When creating a multi instance brokers, some of the folders are managed at the shared folder, and stay on the local disk.
unfortunately, the shared classes folder stays local, and from obvious reasons I want it to be shared.
Changing the workpath folder is possible with adding the -w parameter to the mqsicreatebroker command, but is it a good idea to make the workpath folders shared, beyond what the -e parameter (creates a multi instance broker) does? the documentation does not says explicitly you CANNOT, but it also does not say you CAN. |

Well, I gave it a shot.
Broker creation and failover were successful. Adding the -w parameter the way I did it means that now node_modules (which I don't use) , shared-classes (profit) and common folders are now shared between the integration nodes as well.
Could it be I outsmarted IBM? |

No one outsmarts the Cobalt Collossus

@Vitor
Still, not moving the shared classes folder to the shared storage when creating a multi-instance broker is awkward decision by IBM. |

Never said it wasn't, and it joins a long list of awkward decisions IBM have made over the years on this and every other product in it's portfolio. I'm thinking especially of an "awkward decision" they made in the z/OS COBOL 2 compiler that at the time I wanted to discuss with the development team in IBM repeatedly and quite hard. Ideally while armed with a 2x4. Fortunately, and without fanfare, the decision was amended in COBOL LE/370 and many lives were spared.
My point is that trying to bend an IBM product / using an undocumented feature / kludging some kind of workaround is a very dubious course of action.

I mounted /var/mqsi/shared-classes folder, after licence acceptance, on shared storage for both servers, keeping the path unchanged. seems like it works.
**EDIT** And keep read/write permissions as well!
Legit workaround?

Is it documented?

Then you answer your own question. If it's not documented, it's not legit.
