Hello,

How to mount a JFS harddisk partition in FreeBSD ?

blkid returns:
Code: 
....da0... : UUID="700ae18e-c633-4542-8156-5bb5d4d379d5" TYPE="jfs" PARTLABEL="backup16" PARTUUID="....


Thank you in advance and kind regards,

No seriously, Linux for just JFS ??
JFS is very old.


Linux apparently has JFS support, but from the posting below they are
incompatible. Someone at work told me that OpenBSD or NetBSD should be able
to mount these filesystems. I've also come across a FreeBSD JFS port on
sourceforge. http://sourceforge.net/projects/jfs4bsd


jfs not even in openbsd: https://misc.openbsd.narkive.com/o5GbJKfW/other-fs-support-in-openbsd
seems that netbsd goes a bit jfs : https://wiki.netbsd.org/projects/project/jfs/





Overview​

IBM's journaled file system technology, currently used in IBM enterprise servers, is designed for high-throughput server environments, key to running intranet and other high-performance e-business file servers. IBM is contributing this technology to the Linux open source community with the hope that some or all of it will be useful in bringing the best of journaling capabilities to the Linux operating system.


Linux Distributions shipping JFS​

The Linux distributions that ship JFS, along with the initial version in which JFS was available, are included in the following table:

This table isn't being kept up to date do to the face that the filesystem is available in just about every distribution. It remains for historical reasons.

FreeBSD's native UFS is actually older than IBM's JFS. So? I trust much of my data to UFS today (even though for large file systems I use ZFS). When I worked at IBM, I trusted my data to JFS (actually JFS2). Neither have ever let me down.

As far as I know, the IBM-supported JFS version that is in RedHat and SUSE is fully compatible, also with AIX. I don't know about the others.

One more warning: There are other file systems that are also called JFS, but are not identical to the IBM AIX/Linux JFS (a.k.a. JFS2). For example, HP-UX also had a file system called JFS, but I don't remember the details of what it was. And I think early during the development of Linux, the name JFS was used for something else (for some bizarre reason, I remember that Stephen Tweedie was involved).

Install a VM using bhyve with your Linux distribution of choice, mount the partition and export it via NFS.
