Thanks for the quick reply - yes, that helped. So, is that something I should report to the Xen folks? These "other filesystems" I can unmount with no BUG :-) I just noted something else, but completely unrelated to that barrier stuff: # ls -ld /mnt/d* dr-xr-xr-x 1 root root 0 Jan 1 1970 /mnt/d1 drwxr-xr-x 3 root root 4096 May 5 21:45 /mnt/d2 # grep mnt/d /proc/mounts /dev/xvdb /mnt/d1 btrfs rw,relatime,nobarrier 0 0 /dev/xvdc /mnt/d2 ext3 rw,relatime,errors=continue,data=writeback 0 0 How comes btrfs thinks it has been created at the beginning of time?
