A couple of days ago I submitted a request to ElRepo and kmod-jfs

now available for CentOS 7 as well.
Did not have a need to mount a JFS disk on my CentOS 7 system until
today
and it does not want to be mounted, instead complaining "unknown
filesystem
type 'jfs'". I do have kmod-jfs installed.
The commandline I use is:
mount -t "jfs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb1"
/mnt/share
I am doing this as root and /mnt/share has been created for the root
user.
What am I doing wrong? Does anyone have JFS volumes mounted under
CentOS 7?
The kmod-jfs package needs to be rebuilt against the EL7.4 kernel.
We will update the bug report ( http://elrepo.org/bugs/view.php?id=728 ) when the updated version is ready.

Where does one see which kernel version the release is intended for? I should add that I installed it from elrepo earlier today on a current computer, not some time ago... No error messages.
Try the following command on a computer you had kmod-jfs installed:
$ ls -l `find /lib/modules -name jfs.ko`
It will show where the module was installed (in the extra/ directory) and may show symbolic links to other kernel versions (if any) that are compatible.
In the case of the kmod-jfs package, there was a kABI breakage when going from el7.3 to el7.4. As a result, what was built against el7.3 was broken in el7.4. It has now been built against the el7.4 kernel. This one is not backward compatible with earlier (< 7.4) kernels.
