Reflink
|
||
-------
|
||
|
||
bcachefs supports reflink, similarly to other filesystems with the same
|
||
feature. cp –reflink will create a copy that shares the underlying
|
||
storage. Reading from that file will become slightly slower - the extent
|
||
pointing to that data is moved to the reflink btree (with a refcount
|
||
added) and in the extents btree we leave a key that points to the
|
||
indirect extent in the reflink btree, meaning that we now have to do two
|
||
btree lookups to read from that data instead of just one. |
