I get this now with my MN:
Warning: Your masternode version (120100) is behind the official version (120102). This is from DASHcentral.
I am running 12.1 so do I need to upgrade again. I just updated last week...??
and go through the update procedure and reset my time and loose rewards etc.
I don't run any on dashcentral. Do you run your remote node (vps) there? It should be taken care of by them. You don't have to start-alias your mn from local. It's simple update and you won't lose your rewards.
No, I run my own on a VPS, I just use Dashcentral to monitor the MN. So, is it just a matter of replacing the dashd on the server? what about sentinel?
Sentinel needs to be updated as well, for those not using Dashman you can use following command : cd .dashcore/sentinel && git pull
cronjob for Sentinel needs to be set to 1 minute, you can use the following cron :
* * * * * cd /home/YOURUSERNAME/.dashcore/sentinel && ./venv/bin/python bin/sentinel.py >/dev/null 2>&1
Warning : there is currently some discussion going on if sentinel is placed inside the .dashcore folder (atlassian guide) or directly in your home folder (github guide).
This could effect both your cronjob and the sentinel update itself. To be continued ...
