Hi. I have SuSE 9.2 on one partition, and 9.1 on another partition. I need some more space now. 9.2 is on the first partition, and 9.1 on the last one. Is it possible to delete the 9.1 and use the space here for 9.2 also ?. Erik Jakobsen

Short answer is yes. Things to consider are: boot loader configuration, fstab settings, having a /home directory in each install. I assume you are using one swap partition.

If I've got this right you have 9.2 on hda1 swap on hda2 and 9.1 on hda3. Assuming that you're giving all of your 9.1 space over to 9.2,and that it's also reiser, you need to add a section to 9.2's fstab mounting it. I'm saying also reiser, but it doesn't have to be, what ever system you've got it formatted under is fine, you want the space. So what room are you running out of? Obviously the big space killer could be the /home directories. I have this on it's own partition so if I upgrade I won't have to lose my data, and if I run out of space, I can put in a larger disk, copy the /home over (fixing the ownerships!!!!!) and keep using disk space. Assuming that you'll turn hda3 over to /home, you'll want to manually mount it, I suggest under either /media or /mnt, see man mount for details on how to. Konqi on over to the partition , you'll more than likely want to do a kdesu konqueror, and remove any and all files (directories are files) copy the directories under your /home over to the new space, and to a safe place on hda1, archive them if you need to. If something goes south we'll have trashed your /home permanently. Here's my fstab entry for my /home partition: /dev/hdc2 /home reiserfs defaults 1 2 and here's the one just above it for my / partition /dev/hdc3 / reiserfs acl,user_xattr 1 1 The disk logic looks like this: hdc3 contains /home as a mount point for /hdc2 which contains any user data in their respective home/username directory. You'll want to right click (in konqi) on the new directories and opt for the properties tab, and fix the ownership section to read the correct user name and group of "users", apply changes to all subfolders and their contents. When I did this under 9.1 the .files didn't change and I had to open a root console and (man) chown Mike:users on the.files in each directory, the .directories too I think. If it tanks, you can of course edit your fstab to delete the mounting of the other partition for your /home, and (man) su to (man) umount the /home partition, and then extract the archived /home back into place. You may need to fix ownerships on the files, but your data should be safe. And remember, it never, ever hurts to have backups. :)

Yes you are quite right about where the 9.2 swap and the 9.1 resides. I use reiser for both OS's. I'm running out of the hda1 partition. Here it's also the /home that can use much more space.
Assuming that you'll turn hda3 over to /home, you'll want to manually mount it, I suggest under either /media or /mnt, see man mount for details on how to. Konqi on over to the partition , you'll more than likely want to do a kdesu konqueror, and remove any and all files (directories are files) copy the directories under your /home over to the new space, and to a safe place on hda1, archive them if you need to. If something goes south we'll have trashed your /home permanently.
I will turn over hda3 to /home. Then its just to mount /dev/hda3 /mnt/home for instance. I have copied both the /home and /etc to a DVD-RW this morning, so that should be safe :-)
Here's my fstab entry for my /home partition: /dev/hdc2 /home reiserfs defaults 1 2 and here's the one just above it for my / partition /dev/hdc3 / reiserfs acl,user_xattr 1 1
Ok.
The disk logic looks like this: hdc3 contains /home as a mount point for /hdc2 which contains any user data in their respective home/username directory. You'll want to right click (in konqi) on the new directories and opt for the properties tab, and fix the ownership section to read the correct user name and group of "users", apply changes to all subfolders and their contents. When I did this under 9.1 the .files didn't change and I had to open a root console and (man) chown Mike:users on the.files in each directory, the .directories too I think.
Ok about Your setup there. And fine about the right click in konqi filemanager. It too can be done with mc (Midnight Commander).
If it tanks, you can of course edit your fstab to delete the mounting of the other partition for your /home, and (man) su to (man) umount the /home partition, and then extract the archived /home back into place. You may need to fix ownerships on the files, but your data should be safe.
Ok Mike. I'll let the job rest for some days, as I'm not too well. My throat is not so good. Think I've catched a flue. Then I'll be back again-
And remember, it never, ever hurts to have backups. :)
I can confirm, that it didn't hurt at all to make the backup on the DVD-RW :-) Erik

You cannot combine hda1 with hda3 unless you change them to lvm. One way you can recover the space used is to re-partition/format. Of course you will need to backup and restore your data. Another way is to use other partitions within your running system such as /usr /opt /home partitions. These come from the space currently being used by hda3. The most efficient way will be to re-partition/format and create swap,/,/home. This will allow the maximum usage of your drive. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 * Only reply to the list please* "The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners." -Ernst Jan Plugge

Hi Ken. I'm somewhat confused now. I want to do what's best. Could You tell me bit more on how to do the last part of Your 2 last lines ?. Erik
