So a decent HBA. There is an issue with some missing drivers but not for this.
If you have watched the forums there are loads of people saying that they have issues with the first release of Dragonfish.
All new versions have bugs, but my impression is that Dragonfish has more than Cobia.
Cobia is stable - there are some issues with GUI reporting that won’t be fixed until Dragonfish but not AFAIK with pools.
So personally my general advice (as a non-expert) is for people to avoid Dragonfish for existing systems unless they don’t mind a possible abortive upgrade, and to stick with Cobia for the moment. Many of the reported pool problems do not seem to have fixes in 24.04.1 which is imminent, so personally I think we need to remain patient and see what ixSystems does about all the people reporting pool problems.
ixSystems position on upgrades can be found on their Software Status webpage and effectively I am saying that existing production boxes should follow the Conservative recommendations on this table.
See also the question I asked in When to upgrade to Dragonfish? and feel free to add your own issues there.
