    UFS Slow real disk write results

    On the same machine (Lenovo ThinkCentre M600 Tiny Thin Client N3000 terminal), installing pure FreeBSD 14.1 (UFS fs) and Debian (EXT3 fs) distributions, the disk performance results are dramatically different. Result from dmesg (FreeBSD): ada0 at ahcich1 bus 0 scbus1 target 0 lun 0 ada0...

    UFS UFS file system with/without journaling. Which is better?

    ...to journal user data as well, then use gjournal. Their paradigms are different. Talking about different paradigms, all other filesystems, i.e. EXT3/4, XFS, NTFS, JFS, BTRFS, and ZFS, only use the journal for metadata writes, just like su+j does with (file deletes). None of them journal user...

    Solved Reformatting NAS drive to UFS, but what FS for spare drive for FreeBSD from Linux?

    I don't know. The ZFS port for Windows is brand new and I never tried it. It certainly integrates with the drive system. It is reported as basically working. You could mount readonly if you are afraid of data corruption.

    Solved Reformatting NAS drive to UFS, but what FS for spare drive for FreeBSD from Linux?

    Could I mount a ZFS partition/drive on Windows easy (like it just showing up as a drive in Computer/explorer)? I haven't messed with other filesystems on Windows in years but I recall needing a 3rd-party driver for ext3/4. I'd probably only use it under Windows 10 (21H2) or 11 (24H2+).

    UFS UFS file system with/without journaling. Which is better?

    ...better in some cases while GJ was better for others. You can't make blanket statements like this. We also need to keep in mind that su+j, ZFS, EXT3/4, XFS, JFS and BTRFS journal metadata only. Gjournal is a block level journal. It journals everything. Metadata and data. Yes, with GJ there is...

    ZFS How to mount external linux (ext4) sata disk on FreeBSD with ZFS, so the files can be accessed and copied.

    FreeBSD with external storage disks (fs)

    How mature is FreeBSD for reading file systems? It is perfectly possible to read/write file systems such as ext3 and ext4, using the ext2fs module that FreeBSD provides. However, I saw reports here on the forum that using ext2fs would be risky, due to the risk of data corruption or any other...

    mounting ext4 drive in 14.0

    I will need to get a linux pc first. Thanks this far

    mounting ext4 drive in 14.0

    Says it all. You need to put it in Linux and recover or delete the Journal. The only way to use ext3/4 on FreeBSD is to disable Journal. Otherwise FreeBSD corrupts it.

    Other EXT4 wrong magic number mount error

    Please tell us more detail. How did you format the file system on the partition? Hint: I would never trust non-native file systems, other than in read-only mode. If you want to create an ext<n> file system, do so on Linux. What file system type did you actually create, ext2 or ext4? How did...

    ...between FreeBSD and Linux. Update: I've decided to do exactly the same steps as described before with two minor modifications: Create an EXT3 partition, write a "test" directory to it. Go to Linux plug the drive, copy some files and get the drive back to FreeBSD. Now I'm able only to mount...

    Other I'm con-FUSE-d

    This is the answer. All modern linux use Journaled ext3 and ext4. Simply turn it off on Linux end and our stuff works. We don't support ext3 or ext4 journaling. Writes crash the fs journal and needs mending in Linux after attempted writes from FreeBSD..

    You've been doing FreeBSD for some years now - you should know how to check. FWIW here are the "ext2fs" man pages root@kg-core2:~ # apropos ext2fs ext2fs, ext4fs(5) - ext2/ext3/ext4 file system fsck_ext2fs(8) - compatibility wrapper for e2fsck

    Which man page exactly? fusefs-ext2 fusefs-ext4fuse fusefs-lkl How do I check? Could my problem be related to UUIDs?

    Other I'm con-FUSE-d

    From the man page "It currently implements most of the features required by ext3 and ext4 file systems. Support for Extended Attributes in ext4 is experimental. Journalling and encryption are currently not supported.". Check if your ext4 fs uses any of the unsupported features.
