Restarted MN

[naruby]

My VPS got restarted last night because of a problem with the host.
Dashd started (tx to monit) but wasn't running as masternode.

I need to start the MN via my cold wallet, this should be the case right ?

dash.conf in hot side

#---- dashd settings
listen=1
server=1
daemon=1
logtimestamps=1
maxconnections=256
#---- masternode settings
masternode=1
masternodeaddr=37.139.12.133:9999
masternodeprivkey=xxxxxxxx

Yes, if your VPS/dashd was down for more than ~60mins you need to issue a "masternode start" from your cold wallet. Otherwise the masternode dashd should catch up to where it stopped

I think it was around 2 hours downtime :-<
I hope this was 'beginners luck", I really thought DigitalOcean was a solid provider.

I can't comment on DigitalOcean, but my record downtime on one of my VPS providers is 16hrs - without any notification from their helpdesk

I really haven't had any problems with DigitalOcean. Maybe you just had bad luck?

I've installed splawik's MN watch script and run it with cron every 10 minutes and at reboot and it's worked a charm. I haven't missed any payments for months.

# start dashd if not running
if [ -z `/bin/pidof dashd` ]; then
  /home/nmarley/current_dash/bin/dashd
fi

In my crontab:

@reboot /home/nmarley/mn-watch.sh
*/10 * * * * /home/nmarley/mn-watch.sh

Could you point me in the direction of splawik's MN watch script? Thanks!

 

[nmarley]

Yep:

# start dashd if not running
if [ -z `/bin/pidof dashd` ]; then
  /home/nmarley/current_dash/bin/dashd
fi

That's it in it's entirety. Replace "/home/nmarley/current_dash/bin/dashd" with the full path to your dashd binary. Call it something like: mn-watch.sh and do as I explained above with the crontab. Replace paths as necessary (e.g. your server won't have an "nmarley" directory).

naruby: Just remembered something. Did you set up a swap partition on your DO droplet? They don't do it by default, and it will drop processes (like a modem drops packets) on a 512 MB node if you don't have a swap partition setup.
