Save fast-reboot state into the db#3741
Conversation
|
Looks generally good to me. I am wondering what is your plan of using the EX 180 information? We might want to run a test fast-reboot -> make sure it is executed as fast-reboot. Then restart swss, make sure it is a cold restart. |
|
@yxieca This is instruction to redis to remove the key in 180 seconds. |
|
I see. Interesting. Do we need this expiry? swss restart should clear the db including this key, right? |
|
@yxieca But if we restart bgpd only it will be always fast-reboot start of bgpd |
|
Good point! |

for master we are using frr, so sonic-frr init should be modified. I will let pavel fix that. |

Separate PR was created for 201811 branch due to merge conflicts. |
Put a flag for fast-reboot to the db using EXPIRE feature. Using this flag in other part of SONiC to start in Fast-reboot mode. If we reload a config, the state in the db will be removed.
Fixes sonic-net/sonic-buildimage#4006 1. save fast-reboot state into the db(aligned with sonic-net/sonic-buildimage#3741) 2. `sonic-buildimage/files/scripts/syncd.sh` could detect the FAST reboot type by the saved fast-reboot state, and request syncd to fast shutdown.
Fixes #3697
