Network and Storage Protocols
Our environment had a new issue introduced with servers we've upgraded from RHEL 7.5 to RHEL 7.6.
IF the server meets the condition where there are no current NFS mounts to our FAS, the following delays occur on a RHEL 7.6 system:
Can be reproduced on 7.6 servers, but doesn't occur with 7.5 or our 6.x servers.
Anyone else able to reproduce such behavior?
If we take a simultaneous packet trace from NetApp and RHEL client reproducing the good and bad scenario, we can find what is the reason for the delay seen with different client versions.
Since ONTAP code is same but with different client versions we notice different delays, this looks to be some change in the client which could be causing this.
I would suggest to open a ticket so that support can look at the packet traces , compare and provide an analysis.
Sure. Please open a support ticket with us and we can provide more details after reviewing the trace on where the delay is coming from.
