标签:10.10   core storage   dp2   

上一篇说到,安装完10.10 DP2之后,在显示每个分区的磁盘工具中,各个分区看着有些异样,这是因为它把原来的普通分区转化为了Core Storage了。

下面是我安装在普通Mac3 (disk1s5)分区之后,磁盘的内部情况。参考我前面的三篇blog(OSX: 逻辑卷管理系统Core Storage(1)OSX: 逻辑卷管理系统Core Storage(2)OSX: 逻辑卷管理系统Core Storage(3))来看即能看懂。


下面是运行diskutil list的结果,原来disk1s5处的Apple_HFS Mac3的地方被Apple_CoreStorage 的取代了,多出了一个disk2的Apple_HFS X.10dp2(注:X.10dp2是我把Mac3改名的结果):

/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *120.0 GB   disk1
   1:                        EFI                         209.7 MB   disk1s1
   2:                  Apple_HFS X.93                    29.5 GB    disk1s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk1s3
   4:                  Apple_HFS Mac2                    30.0 GB    disk1s4
   5:          Apple_CoreStorage                         19.5 GB    disk1s5
   6:                 Apple_Boot Recovery HD             650.0 MB   disk1s6
   7:                  Apple_HFS Mac4                    29.3 GB    disk1s7
   8:                  Apple_HFS Test                    9.9 GB     disk1s8
/dev/disk2
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS X.10dp2                *19.0 GB    disk2



这个是查看disk1s5的结果,可以看到它的原名叫Mac3:

<span style="color:#009900;">$diskutil info disk1s5</span>
   Device Identifier:        disk1s5
   Device Node:              /dev/disk1s5

这个是看disk2的, Media Name处的名字是磁盘的名字:
$ <span style="color:#009900;">diskutil info disk2</span>
   Device Identifier:        disk2
   Device Node:              /dev/disk2

这个是看Core Storage的:

一旦转化为使用Core torage目前来说,在磁盘工具中,整个磁盘上的所有分区就无法再改变大小了!!!只能用终端命令了-这也是为什么好多人无法改变分区大小的原因之一。


预期:Core Storage在新版本中可能会担当重任,有可能会发布第一个正式版本,而磁盘工具应该也会支持对Core Storage的更多功能,比如改变分区大小,创建新分区等等。


让咱们翘首以盼,抑或拭目以待吧。
