Hi Jeanette, no, it isn't, you're most likely fooled by the confusing output of df. Assuming you're still using fstab, then as long as there isn't an explicit uncommented entry in fstab, tmpfs takes around half of the available memory. In your case just one time 1,7G for tmpfs as a whole. I suspect you have 4 GiB of RAM and a [rocketmouse@archlinux ~]$ df -h|head -1;df -h|grep tmpfs Filesystem Size Used Avail Use% Mounted on tmpfs 1.9G 4.0K 1.9G 1% /dev/shm tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup tmpfs 1.9G 8.0K 1.9G 1% /tmp tmpfs 371M 32K 371M 1% /run/user/1000 [rocketmouse@archlinux ~]$ grep tmpfs /etc/fstab #tmpfs /tmp tmpfs nodev,nosuid,size=3G 0 0 [rocketmouse@archlinux ~]$ hwinfo --memory | grep Size Memory Size: 3 GB + 512 MB [rocketmouse@archlinux ~]$ uname -m x86_64 An issue I experience since a very long time is, that I'm missing 256 MiB, since the frame buffer size should be 256 MiB, due to BIOS settings, so I expect 3 GiB + 768 MiB. I guess the missing 256 MiB aren't reserved for the kernel, since the output of hwinfo years ago didn't made such arbitrary calculations.
None of that is part of my /etc/fstab, so the next question would be:
Btw. it's possible to directly use systemd to mount, without keeping an fstab. Regards, Ralf
