Can you please investigate?

Thanks

It looks like a configuration issue on the RHEL8 client node.

The command that fails is:

$PDSH ${uname}@localhost "openfile ..."

On RHEL7.6 client nodes in Jenkins, such pdsh command works.

[Sebastien Buisson]

I opened DCO-8348 to report this pdsh problem.

[Minh Diep]

keep in mind that the report on this ticket is from manual testing uploaded, not from autotest

[Sebastien Buisson]

Oops, sorry

 

So my recommendation is to allow 'pdsh localhost' on client node running this test.

[Jian Yu]

Since the command needs to be run on local client, it seems we can just use $RUNAS instead of $PDSH, so that user do not need to configure "$PDSH ${uname}@localhost".

[Wang Shilong (Inactive)]

I agreed with Jian, we hit the failure too locally testing, just running $RUNAS might be better.

[Sebastien Buisson]

No, $RUNAS is not a substitute.
As explained in https://review.whamcloud.com/34809, I tried with runas, but it does not work, because it only substitutes the UID and GID.

However, if you are able to find an alternative to $PDSH that makes sanity test_420 pass, I would be glad to use it.

[Sebastien Buisson]

It turns out that a simple alternative is to use 'su - $uname -c'. I will push a patch with this fix.
