Hi Frank, Patrick,

I tried to create a cephfs elsewhere and got the warning, that's what got my attention. Nothing is broken, but I thought it could have impact on performance.

Very good to know it's not that bad!

Thanks!!

Kenneth

I read in some release notes it is recommended to have your default data
pool replicated and use erasure coded pools as additional pools through
layouts. We have still a cephfs with +-1PB usage with a EC default pool.
Is there a way to change the default pool or some other kind of
migration without having to recreate the FS?
Not until something like  [1] is implemented.

If it's not broken for you, don't fix it.
