I am planning a bare metal installation of FreeBSD 12-rc3 in my desktop with 6GB DDR3 non-ECC RAM and core i3-2120 based system. My concern is in a rare case of power failure, how well UFS2 will work? Is it as easy as running fsck on an ext4 file system in Linux, for example?
ZFS is confusing for me, as a desktop user. Firstly, no ECC RAM. Since I am going to dual boot with Linux, I cannot give a whole disk to auto-create ZFS pool and related.
What will work best in my case? Will ZFS keep hard drive activity high resulting in HDD life? The author of FreeBSD books Greg Lehey hinted, he will stick with UFS2 only. Will anyone guide me, I have created free space in the hard drive. I have to use gpart to create the ZFS or UFS2 file system and manually complete the tasks. But, for an average user, is ZFS really needed? and will UFS2 fsck reliable in case of power failures.
