I've just installed f37 on a new lenovo x1 carbon.
One thing, the installation didn't setup any swap (other than zswap).
After a bit of reading I found
sudo btrfs filesystem mkswapfile -s 32G /swapfile
But:
sudo swapon -v /swapfile
swapon: /swapfile: found signature [pagesize=4096, signature=swap]
swapon: /swapfile: pagesize=4096, swapsize=1073741824,
devsize=34359738368
Although I created 32G swapfile, only 1G is used.
swapon
NAME TYPE SIZE USED PRIO
/dev/zram0 partition 8G 6.3M 100
/swapfile file 1024M 0B -2
What's wrong?
Something is wrong with how it creates the swap format. Just run
"mkswap /swapfile" and it will be
I totally missed the size discrepancy.
I believe in new btrfs versions, you can use:
# btrfs filesystem mkswapfile swapfile
# swapon swapfile
That's what he did, but the swapfs on the volume had the wrong size. So
a simple run of mkswap fixes that. It's still the same volume with all
the same attributes, just different data.
