maas node times out after during juju bootstrap

  • 772

I have 6 nodes that have all been commissioned. I can ssh to 2 of them with ubuntu@ip_address. The other 4 fail to ssh with

Permission denied (publickey)

Juju deploy fail with

Failed to query node's BMC — Node could not be queried node-3c9e137a-744c-11e4-a75c-180373b04ac9 (esxi10.local) connection timeout.

I have added ntp runs during startup and via cron via commissioning scripts. I have even tried adding a second account, complete with password and public keys, but I can't log into these either.

Why would some machines commission correctly and others not? Any ideas?

  1. The problem appears to have been caused by the physical clocks being not in sync enough with the server and critical parts of the commissioning happen before they run ntpdate. I installed 3 commissioning files to sync ntpdate and the hardware clock.

    01-ntpdate - syncs with ntpdate and then writes to the hardware clock

    #!/bin/sh<BR>
/usr/sbin/ntpdate -v 143.207.7.23<BR>
/sbin/hwclock -w

    01-ntpdate-cron - installs a cron job to sync type every 15 minutes and set the hwclock

    #!/bin/bash    
cat <<EOF >/etc/cron.d/ntpdate
0,15,30,45 * * * * /usr/sbin/ntpdate 143.207.7.23 && /sbin/hwclock -w
EOF

    01-S10ntpdate - installs a boot up script to sync time (and hwclock) on bootup

    #!/bin/sh -e
cat <<EOF >/etc/init.d/ntpdate

#!/bin/sh -e
/etc/init.d/ntpdate
/usr/sbin/ntpdate -v 143.207.7.23
/sbin/hwclock -w
exit 0
EOF

chmod +rx /etc/init.d/ntpdate
ln -s /etc/init.d/ntpdate /etc/rc2.d/S10ntpdate 
ls -l /etc/init.d/ntpdate /etc/rc2.d/S10ntpdate
exit 0

    After adding these 3 commissioning files, the first commissioning installs them and actually sets the hwclock (and usually fails the commissioning because the fails before it actually sets the time correctly). The next commissioning runs successfully.

  2. Also, set up a local ntp server, and in /etc/maas/preseeds/preseed-master look for: d-I clock-setup/ntp-server string ntp.ubuntu.com and change ntp.ubuntu.com to your ntp server's IP or machine name.
