Hi Olgert,
Thanks for reporting. For some reason the SSH connection dropped which
unfortunately the code doesn't handle well as you experienced. I need
to implement some sort of auto-reconnect (with a cap on the number of
retries) to fix this.
- From your log it looks the volume was created but never resized. You
have a couple options in that case:
1. Delete the new volume and auto-generated snapshot of the original
volume and try again. No need to terminate the volhost cluster in this
case - it will be reused on the next launch.
2. If you still have the new 500GB volume you can simply attach it to
an instance and run resize2fs on the device to finish the job. It's
also safe to delete the auto-generated snapshot of the original volume.
HTH,
~Justin
