Hi Mykola,
Thanks for the explanation. I am exclusively running cephfs and all my
clients use the cephfs kernel driver. So I was reading this:
https://ceph.com/community/new-mimic-simplified-rbd-image-cloning/ but
I don't think this is something I could use. I'm not really interested
in snapshots.
I think I could create a new EC pool, then use a client to copy the data
from the old EC pool to the new one and then remove the old EC.
Subsequently, clients could connect to this new EC pool. This is a long
shot but is this feasible?
I am not very familiar with cephfs and would like someone else
recommend you how to migrate cephfs data from one pool to another.
But if I had to do this I think I would try this way: add the new pool
to the existing cephfs, create a new dir on this fs, using file layout
[1] set the new pool for this dir and move the files here.
