    UFS UFS: zeroing free space

    With UFS: how best to write zeros (or whatever) into free space? In this case: to allow better compaction of the underlying virtual disk. (Above: 73 G, compacted, for a system that uses only 12 G.)

    Other Format for a second disc

    I was planning to use a second hard disk as a backup for documents and files. I'm not sure what format to use ext4 / ntfs / ufs to be able to access it from FreeBSD and Win10 since I have dual boot. When I was using Linux I used a program from Windows to access ext4., But with ufs I don't know...

    FreeBSD-provided disk images: problems with UFS, fsck_ufs (fsck_ffs(8)); partition sizes …

    Why not ZFS by default? Images are compressed before distribution. I assume that compression is very effective for: non-used space (free, never used) in file systems non-used swap space. Why is there so little free space in the file system for the base OS? Why is so little of the disk given...

    Hi all, After 13.0 is released and the dust settles down, I'm going to move my workstation (mostly used for neuroscientific computations with R, Julia and Python) from Debian to FreeBSD (this will be my very first time with the system). I have several questions regarding the process, but first...

    UFS Why I am using UFS in 2021.

    I am a relatively new user of FreeBSD. For the past 15 years I have been managing a small server farm all running Debian or Ubuntu. Not thrilled with the way these distributions have been progressing, so thought I would give FreeBSD a whirl. Some things in particular that piqued my interest are...

    Hello, I have a physical FreeBSD server I installed using ZFS on root. To ease maintenance I'd like to move it into a virtual machine (VMware ESXi), but since virtualizing ZFS is not recommended, I would like to convert it to UFS. Here's my plan so far, can anyone confirm whether I am on the...

    What Do YOU Use FreeBSD For, and Do You Use UFS or ZFS? :)

    I use it for development, you know, Programming 'n stuff... :) I also use it for ZFS, since I keep backups of my friends' and family members' data. :) I also use it for other things, like when I use Linux, but want more of a UN*X-y feel. It also speaks to how good of an OS it is when I...
