How to mount OS/2 JFS/LVM volume on Linux?

[Andi B.]

I wanna access my OS/2 volumes from Linux/Debian12. But can't 'click' and automount like in any GUI file manager. For my FAT32 and NTFS partitions I see the label in Linux and clicking on them opens the volume/filesystem. But not with my JFS volums. Any help?

I've already installed jfsutil and libguestfs-jfs.

Hi Andi!

Get the id of your partition ( e.g. /dev/sdi1)
open a command window and then:
->  sudo mkdir /media/jfsos2    (or other name to define your mount point)
->  sudo mount -t jfs /dev/sdi1 /media/jfsos2
->  If it fails, may be alignment isn't ok under linuw (I have miss aligned partition for one of all despite all where created under OS/2  ARcaOs LVM

note: To trim in case of an SSD.
Once the partition is mounted:
->  sudo fstrim -v /media/os2jfs

Hope this is helpfull

Ok, thanks. Now I get further. I found one JFS partition/volume mounted at /media/a/e97c5ffe.......  But user 'a' can not cd into this directory. Only root. Maybe I can temporary change chmod for this dir. But for all the NTFS/FAT32 volumes there is some automatic 'mount with access rights for all users. See -

Also most of my JFS partitions can not be mounted. Bit hard to find which one is which OS/2 volume cause currently I've more than 20 volumes here.
Also for the NTFS and FAT volumes the labels are found and mounted with these. Not some long number....

To find which partition, checking the partition size can be helpfull
