NimbostratusGot this from Martijn and it solved it in our F5: https://cdn.f5.com/product/bugtracker/ID915605.html
NimbostratusYup i got the same answer, so now have upgraded both my boxes, its related to the iRuleLX component being licensed and activated, means that each upgrade from now on will have to remember to perform the remount command before installing the update, and for safety only do it on the offline / standy unit (not sure what remounting /usr read only could potentially do to the live unit, and don't feel like "testing" it on our production kit!)
