Another FreeBSD drop into the Digital Ocean

After several happy years with FreeBSD running in AWS I finally have switched to Digital Ocean. That happened a few days ago and was driven mainly by the lack of the console support which “aws ec2 get-console-output”, in my opinion, is certainly not. After the upgrade to FreeBSD 11 I found my instance unreachable and […]

AWS FreeBSD instance won’t come up. Screams for manual fsck.

This is a short write up if after a reset or a reboot your FreeBSD (or Linux) instance doesn’t come online, stalls and “aws ec2 get-console-output” returns something like that among its lines: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. Just power-off the faulty instance either from Web interface or using cli: aws ec2 stop-instances –instance your_instance_id […]

Videos from EuroBSDCon 2014

Jumping into another cloud

After almost 4 years of being a Rackspace user I’ve moved to a new home – Amazon AWS. The main reason that gave me a nudge was the issue I was hit by after upgrading to 10.1-Release. Temporary solution did work but it was too costly to consider it as permanent so I started to […]
