PIMU400013 update introduces two values which allow to customize time how often Parallels Infrastructure Manager (PIM) checks slave nodes availability:1. The slave_ping_update_timeout option defines timeout of pings between from master to slave;
2. The slave_ping_wait_timeout option defines how long master node waits response for ping request. Status of pinged slave node is set to offline If no answer gained.
The default value of slave_ping_update_timeout is 120 sec, slave_ping_wait_timeout is 20. Guarantied time of detection of a slave server disconnection is slave_ping_update_timeout + slave_ping_wait_timeout seconds, by default it is 140 sec.
1. How to change the timeouts parameters by using PMC:
By default slave_ping_update_timeout and slave_ping_wait_timeout parameters do not exist. To add them open PMC, right click on the node and choose Tasks, Manage Parallels Agent Configuration, select server_group, configuration, in the right pane add both parameters, Click Apply.
Note: vzagent service restart is not required.
2. How to change the timeouts parameters in vzagent.conf file:
2.1 Open vzagent.conf file
on Windows node - x:\vz\VZAgent\etc\vzagent.conf, where x:\ is drive where VZ folder is located,
on Linux node - /var/vzagent/etc/vzagent.conf
2.2 Add slave_ping_update_timeout and slave_ping_wait_timeout parameters:
<data>
<server_group>
<configuration >
<slave_ping_update_timeout>120</slave_ping_update_timeout>
<slave_ping_update_timeout>20</slave_ping_update_timeout>
< /configuration >
</server_group>
</data>
2.3 Save vzagent.conf file;
2.4 Restart VZAgent service by means service snap-in or this command on Windows: sc stop vzaop &sc start vzaop and that one on Linux: vzagent_ctl restart
