Partition opt on fabric interconnect a has file system errors

[Walter Dey]

After a painful recovery downgrade (failed upgrade from 2.2.3d to 2.2.6d) everything is working again, however I see

Partition opt on fabric interconnect a has file system errors (see attachment)

Any hints to fix this nasty error are appreciated.

Hi Walter,

the error you are seeing , looks some /opt got corrupted during the downgrade. you can try this:: connect to Fabric Interconnect using the debug plugin and perform an fscheck of the file system though most of the time , we have to end up replacing the FI.

another possible solution::

We could do an init system on the FI. This would pretty much be a complete
rebuild of this FI and should resolve any file system corruption. That would require
downtime on that half of the fabric, so definitely best during a maintenance window.

**you can raise a TAC case to assist you in performing this activity or for replacement..

Thanks-

Afroz

Thanks Qiese and Afroz

Very much appreciated !

Q. is there any risk doing a fscheck ?

Problem: customer doesn't have a maintenance window for next 6 months.

I think after all, a RMA procedure might be the preferred method, although it requires of course to rack, and cable the RMA box; the synch of the firmware and configuration usually works ok.

Walter,

Have you consoled in to the fabric interconnect with the issue yet? It might be stuck in the loader prompt / configuration page.

Good morning Walter,

The bug you are running into is;

I have ran into this issue in the past, TAC will have to load the debug plugin and just check some blocks. As Afroj stated, a initiate system is another fix but that is a longer process, if you open a TAC case be sure to mention the bug listed above and they can attempt that work around first.

Let me know if you have any other questions or need any assistance.
