We have a scenario when nodes lost contact for 10 seconds and rejoined, some
service units ended up in Terminating state.
For example, the following message was seen from /var/log/messages:
NO Lost contact with 'appbox'
We saw some service units on the same box disabled. Then we performed lock and
lock-in on the disabled service unit:
amf-adm lock safSu=amfSU2.1,safSg=amfSG2,safApp=myApp
amf-adm lock-in safSu=amfSU2.1,safSg=amfSG2,safApp=myApp
Then we tried the following commands:
amf-adm repaired safSu=amfSU2.1,safSg=amfSG2,safApp=myApp
amf-adm unlock-in safSu=amfSU2.1,safSg=amfSG2,safApp=myApp
For either repaired or unlock-in, we got the following error:
error - command timed out (alarm)
SU state stayed as:
safSu=amfSU2.1,safSg=amfSG2,safApp=myApp
saAmfSUAdminState=LOCKED-INSTANTIATION(3)
saAmfSUOperState=ENABLED(1)
saAmfSUPresenceState=TERMINATING(4)
saAmfSUReadinessState=OUT-OF-SERVICE(1)
Eventually we had to stop the node and restart the node to bring things back to
normal.
Why disabled service unit stuck at TERMINATING state? What made a service unit
stuck at TERMINATING state?
If a node is lost for a little while, what are the effects of the node lost
contact in the cluster?
How to repair the damage caused by the node lost?
Thanks!
