moving /home content over to a different disk - how to?
Support, trying to move the content of (almost whole) /home over to a different physical disk. I only have remote access and can only ssh into the machine. Doesnt this get me into trouble of some? locked? files of this user i am sshing with into the users account on this machine? can I su - and then still unmount whole /home and move it over to a different partition on a different disk? what tools do do this best? like rsync? some kind of mirror parameters? any hints appreciated. thanks for having me.

You have to login, actually login, as root, not su, because a) at some point you have to umount /home, and b) because to make a perfect copy nothing should be in use at the moment, meaning no user that has /home should be active. If you can not login as root, create a new user that has a different {HOME} The copy can be done perfectly with rsync. Something like this: OPTIONS="--archive --acls --xattrs --hard-links --sparse \ --stats --human-readable " rsync $OPTIONS \ --exclude=/lost+found --exclude=/dev --exclude=/sys \ --exclude=/proc --exclude=/run \ --exclude=/data/** --exclude=/mnt --exclude=/other \ --exclude=/media --exclude=/var/lib/samba/lock/ \ --exclude=/var/run/ \ / destination -- Cheers / Saludos, Carlos E.

when i SSH into the machine with a normal user account and then simply cd / and then su - ending up in the root user then lsof | grep home there are no entries listed. so I guess i can simply unmount the /home partition and create a new one and mount the new as /home and the old as /home2 and then rsync from /home2 stuff to /home i guess.
use tool said !
Disclaimer:
Warning, the method usermod said is the only correct way
have been experiencing such manual creation without finishing up by
Linux usermod
just ended up in the extremely painful, obscure, subtlest failure for
~5 days without any clue, nor worse, no one has clue, nor can help in
any online media
true, OS seemingly is fine.. but wait some dooms nightmare in
extensive use, as it bite back
definitely it store few flag, bits, or data secretlt to the set /home

Try. My guess is the system will refuse to umount.
and then rsync from /home2 stuff to /home
i guess.

Why doesn't you ssh to root, maybe you do it using an ssh key if you disabled root access using a password. -- fr.gr. member openSUSE Freek de Kruijf
