拆分 ZFS 克隆？

Question

是否可以拆分 zfs 克隆以允许破坏原始快照？

# zfs create zpool1/test1
# zfs snapshot zpool1/test1@snap1
# zfs clone zpool1/test1@snap1 zpool1/test1clone
# zfs destroy zpool1/test1@snap1
cannot destroy 'zpool1/test1@snap1': snapshot has dependent clones
use '-R' to destroy the following datasets:
zpool1/test1clone
# 

在这一点上，它想“实现” zpool1/test1clone 文件系统，基本上就像我执行了zfs send zpool1/test1@snap1 | zfs receive zpool1/test1clone.

Answer 1

如果您不希望子文件系统和父文件系统之间有任何联系，则必须执行 zfs 发送/接收。

Answer 2

您需要将 ZFS 克隆提升到文件系统，以便能够销毁原始快照/文件系统。

zfs promote zpool1/test1clone

zfs promote filesystem
     Promotes a clone file system to no longer  be  dependent
     on its "origin" snapshot. This makes it possible to des-
     troy the file system that the clone  was  created  from.
     The   clone   parent-child  dependency  relationship  is
     reversed, so that the "origin"  file  system  becomes  a
     clone of the specified file system.
