Comments

[Andreas Dilger]

I think this is a non-bug, as we changed the MDS code to silently convert the too-large DoM component size to be limited by the lod.*.dom_stripesize limit.

Assigning to Mike to verify, but I think this can be closed as "Not a bug".

[Mikhail Pershin]

yes, this is not a bug, should I make a patch for pre-2.12 clients to don't fail?

[Andreas Dilger]

I don't think we will be patching 2.11, ao it probably is not worthwhile. This test should just be added to the EXCEPT list when running 2.11 interop.

what's the next step on this failure?
