[opensuse] Linux RAID and different version of openSUSE

I have an 11.2 system with a software raid disk set. The disks are ext3.

I am curious what issues I might encounter if I updated the OS to 12.1
or 12.2. Specifically:

- Would the disks be compatible? Seems a silly question. But I have
been in situations where lack of compatibility was unexpected.

- After mounting on 12.x, could I expect the disks to work if I
reverted to 11.2?

The disks are data-only. The OS is elsewhere. So the question is not
about reverting the OS. It is really about mounting the disks on 11.2,
12.2, and back to 11.2.

The info for the disks is below:
