Hi all,

Does anyone knows why can't I change the /home dir in to writeable?

Perhaps the root partition was mounted read-only?

I see,

Here is a bit more information. I haven't seen this before. I don't understand. I am logged in as root.

Can anyone help please?

From the output of your mount command, it looks like you are using Solaris. On Solaris, /home is an automount mount point. If you aren't using automount, then mv /etc/auto_master to /etc/auto_master.orig (or a filename of your choice), then bounce automounter. You should now be able to mkdir in /home.
