[CentOS] mounted NFS does not show in df -h

Hey guys,

 This is kind of odd, so I wanted to do a sanity check.

 I mounted an NFS share like so:

[root at web1:~] #mount -t nfs nfs1.jokefire.com:/home /mnt/home

Seemed to go ok. Then I took a look at the output of df -h and didn't see
it!


[root at web1:~] #df -h
Filesystem                  Size  Used Avail Use% Mounted on
/dev/vda                     40G   24G   14G  64% /
devtmpfs                    996M     0  996M   0% /dev
tmpfs                      1001M     0 1001M   0% /dev/shm
tmpfs                      1001M  101M  901M  11% /run
tmpfs                      1001M     0 1001M   0% /sys/fs/cgroup
s3fs                        256T     0  256T   0% /backup/cassandradb
s3fs                        256T     0  256T   0% /backup/mysql
nfs1.jokefire.com:/var/www   20G  3.1G   16G  17% /var/www


Yet, when I do a df -h on the directory I mounted the NFS share on, I see
that it's mounted via NFS as expected:

[root at web1:~] #df -h /mnt/home
Filesystem               Size  Used Avail Use% Mounted on
nfs1.jokefire.com:/home   20G  3.1G   16G  17% /mnt/home

So, what do you think could be happening? Why is it that I can't see the
output I'm expecting just by going df -h???

Thanks!!
Tim
