OS X 10.7.4 Şifreleme için Çekirdek Depolama, ZFS için ZEVO
Misal
Amaç: bir fiziksel disk, beş birim. Şifrelenmemiş beş taneden biri, biri parola ile şifrelenmiş, üçü farklı bir parola ile şifrelenmiş.
Başlangıç noktası:
- / dev / disk2 - fiziksel bir disk
- / dev / disk2s2 - korunacak, korunmayan JHFS + birimi
- / dev / disk2s3 - imha edilecek, şifreleme ve ZFS ile yeniden kullanılacak bir dilim.
İpuçları
Yana HFS + tüm meta veri güncellemeleri için tek bir küresel kilidi vardır (I genelinde düzenlenen G / Ç) o diski gecikmelerinde karşı oldukça duyarlıdır . Yani tek bir diskte JHFS + ile ZFS karışımı iken ise mümkün çoğu kullanım durumları için dosya sistemi karışımı olup, değil önerilir.
Bu örnek aynı zamanda sıkıştırmayı ve alt dosya sistemlerini biraz kullanır.

Bilinen Sorunlar
CoreStorage dünyasında içerik ipucu Apple_HFS
, ZFS
sonuç için doğru olmayacaktır . Apple'dan daha uygun bir ipucuna izin vermesini istedim.
Kilit açma zamanında, sistem parolayı reddetmiş gibi görünebilir (belki içerik ipucu uyuşmazlığı nedeniyle). Ret göründüğünde:
- Bekle
- kilidi açılmış birim (ve alt dosya sistemleri)
- şifre diyalogundan kaçmak.
İsterseniz, bir Core Storage mantıksal biriminin UUID'sinin parolasını bir anahtarlığa eklemek için Anahtarlık Erişimi'ni kullanın.
Mountain Lion artık diskutil eraseDisk
çekirdek haritaların Çekirdek Depolama mantıksal birimlerine yerleştirilmesini desteklemiyor -

- uyarı için mgrosman'a teşekkürler .
tamirat
Apple'ın Core Storage tasarımını öncelikle içerik ipucuylaApple_HFS
ve fsck_cs'deki hatalarla çalışmak için göz önünde bulundurarak :
- Ben alternatif tip 'zorlama' olmadığını (bilmiyorum
ZFS
, zfs_pool_proxy
, zfs_filesystem_proxy
vb) yeteneğini bozabilecek fsck_cs
zorluk durumunda etkisi onarım.
Dikkatle ilerle.
