NAME¶
wwlivesync - Synchronize nodes.
SYNOPSIS¶
wwlivesync [options] nodes
DESCRIPTION¶
The live sync command will spawn rsync commands to update the running node operating system (VNFS) live. This command should only be used for minor VNFS updates, as large updates including library load could potentially break binary compatibility.
OPTIONS¶
wwlivesync options:
-l, --lookup
Identify nodes by specified property (default:
"name").
-f, --files
Pass a list of files to sync instead of the entire
VNFS.
--show
Just print what it would do instead of actually do
it.
--logdir
Directory of per-node logs (/var/log/wwlivesync).
--verbose
Increase verbosity level.
--quiet
Decrease verbosity level.
--debug
Print debugging messages.
-h, --help
Display usage summary.
TARGETS¶
The target(s) specify which node(s) will be affected by the chosen action(s). By default, node(s) will be identified by their name(s). Use the --lookup option to specify another property (e.g., "hwaddr" or "groups").
All targets can be bracket expanded as follows:
n00[0-99] All nodes from n0000 through n0099 (inclusive)
n00[00,10-99] n0000 and all nodes from n0010 through n0099
EXAMPLES¶
# wwlivesync n00[00-19] # wwlivesync --ipaddr 10.0.1.10 --netmask 255.255.0.0 --vnfs=sl6.vnfs
--bootstrap=`uname -r` n0000 n0001 # wwsh node new DEFAULT --groups=grp1,test # wwsh provision node DEFAULT --vnfs=sl6.vnfs --bootstrap=`uname -r` # wwlivesync --ipaddr 10.0.1.100 --netmask 255.255.0.0 n00[02-19]
