Re: Cephfs: Migrating Data to a new Data Pool

hi, i made a tool to do this. it’s rough around the edges and has some
known bugs with symlinks as parent paths but it checks all file layouts to
see if they match the directory layout they’re in, and if not, makes them
so by copying and replacing. so to ‘migrate’ set your directory layouts and
then run this tool to move everything to the right places.

i’m unaware of another way of doing this so if there is someone tell me!
