What sort of load were you putting on the system, also what is your
configuration :
memory
disks used for XFS
cpus
Could you also run
xfs_growfs -n /xxx
where /xxx is the mount point of the filesystem in question. This will
dump out some filesystem parameters.
I would like to be able to duplicate this crash, or at least establish
if it is a setup which we know has problems.
The vnode crash is being worked on, all I have managed to do so far is
make it harder to hit. It is basically top of the list at the moment.
The repair problem looks related to an already reported problem.
Thanks for trying XFS!
