Unable to mount an XFS partiton

Problem: unable to mount an XFS partition in openSuSE 13.1 created under openSuSE 13.2

I have a dual boot system with opensuse 13.2 and 13.1 each on is one different physical drive. I also have a third physical drive with two partitions with XFS.
From openSuSE 13.2 everything works OK and both XFS partitions are mounted and rw without errors.

If I reboot and load openSuSE 13.1 everything works as it should however, I can not mount neither of both xfs partitions. Before, when they had ext4 there was no problem

This is what I did under 13.1
install: xfs, xfsinfo, xfsprogs
reboot

# mount -o rw -t xfs /dev/sdc1 /mnt_tb/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error

Q1. Is XFS under 13.1 compatible with xfs from 13.2?

Q2. am I missing something installing or running XFS.

i don’t know about xfs but there are some packagesin YAST which i hope can give you more info on what is wrong. xfsdump - provides some administrative utilities for xfs. that’s all i can suggest. Good luck!

Thank you for your reply.
I tried to booted also from 3 memory dongles one with OS 13.2, one with OS13.1 and one with OS 12.2
The only one that I was able to mount the XFS partitions was the one with OS 13.2 the other ones produce all the same error. It seems there is no backward compatibility, what is some way make sense. So far openSuSE 13.2 looks very stable and after 2 or 3 more days of testing I may decided to use it, in that case I will not need to access those partitions from 13.1 any more.
Thanks again and Happy Holidays.

Try mount without the “-t …” switch, and with the “-v” one.

No. 13.2 is using newer xfs version which is incompatible.

Are the XFS changes significant enough that I should backup my data from my existing 13.1 XFS
partitions, reformat using 13.2 XFS, than restore my data?

There is no mention of this in the release notes!

What are the differences? Is the format itself so different, or an
update to the tools or kernel would allow sharing?

If the format itself is different, are there tools to convert from a
previous version to the modern version in place, or the only method is
backup/format/restore?

Is this documented somewhere?

Another question: xfsdump/xfsrestore, xfs_copy, are compatible? If not,
you have to use rsync.
