AIX's JFS can be mounted on Linux. You can just mount it normally using the mount
command if you have JFS drivers installed (and it isn't ,obviously, a spanned volume group).
As I said, CRUX PPC bootkernels have JFS support built-in and jfsutils available (but without ACL).
Anyway the real answer is probably NO.
In AIX operating system, there exist two generations of JFS filesystem that are called JFS (JFS1) and JFS2 respectively. In the other operating systems, such as OS/2 and GNU/Linux, only the second generation exists and is called simply JFS. This should not be confused with JFS in AIX that actually refers to JFS1.
And again, if you still have an AIX partition layout on your system, you will get the following error message using fdisk
to partition your disk:
There is a valid AIX label on this disk.
Unfortunately Linux cannot handle these
disks at the moment. Nevertheless some
1. fdisk will destroy its contents on write.
2. Be sure that this disk is NOT a still vital
part of a volume group. (Otherwise you may
erase the other disks as well, if unmirrored.)
3. Before deleting this physical volume be sure
to remove the disk logically from your AIX
machine. (Otherwise you become an AIXpert).
Command (m for help):
You 'll be able to create a new empty DOS partition table but this will destroy any installed AIX version.
The Linux kernel, as I know 'cause i never tried, isn't able to manage aix partition table.
AIX and Linux can run concurrently in separate partitions on an LPAR-enabled system.
