What is in /tmp and /usr/tmp?

3.4 MB files and 4 KB files

What is in /lost+found?

Nothing.

oh, and have you run fsck to see what state the file system is in and do some clean up.

You should see about leaning /tmp then.

There are many reasons why having /tmp on a separate FS (including some security ones that claim to have been overcome, but I'm a bit paranoid there) is a good idea. Of course if you have a lot of memory then /tmp (or some part of it) can be a tmpfs

It's possible to have /tmp cleared out automagically at boot. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not a good idea. Probably self defeating. Some applications make heavy use of tmp, and even heavier use when there is not sufficient memory to hold stuff in memory. As posted in another reply k3b is one of these. It will create multi gigabyte iso images in tmp and then NOT ERASE them!! Opensuse default partitioning scheme should probably be re-thought, to either move /tmp to its own partition, or make / (root) considerably bigger than the default recommended currently. Users installing for the first time are not in a position to guess future requirements when stuff is scattered all over in /tmp /usr/tmp, and some portions of what is in these so called temp directories is now expected to survive a reboot!!

I am not an expert on such matters, but I cannot understand what the temp files have to do with my problem. They only occupy a very small fraction of the root, a few MB in 20 GB.

Also, the logs seem not to be the source of trouble.

sudo du -h /var/log root's password: 88K /var/log/ConsoleKit 4.0K /var/log/krb5 54M /var/log/journal/41ef233e76e7528b304b79b700000697 54M /var/log/journal 4.0K /var/log/samba 4.0K /var/log/hp 15M /var/log/YaST2 1.4M /var/log/zypp 4.0K /var/log/news 1.6M /var/log/cups 102M /var/log

It seems that the safest thing to do is to uninstall the older version of Mathematica. If I do this, I will recover 3 GB. That helps, but unfortunately, that is not much, and I would like to preserve the old version... Probably the best thing to do would be to set a larger partition for root when I installed opensuse. Is there a safe and easy way to enlarge the root partition?

Thanks

You can only resize a partition if you have spare space on the drive, or if you can shrink some other partition. Gpartd can do this. But in your case you may find it simpler to move /usr to its own partition. It seems to me that there was some noise on this list with systemD making this more complicated than it was in the past (it was never drop dead easy, unless, as mentioned you are sitting on a bunch of unallocated space). -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes... it does.

If you have a initrd (which is default and almost everyone** has), then /usr is mounted via logic in initrd prior to the systemd even starting from what I understand.

--- **"everyone"=those who don't care as much about speed. The systemd reference pages suggest *NOT* using initrd for faster boot. Who knows, maybe suse will support faster boots in the future.

Probably not if you are using primary partitions and they are back-to-back. As Patrick says, if you use LVM then you have a lot more flexibility. What you could do is add another drive, format that (possibly as LVM showing foresight) and migrate /var or something to it. I have unloaded a lot of the root fs. As people have pointed out, since initrd mounts /usr you don't need to have that as part of the rootFS. I've put the huge libraries I have for perl and Ruby into separate partitions so /usr could be in a smaller one. Using LVM you can make smaller specialized partitions for managing in different ways. Networked workstations can share a /usr/share/ on a server. I Depending on your disk layout you *might* be able to migrate /home to another drive , remove that partition from the main drive and expand the root FS into the space you've just freed up. Drives are cheap :-) A 1T from Tiger is about $70. Slight more at BestBuy.
