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

 

Word Press Plugin Install Error

Hey Guys , so i installed WordPress on Centos 7 and it was successful, but then i faced an Error while installing the plugins. The Error was “Unable to locate WordPress Content directory (wp-content”

It asked to connect with FTP , but kept on failing.

Solution:

Just Give apache permission to www directory and the content beneath it.

[root@itpings]# chown -R apache.apache -R www/ <--- Now Restart httpd [root@itpings opt]# systemctl restat httpd.service <-- Now Try to download the plugin and should work. Thanks, Salman Francis.
