Ok, ali moze doci do corruptanja particije i onda je kaos. Nestanak struje i takve stvari nisu bas dobre na tom sistemu.
WARNING: to ensure consistency for the checksumming and parity calculations performed by ZFS, ECC RAM is highly recommended. Using non-ECC RAM can cause unrecoverable damage to a zpool resulting in a loss of all data in the pool.
If you don't have at least 8GB of RAM with ZFS or 2GB of RAM with UFS, you should consider getting more powerful hardware before using FreeNAS® to store your data. Otherwise, data loss may result.
