Re: Using LIO with Gluster

Hi Prasanna, after all checks I found some minor errors and I discovered that in my test environment the problem is tcmu-runner.service. It doesn't start automatically after boot. I didn't find errors in logs...

If I manually run tcmu-runner.service all star to work properly so the main problem is solved!!!

thank you so much,

Luca

Hi, I'm trying to implement something similar to

https://pkalever.wordpress.com/2016/06/29/non-shared-persistent-gluster-storage-with-kubernetes/

Gluster 3.8.1 and Fedora 24

gluster is up and running. The initiator discover the target but is not able
to find the disk. I successfully tested targetli fileio with the same
target and initiator.
Hey Luca,


Can you attach your /etc/target/saveconfig.json here ?
I doubt the targetcli configuration


Before that quick checks you can do:
* mount the gluster volume and see the target file exist
* targetcli /backstores/user:glfs/glfsLUN info

If you notice the correct signs above, try restarting the
tcmu-runner.service and target.service.

I remember there was a similar situation for me, nothing above worked,
I have rebooted the target nodes and flushed the iptables then it
worked.

I tried also with tcmu-runner 1.1.0

Any help would be appreciated.

Thanks, Luca
