Hello
https://docs.ceph.com/en/latest/cephfs/createfs/ mentions a
"default data pool" that is used for "inode backtrace
information, which is used for hard link management and
disaster recovery", and "all CephFS inodes have at least one
object in the default data pool".
I noticed that when I create a volume using "ceph fs volume
create" and then add the EC data pool where my files
actually are, the default pool remains empty (no objects).
Does this mean that the recommendation from the link above
"If erasure-coded pools are planned for file system data, it
is best to configure the default as a replicated pool" is no
longer applicable, or do I need to configure something to
avoid a performance hit when using EC data pools?
Thanks
Vlad
