Isilon: Upgrade to 8.1.0.4 - Has anyone had an issues?

Good Morning,

It is being suggested, due to a bug in any previous Firmware & OneFS Version, that we upgrade all our clusters to OneFS 8.1.0.4 (from various 8.x version) along with the corresponding firmware. I just wanted to check to see if anyone has had any issues with this upgrade similar to the issues seen during the 7.x to 8.x debacle?

Hi,

We have upgraded from 8.x to 8.1.0.4, no issue reported till now. It’s just

that I feel the job engine is running a bit slow.

FSA job still does not completes

Regards

For what it's worth we've been running it in production for weeks on Gen6 clusters and no issues.

Just to add, I'm using SMB not NFS, so perhaps that's why I haven't been impacted by what Ed posted.

Same thing here. We have 400 NFS clients connected to the Isilon and several times a day  NFS mounts stalls when a few clients do heavy reading and writing. It seems like the Isilon runs out of resources and lowers the TCP window to 0.

Isilon OneFS v8.1.0.4 B_MR_8_1_0_4_057(RELEASE)

Client OS Centos7

Clients are connected via   Mellanox IB to ethernet PROXY gateways

Re: Isilon: Upgrade to 8.1.0.4 - Has anyone had an issues?

Because there was no patch, we wrote a script that runs on the Isilon cluster and drops the wedged sessions.  You'll find sessions stuck in FIN_WAIT_2 state.  You can run /usr/sbin/tcpdrop to kill them.

Earlier releases also have the problem - we have clearly documented it on 8.0.0.6 and 8.1.0.3.

We need to get the patch rolled out but now is not a convenient time for the massive undertaking (over 100 nodes) .  Some days I really dislike Isilon QA

Re: Isilon: Upgrade to 8.1.0.4 - Has anyone had an issues?

I am not sure we are seeing this problem.

We use static NFS mounts and the problem so far more looks like the use of memory mapped files as one side of the problem. And simultaneous reads and write from the same node as another side of the problem. It also seems like the problem does't spread to other nodes even if they are serviced by the same Isilon node.

Do you BTW have a link to document describing the FIN_WAIT_2 issue?

I just discovered today, that the problem we hit is covered by this patch:

Isilon OneFS 8.0.0.7 and 8.1.0.4: NFS becomes unresponsive to specific client requests

But it seems to unavailable to customers without support. Given the serious nature of this problem I simply don't understand this policy.

Has anybody succeeded to download OneFS 8.1.0.4 - patch-228133?

UPDATE:

According to the latest patch list the correct patch is patch-239649 which I was able to download.
