With all this memory work I have been doing I finally noticed that free was reporting 24GB swap:
# free total used free shared buff/cache available Mem: 15625916 7018872 6765700 109108 1841344 8162532 Swap: 25165816 0 25165816
Thing is I only have 16GB in my swap partition:
# fdisk -l /dev/sda Disk /dev/sda: 465.76 GiB, 500107862016 bytes, 976773168 sectors Disk model: WDC WDBNCE5000PN Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xa3fd40f9

OK. What is happening. I remember Ed's comment about him using zram, so I did some digging and find:
# swapon --show NAME TYPE SIZE USED PRIO /dev/sda3 partition 16G 0B -2 /dev/zram0 partition 8G 0B 100
Um, I did not know I set up zram? How did that happen. Is zram now part of the basic Fedora install?
It has been a while my using zram. How do I disable it for now? With 16GB real memory and 16GB real swap partition, I want to see how things are working...
thanks
