Openstack dashboard gives error “Error: Unable to retrieve information”

So today i ran into one more issue with Openstack , the error showed up  when i logged in to the dashboard and clicked on Project–>Instances.

What i saw terrified me because is saw “NOTHING” !

A day before i had the same issue and i thought it’s related to RAM so i restarted and everything started and operated normally, but this time the reboot didn’t help.

So i started scratching my head and started wondering what might be the reason. I searched internet but no success. I searched log files but nothing made sense at that time, so i rebooted one more time and an Error appeared saying something like “Openstack glance-registry api error limit reached ” So that gave me a head start that it has something to do with system being low in space.

A df -h showed that / is 100% full. I removed some unnecessary files , rebooted the system and Viola !

All started to work Normally.

Conclusion:

Make Sure you have enough space with OpenStack

So, take a look on my workaround… Continue reading

My favorite web-based tools for web design

Hey guys,

Today I want to share the tools that I use for different purposes in my web design. Some of them seem abandoned and a little outdated now, but they still serve the purpose. The thing is that it’s web 3.0 and interactive web pages has turned into full blown applications and now you don’t even need most of the software you couldn’t live without in past (remember Dreamweaver or Flash? =)))) Continue reading
