是否有回退到具有子子卷的子卷快照的规范方法。因此,例如,这是我的btrfs卷布局:
ID 257 gen 59802 top level 5 path __active
ID 258 gen 59784 top level 5 path __snapshot
ID 259 gen 59802 top level 257 path home
ID 260 gen 36538 top level 257 path opt
ID 261 gen 59802 top level 257 path var
因此,您可以看到home,opt和var是__active的子子卷。如果我快照__active,这是我的新布局:
ID 257 gen 59802 top level 5 path __active
ID 258 gen 59784 top level 5 path __snapshot
ID 259 gen 59802 top level 257 path home
ID 260 gen 36538 top level 257 path opt
ID 261 gen 59802 top level 257 path var
ID 416 gen 59784 top level 258 path __snapshot/__active
如果我想回滚到__active的快照,是否可以将home,opt和var重新附加到新的__active?
