To see if a drive is mounted use something like this:
if mount | grep "/mnt/storage" >> /dev/null
echo "Drive is mounted"
echo "Drive is not mounted"
You could also consider using the SSH option to rsync:
Setup a SSH identity on the system where you'll be running the rsync:
ssh-keygen -b 1024 -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx root at myth
Then copy the /root/.ssh/id_rsa.pub to the remote
cat /root/.ssh/id_rsa.pub | ssh root at REMOTESYSTEM "cat
Now you should be able to ssh from the one server to the other, as those
users without a password.
rsync -av --delete --exclude=nice_names /mythtv/recordings
