>Description:
Hi,

I'm currently migrating a linux system to bsd and did not succeed in mounting xfs partitions under bsd.
The xfs partition was created under linux several years ago and runs fine under linux. If I try to mount it under bsd I get the following output:

1st try:
root at magni:~# mount -t xfs -r /dev/ad8s1 /mnt/Lagerhaus 
mount: /dev/ad8s1 : Invalid argument

2nd try:
root at magni:~# mount -t xfs -r /dev/ad8s1 /mnt/Lagerhaus
mount: /dev/ad8s1 : Operation not permitted

Using "-o ro" instead of "-r" makes no difference.
In kernel log the following two lines appear on each mount attempt:

fsname '/dev/ad8s1' logname '' rtname ''
flags 0x200000 sunit 0 swidth 0 logbufs -1 logbufsize -1

Running xfs_check /dev/ad8s1 reports no problems.

Any ideas?

Regards,

Jens
