Hello Wesley.
Thank you for the warning. I'm aware of this and even with the recommended
upgrade path it is not easy or safe for complicated clusters like mine. I
have billions of small s3 objects, versions, indexes etc.
With each new Ceph release, the rados, db, osd, pg projects started to use
new schemas, attributes etc to store the data and index.
Instead of upgrading, I'm gonna export all the data as RAW, destroy the
clusters, wipe the drives and start from scratch.
This is the safe and fast upgrade method for me.
one additional blocker is the choice of the OS on the machines. Certain
ceph releases might only be available for certain distribution versions,
so if you decide to actually upgrade the existing cluster you will
probably also have to upgrade the OS.
Starting from scratch might be the faster solution, if you can afford to
dump all data to a temporary location.
Best regards,
Burkhard
