monitoring key=value output format
-l : long output - list also file systems after each node
--io : print IO statistics
--sys : print SYS statistics (memory + threads)
--fsck : print filesystem check statistcis
node config <host:port> <key>=<value : configure file system parameters for each filesystem of this node
<key> : gw.rate=<mb/s> - set the transfer speed per gateway transfer
<key> : gw.ntx=<#> - set the number of concurrent transfers for a gateway node
<key> : error.simulation=io_read|io_write|xs_read|xs_write|fmd_open
If offset is given the the error will get triggered for request past the given value.
Accepted format for offset: 8B, 10M, 20G etc.
io_read[_<offset>] : simulate read errors
io_write[_<offset>] : simulate write errors
xs_read : simulate checksum errors when reading a file
xs_write : simulate checksum errors when writing a file
fmd_open : simulate a file metadata mismatch when opening a file
<none> : disable error simulation (every value than the previous ones are fine!)
<key> : publish.interval=<sec> - set the filesystem state publication interval to <sec> seconds
<key> : debug.level=<level> - set the node into debug level <level> [default=notice] -> see debug --help for available levels
<key> : for other keys see help of 'fs config' for details
node set <queue-name>|<host:port> on|off : activate/deactivate node
node rm <queue-name>|<host:port> : remove a node
node register <host:port|*> <path2register> <space2register> [--force] [--root] : register filesystems on node <host:port>
<path2register> is used as match for the filesystems to register e.g. /data matches filesystems /data01 /data02 etc. ... /data/ registers all subdirectories in /data/
<space2register> is formed as <space>:<n> where <space> is the space name and <n> must be equal to the number of filesystems which are matched by <path2register> e.g. data:4 or spare:22 ...
--force : removes any existing filesystem label and re-registers
--root : allows to register paths on the root partition
node txgw <queue-name>|<host:port> <on|off> : enable (on) or disable (off) node as a transfer gateway
node proxygroupadd <group-name> <queue-name>|<host:port> : add a node to a proxy group
node proxygrouprm <group-name> <queue-name>|<host:port> : rm a node from a proxy group
node proxygroupclear <queue-name>|<host:port> : clear the list of groups a node belongs to
node status <queue-name>|<host:port> : print's all defined variables for a node
