[07:42] <dave> Hi guys
[07:43] <dave> I do have a percona cluster running well (3 members), I do need though to change the innodb_buffer_pool_size, my problem is that to do o via juju config , it does shutdown the whole cluster. Which I would like to avoid.
[07:44] <dave> I can change the value in the .cnf file and restart each node (will be fine), except that juju might re-apply the value set in the charm config.
[07:44] <dave> I would say that if I could change that value without triggering any action would be great.
[07:45] <dave> Is there a way to get into the mongodb maybe to change that value?
