OK, after confirming we don’t have msgqueue enabled I don’t think we’re affected at all.

But for the sake of clarity, we have nodes at, but the filesystem release is at – and it appears the filesystem version is the important one here.

Many thanks,

Hi Luke,

All are required. The reason for the discrepancy in the second statement is because the filesystem version of or higher is a checked pre-req to running the 'mmmsgqueue config --remove-msgqueue' command.
