Yesterday i was installing a TSM Server for our company. The db2 installer complain about the /tmp size.
The installer need 2,5GB and my /tmp has only 2 GB.
I create a “disk” using dd command with 4GB on a partition with lots of space.
dd if=/dev/zero of=/usr/tmpDSK bs=1024k count=4096
mkfs -t ext3 /usr/tmpDSK
mount -o loop,exec,nosuid,rw /usr/tmpDSK /tmp
After the db2 installation i umount the /tmp and mount it back using fstab -a
