trying to clone a zfs file system on the same system using
zfs send -r root/branch@snapshot |zfs receive root/newbranch
and get the following error
:parent does not exist.
How do I fix this?
It is telling you this object
root/branch@snapshot
is from a filesystem with no parent e.g. / - the root directory. You cannot "fix" it AFAIK.
There are workarounds like clone.
zfs snapshot root/branch@snapshot zfs clone root/branch@snapshot root/newbranch/
This copies the whole dataset from root/branch to root/newbranch # -> root/newbranch is the new dataset
