I wonder if I could script something that could run in single user mode when it reboots, but 1. how do I tell it to reboot in ginle user mode, via SSH? 2. how do I tell the server to login by itself, i.e. don't need someone to type in the root password @ the console, then check to make sure it's in single user mode? >From here could be as simple as unmouting /var, running lvresize +2GB /dev/LVM/var etc Has anyone done anything like this before, with success? i.e. do you have a working procedure / script to share with me? I won't be able to test the process, if it fails then I'm stuck > -- > Kind Regards > Rudi Ahlers > SoftDux > > Website: http://www.SoftDux.com > Technical Blog: http://Blog.SoftDux.com > Office: 087 805 9573 > Cell: 082 554 7532 > -------------- next part -------------- An HTML attachment was scrubbed...
