Question

Hi Guys,

Multipath call failed exit. This warning occurs in the Compute log of my instance.

WARNING nova.storage.linuxscsi [req-cac861e3-8b29-4143-8f1b-705d0084e571 admin admin|req-cac861e3-8b29-4143 8f1b-705d0084e571 admin admin] Multipath call failed exit (96)

Is there any wrong with my compute system?

Thank You

Hi@akhtar,

This warning occurs in the Compute log if you do not have the optional multipath-tools package installed on the compute node. This is an optional package and the volume attachment does work without the multipath tools installed. If the multipath tools package is installed on the compute node, it is used to perform the volume attachment. The IDs in your message are unique to your system.

Install the multipath-tools package on the compute node.

$ apt-get install multipath-tools //Ubuntu

$ Yum install multipath-tools //CentOS/RHEL

Hope this will help you.

Thank You
