Hi guys,
Could someone advise on what the process should be for a graceful restart please? Is it okay to just reboot via the Dappnode console or should we pause the Validator and Beacon Chain packages first, etc?
kind regards,
AJ
I’ve been testing different ways to re-start my host PC and so far I haven’t found a way that doesn’t require the Beacon Chain to be deleted and re-synched from scratch. This is obviously a major issue if for whatever reason you need to restart the host or there’s a power outage.
I have tried pausing/exiting the Medalla Validator, Beacon Chain, Goeth chain, Geth chain and then restarting. After a restart all packages auto-start which is fine. Geth & Goeth chains re-sync OK.
The Medalla Beacon Chain logs show the following once I restart the package…

Any thoughts?
Hey @AJR
Medalla is kinda deprecated and Pyrmont testnet is the new place for testing.
If you update all DAppNode Packages to the last current version DAppNode should start all the packages for you in case of a power loss as stated in the below How-To
