Hello Franco,
first, let me say that perhaps this thread should perhaps not be moved into the contribs. SME is supposed to have a base functionality for becoming a NFS client, in order to be able to make backups to an NFS share. This does not work in my case, hence for the poster.
Obviously, others do not encounter such an issue. So, what I am looking here for is some help to be able to just make a backup over NFS to the qnap.
I did encounter references in Centos forums of having to install nfs-utils. And I did install them, albeit with no special SME configuration. This time, trying to mount the NFS share, using the same command as in the original poster just made my mount command halt there. Nothing was output'ed. No mount was done as well.
In Franco's reference, I can see that the following were executed after nfs-utils got installed:
config setprop portmap status enabled
service portmap start
Should I do them as well? Is it "safe" for production servers?
