Following the instructions on page 9: http://resources.jamfsoftware.com/archive/Administering-FileVault-2-on-OS-X-Mavericks-with-the-Casper-Suite-v9.2.pdf
4153109:~ admin$ sudo security create-filevaultmaster-keychain /Library/Keychains/ Password: password for new keychain: retype password for new keychain: a4153109:~ admin$ security unlock-keychain /Library/Keychains/FileVaultMaster.keychain password to unlock /Library/Keychains/FileVaultMaster.keychain: security: SecKeychainUnlock /Library/Keychains/FileVaultMaster.keychain: The specified keychain could not be found.
and if we navigate to /Library/Keychains/
FileVaultMaster.keychain is not there. I've repeated this on 3 different Macs running 10.9.5. Any ideas?
your first line, creating the keychain, you didn't specify the actual file name to be created. I did this too the first time because in the document it's carried over to the next line and easy to overlook. Should be:
sudo security create-filevaultmaster-keychain /Library/Keychains/FileVaultMaster.keychain
