osdeploy¶
osdeploy operating system provision process. Supports two modes - ‘Realtime monitor’ and ‘Replay history’.
Realtime monitor: This is a default. This tool with monitor provision state of the node. Trigger ‘Realtime monitor’ before rebooting target node to do provisioning.
Replay history: Used after provisioning is finished to probe the previously completed provisioning.
Note: Currently, hierarchical structure is not supported.
Usage¶
xcatprobe osdeploy -h
xcatprobe osdeploy -n <node_range> [-t <max_waiting_time>] [-V]
xcatprobe osdeploy -n <node_range> -r <xxhxxm> [-V]
Options:
- -n: The range of nodes to be monitored or replayed.
- -r: Trigger ‘Replay history’ mode. Follow the duration of rolling back. Units are ‘h’ (hour) or ‘m’ (minute). If unit is not specified, hour will be used by default.
- -t: The maximum time to wait when doing monitor, unit is minutes. default is 60.
- -V: Output more information.
-r means replay history of OS provision, if no -r means to do realtime monitor.
Realtime monitor¶
To monitor OS provisioning in real time, open at least 2 terminal windows. One to run osdeploy probe:
xcatprobe osdeploy -n cn1 [-V]
After some pre-checks, the probe will wait for provisioning information, similar to output below:
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]
-------------------------------------------------------------
Start capturing every message during OS provision process......
-------------------------------------------------------------
Open second terminal window to run provisioning:
nodeset cn1 osimage=<osimage>
rpower cn1 boot
When all the nodes complete provisioning, the probe will exit and display output similar to:
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]

All nodes specified to monitor, have finished OS provision process [ OK ]
==================osdeploy_probe_report=================
All nodes provisioned successfully [ OK ]
If there is something wrong when provisioning, this probe will exit when timeout is reached or Ctrl+C is pressed by user. The maximum time can be set by using -t as below(default 30 minutes)
xcatprobe osdeploy -n cn1 -t 30
Replay history¶
To replay history of OS provision from 1 hour 20 minutes ago, use command as
xcatprobe osdeploy -n cn1 -r 1h20m
Output will be similar to:
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]
Start to scan logs which are later than *********, waiting for a while.............
