-----Ursprüngliche Nachricht----- Von: Ted Byers Gesendet: Mi. 02.12.2015 21:02 An: openSuSE List , Betreff: [opensuse] What is the procedure to create a new install of OpenSuse on a new SSD, and preserve the data on the existing drive?

OK, I have two machines that are presently running OpenSuse 13.2. In both cases, problems arose when the root partition filled up.

I have a new SSD to install in each. What I would like to do is install OpenSuse fresh onto the SSD, and have the existing drive in each machine serve for /home, and that in a way that preserves whatever data I have on the drive.

Actually installing the SSD isn't that much of a problem, but I am uncertain as to what I will see when the install program detects two drives, and what to tell it to do with them. What exactly would I tell it to do, so this all works? And then, after I finish that install, Can I remove everything from the existing drive except for the home directory, and how do I tell Suse that home is there? Assuming I have a complete install onto the new ssd, what directories can I safely move to the old drive which will reduce the likelihood that root will run out of space?

Thanks

Ted

-----Ursprüngliche Nachricht Ende----- Hi Ted. There are many reasons why a root partition can run out of space. Some are normal, some not.

First consideration (before doing anything else): if the data in /home is valuable, what I suppose, as you want to safe it, please consider doing a backup. An easy program for doing it in 13.2 is luckybackup from the repos (using rsync proto). Second: what was the size of the root partition that did ran out of space? What was the filesystem you did use? And did you check whether you do not have a huge logfile accumulating or that the settings of the /temp are wrong and you run out of space because of useless clutter? If you use a ssd: use btrfs. You asked what could you place on the hdd that is going to hold /home. Provided that it is a very big disk, with a lot of space, you could create two partitions and mount one for home and one for /var. This is especially true if you run virtualization with libvirt/quemu because of course every OS that you going to install will take exactly the space that you attribute (and that can be much). If you use virtualbox with variable size virtual partitions the situation is only marginally better. So /var could be a good idea. Hold in mind that snapshots can accumulate in btrfs (I think this was a particular problem in 13.2 at the beginning but I am not sure about). What you are going to see: you may install without the home disk installed and just uncheck "propose a separte home". Then after install, you branch the disk, you see the old home and you mount it as /home. This is easy done if you use a user "test" during the install. Then, if you attribute the old home and mount it as /home you can then, after reboot, create a new user with the same name then the preexisting ones. You will be asked if you want to take ownership as a /home with this name already does exist. You say yes. Once you log into the user created you will be at home. User test (or whatever name you gave) can now be deleted. You can then, in the partitioner, eliminate the partitions that are old root and swap. Create a big partition with btrfs and attribute /var. I would advice to leave swap in the ssd because of its speed. All depends on what is the reason for root being filled. The biggest ssd is full if you have a gigantic log or jounal accumulating. Or a cluttered filling temp. By all means: do a backup. Good luck. PS. make a copy of .mozilla and of kwallet (in case the conversion fails, at least you have the passwords). But I forgot, wise man did a backup. --- Alle Postfächer an einem Ort.
