Quantum storage devices may have a known Linux bug

Challenge

To identify if a known linux bug is the cause for errors on a backup repository.

Cause

You will see a job fail with  “unable to mkdir /var/log/sudo-io : File exists”, this is caused by a bug in some versions of the sudo application.

Solution

Some quantum storage device’s operating systems are based on RHEL 6.8 and may have the bug referenced here:  https://bugzilla.redhat.com/show_bug.cgi?id=1365156

1st check the version of the sudo application by logging in to the storage device os by ssh, and run “sudo -V”
If the version returns sudo-1.8.6p3-24.el6.x86_64 or older then it is affected by the bug. The issue is fixed in sudo sudo-1.8.6p3-26.el6

Quantum will need to update this as their os is a custom version of RHEL.

End users should refer their Quantum engineer to Quantum case 410352.
