But where do I find this value? I can't see it on my df:
Filesystem Type Size Used Avail Use% Mounted on
/dev/root ext4 9.5G 3.3G 5.8G 37% /
devtmpfs devtmpfs 3.7G 0 3.7G 0% /dev
tmpfs tmpfs 3.7G 148K 3.7G 1% /dev/shm
tmpfs tmpfs 3.7G 604K 3.7G 1% /run
tmpfs tmpfs 3.7G 0 3.7G 0% /sys/fs/cgroup
tmpfs tmpfs 3.7G 20K 3.7G 1% /tmp
/dev/sda1 ext4 477M 80M 369M 18% /boot
/dev/sda5 ext4 969M 2.3M 900M 1% /usr/local
/dev/sda6 ext4 205G 70G 125G 36% /home
/dev/sda7 ext4 3.8G 527M 3.1G 15% /var
However, free yields:
Mem: 7732364 1253864 6478500 2544 37264
334996 -/+ buffers/cache: 881604 6850760
Swap: 16383996 0 16383996
and I did set it up using anaconda.
Many thanks again!
