My use case - from past ages /mail is block device for kvm vm. Now I
need more space for messages, but I don't want use 3x raw space for
replicas.
What is your reccomendations? Create an RBD image on an erasure coded
pools when a replicated pool tier set a cache tier?
Thanks.

I wouldn't use CephFS for so many small files. Dovecot will do a lot of
locking, opening en closing
Hello.
How your tests? I'm looking for CephFS with EC for save space on
replicas for many small files (dovecot mailboxes).
Thanks everyone for the input. We are online in our test environment and are
running user workflows to make sure everything is running as expected.

Thanks for the confirmations of what is possible.
We plan on creating a new file system, rsync and delete the old one.

I use CephFS on erasure coding at home using a cache tier. It works fine for
my use case, but we know nothing abo

In the current released versions, you cannot use erasure coded pools with
CephFS, unless there is a replicate
Two questions on Cephfs and erasure coding that Google couldn't answer.
1) How well does cephfs work with erasure coding?
2) How would you move an existing cephfs pool that uses replication to erasure
coding?
