Univention Bugzilla – Bug 37781
Separate partitions (/var, /tmp, /usr, ..) and /var space
Last modified: 2015-08-06 18:08:26 CEST
The installation fails if I use a 10 GB hard drive, install the whole software and use the auto partition separation into /var /tmp/ usr /home etc. root@master312:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_ucs-root 3.7G 348M 3.2G 10% / /dev/sda1 457M 48M 385M 11% /boot /dev/mapper/vg_ucs-home 980M 1.3M 912M 1% /home /dev/mapper/vg_ucs-tmp 101M 25M 69M 26% /tmp /dev/mapper/vg_ucs-usr 3.7G 3.1G 397M 89% /usr /dev/mapper/vg_ucs-var 579M 537M 88K 100% /var tmpfs 1006M 0 1006M 0% /dev none 202M 14M 188M 7% /run root@master312:~# Either we should increase the minimum size of /var or we should remove the partition separation from the installation menu.

The Debian package information contains the "Installed-Size" [KiB] <https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Installed-Size> information, which is required by the package. This information by itself is not enough when multiple partitions are used, as there is no detailed information about the required space per /opt, /usr, /var, and /.
I did an installation on a 10 GB hard disk with separated /home /var /usr /boot with all components installed. The installation was successful and afterwards the following disk space was used: # LANG=C df -h -T -x tmpfs -x devtmpfs -x rootfs Filesystem Type Size Used Avail Use% Mounted on /dev/disk/by-uuid/ca961… ext4 1.9G 391M 1.4G 22% / /dev/sda9 ext4 2.3G 154M 2.0G 8% /home /dev/sda8 ext4 218M 2.1M 201M 2% /tmp /dev/sda5 ext4 3.7G 3.2G 381M 90% /usr /dev/sda6 ext4 1.3G 689M 516M 58% /var
r14570 | d-i/partman: Minimum part size Reduce minimum swap size to 96 MiB as 100% with 10 GiB RAM is too much. The "atomic" recipe uses min="100% of RAM" for swap, which is too much if RAM=10 GiB but HD<16 GiB. Changes min=96 MiB as this is used by "home" and "multi" as well.

We should also increase the space for / if /home is on a separate partition. A tester reported he used a 320 GB hard disk and the auto partition created 302,6GB for /home 4,1GB for / 12,8GB for swap
