Hi all,

Any ideas on what is the cause of the NFS issues I’m having?

Thanks,
Tommy

Ah great – good to see that it will be fixed soon.

Is this also what is causing the issues with NFS?

Could be, Mohit will get back.

Thanks,
Tommy

+ Mohit
We are aware of this issue and there is a RHBZ [1] filed for it.
We have a plan to fix that in coming 3.7.x release, probably 3.7.15 if not 3.7.14.

Hi all,

I posted earlier concerning rolling back on the version of gluster we are using.

After being successful in doing so I’ve come to realise the issue we were facing may not have been introduced by the latest versions of gluster but are instead an issue with configuration.

We haven’t changed how we were installing and setting up glusterFS but recently we are having issues with SSL, NFS and in turn the log file filling up the root partition.

I’ve attached some relevant extracts from logs below of the issue we are facing (some may not be relevant) – I haven’t been able to find anything in the mailing list that solves the issue.

From glusterd log:

```
[2016-07-20 10:25:31.700017] I [rpc-clnt.c:1004:rpc_clnt_connection_init] 0-snapd: setting frame-timeout to 600

I have also attached nfs.log and glustershd.log

Thanks in advance for all the help!
