perfSONAR User Q&A and Other Discussion

[Alex Moura <>]

Hello,

I verified that the host was very low on free disk space. I don't know how the upgrade did not failed completely.

I deleted old log files to free ~1.3GB on / and issued a reinstall of the packages with the string 'perfsonar' in its names, (while monitoring the disk space):

(Warning: data loss will occur when the commands below are executed).

$ rpm -qa | egrep -i '(perfsonar)' | xargs -n1 -I '{}' echo "yum -y remove '{}' && yum -y install '{}'" | sudo -srpm -qa | egrep -i perfsonar | xargs -n1 -I '{}' echo "yum -y remove '{}' && yum -y install '{}'" | sudo -s

Followed by a reinstallation of cassandra and http packages:

$ rpm -qa | egrep -i '(http|cassandra)' | xargs -n1 -I '{}' echo "yum -y remove '{}' && yum -y install '{}'" | sudo -s

The httpd reinstall failed. So it was needed to install manually:

$ sudo yum install -y httpd-2.2.15-31.el6.centos.x86_64

Then, I restarted both cassandra and httpd:

$ sudo service cassandra restart && sudo service httpd restart

This allowed to access the web gui again, but configurations were reset and all data was lost. 

At first I was unable to login in the "Administrative information" because of certificate problem. 

After a login in the root account the script asked to create a web admin account. That allowed to access the configuration in the web interface. The basic setup was reconfigured, but it seems the tests configurations scripts are still mangled:

The on-disk configuration has changed. Any changes you made have been lost.

Maybe reinstalling some additional package will completely recover the host funcionalities?

Thanks,

Dear all,

Have you all tried to run /opt/perfsonar_ps/toolkit/scripts/discover_external_address after upgrading the machines?

It seems the boxes with version 3.4 does not have this script:

[ ~]$ sudo ls -lF /opt/perfsonar_ps/toolkit/scripts/discover_external_address

ls: unable to access /opt/perfsonar_ps/toolkit/scripts/discover_external_address: File or directory not found
