How we fix the error ‘glusterfs transport endpoint is not connected’?

Recently, we came across an error relating to GlusterFS.

The customer wanted to verify about whether the write/read ops permission when one storage node is down.

After killing the gluster processes on one of the non-arbiter nodes (using pkill ^gluster*) the client mount point fails with the error message.

Transport endpoint is not connect

Glusterfs-client is already set on Ubuntu. Here is the Gluster volume information in the screenshot.

We found that the operations on the client-side fail with this error message.

Our Support Engineers started troubleshooting the error by checking the glusterfs-client log file.

Then we found that these additional options were set:

gluster volume set brick01 cluster.quorum-reads false
gluster volume set brick01 cluster.quorum-count 1

Also, we found that by default arbiter brick was failing to heal (sync) simultaneously when any file operation occurs. So we reconfigured the option ‘cluster.self-heal-daemon by running the below command.

gluster volume heal brick01 enable

This finally, fixed the error.
