Migrating files from ceph fs from cluster a to cluster b without low downtime

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

we will have to copy all data

from: hammer cephfs

to: jewel cephfs

and i would like to keep the resulting downtime low for the underlying
services.

So does anyone know a good way/tool to make a "pre" copy of the files
and then just copy the delta's since last copy ?

Thank you !
