Thanks for the report. Please run the experiment again using strace to find the result of the statfs(2) calls made by the program to the kernel. strace -e statfs df -m /mnt/ramdisk/dav/ /mnt/dav/ This will report what information the df command is getting and therefore will explain why df is printing what it is printing. > normal behaviour (n22_uml is the UML sytem, n22_tun the host) : > n22_uml ~ # df /mnt/nfs/n22_tmp > Filesystem 1K-blocks Used Available Use% Mounted on > n22_tun:/tmp 14011712 10646784 2653184 81% /mnt/nfs/n22_tmp > > Now I stop nfs at n22_tun: > n22 ~ # /etc/init.d/nfs stop > ... > Ang got finally under UML: > n22_uml ~ # df /mnt/nfs/n22_tmp > Filesystem 1K-blocks Used Available Use% Mounted on > n22_tun:/tmp 77371252437321868667518976 0 > 77371252437321868667518976 0% /mnt/nfs/n22_tmp Please do the same thing here too. strace -e statfs df /mnt/nfs/n22_tmp > Here the exports - file from the host: > n22 ~ # cat /etc/exports > # /etc/exports: NFS file systems being exported.

It can lead to silent data corruption. But I don't think it is related to your current problem.
