Use an SSD boot drive and keep Users on an encrypted data drive
Authored by: FlavioB on Dec 27, '12 08:59:51AM

Hello there.

I wanted to encrypt my second HDD (which is mounted as /Users) and did the following:

created an admin user with full rights (administrator)
put the admin homedir onto the SSD (system disk)
logged out from my user
logged in with admin user
executed in a terminal "diskutil list", and identified "disk2s2" to be my data hdd:

MacBook:~ admin$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *256.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_CoreStorage 255.2 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: Apple_HFS SSD *254.9 GB disk1
/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.1 GB disk2
1: EFI 209.7 MB disk2s1
2: Apple_HFS Macintosh HD 499.2 GB disk2s2
3: Apple_Boot Recovery HD 650.0 MB disk2s3

Then I started the process with:

MacBook:~ admin$ diskutil coreStorage convert disk2s2 -passphrase MYPASPHRASE
Started CoreStorage operation on disk2s2 Macintosh HD
Resizing disk to fit Core Storage headers
Creating Core Storage Logical Volume Group
Attempting to unmount disk2s2
Switching disk2s2 to Core Storage
Couldn't unmount disk2s2; converted volume won't appear until it's unmounted
Core Storage LVG UUID: 2891D42A-3C61-49E7-85AD-CD49563A98FE
Core Storage PV UUID: 2B2C9016-E92A-49C1-8B53-74610EA660FB
Core Storage LV UUID: ABCF84E7-1753-4203-A70E-258D70C2D826
Finished CoreStorage operation on disk2s2 Macintosh HD
Encryption in progress; use `diskutil coreStorage list` for status

Now more than 5 hours have passed and the "diskutil coreStorage list" is still telling me that the status of disk2s2 is "checking":


+-- Logical Volume Group 2891D42A-3C61-49E7-85AD-CD49563A98FE
=========================================================
Name: Macintosh HD
Size: 499248103424 B (499.2 GB)
Free Space: -none-
|
+-< Physical Volume 2B2C9016-E92A-49C1-8B53-74610EA660FB
----------------------------------------------------
Index: 0
Disk: disk2s2
Status: Checking
Size: 499248103424 B (499.2 GB)

Is this correct? What should I do now? Or what did I wrong?

Thanks for your help!

F.
