I started 2 UML instanves and mounted from one (trinity) a remote share
from the other UML machine (n22stab4). FWIW it is always the same
exported directory "/mnt/ramdisk", but mounted w/ different fs types :
NFS v[234] and hostfs.


I'm wondering about the output of the command df -m.

The client gives 3072 MB :

trinity ~ # df -m
Filesystem            1M-blocks  Used Available Use% Mounted on
rootfs                     1846  1268       467  74% /

tmpfs                       300     0       300   0% /mnt/ramdisk
n22stab4:                  3072  1538      1535  51% /mnt/hostfs
n22stab4:                   300     0       300   0% /mnt/nfsv4
n22stab4:/mnt/ramdisk       300     1       300   1% /mnt/nfsv2
n22stab4:/mnt/ramdisk       300     0       300   0% /mnt/nfsv3



whereas the server says 1846 MB:


tfoerste@n22 ~ $ ssh root@n22stab4
n22stab4 ~ # df -m
Filesystem     1M-blocks  Used Available Use% Mounted on
rootfs              1846  1538       197  89% /
/dev/root           1846  1538       197  89% /
devtmpfs             501     0       501   0% /dev
tmpfs                501     1       501   1% /run
shm                  501     0       501   0% /dev/shm
cgroup_root           10     0        10   0% /sys/fs/cgroup
tmpfs                300     1       300   1% /mnt/ramdisk

which correlates to the image size of 2 GiBi :

tfoerste@n22 ~ $ ls -l ~/virtual/uml/
total 5836716
-rw-r--r-- 1 tfoerste users 2000000000 Sep  3 19:53 n22stab4
-rw-r--r-- 1 tfoerste users 2000000000 Sep  3 19:11 n22unst4
-rw-r--r-- 1 tfoerste users 2000000000 Sep  3 19:53 trinity
