The number from /proc/swaps is in KiB. The swapsize= from swapon verbose message is a size calculated from the 'lastpage' field from swap header.
Hi Karel, I'm not worried by a discrepancy of a few pages, but rather by a factor of two. To be on the safe side I just did this: # swapoff -av swapoff on /dev/sda2 # mkswap /dev/sda2 Setting up swapspace version 1, size = 7823648 KiB no label, UUID=ed23d244-73d6-4c8f-b1a2-25659c15e73b # swapon -av swapon on /dev/sda2 swapon: /dev/sda2: found swap v1 signature string for 4 KiB PAGE_SIZE swapon: /dev/sda2: pagesize=4096, swapsize=3716452352, devsize=8011422720 # cat /proc/swaps Filename Type Size Used Priority /dev/sda2 partition 7823644 0 -1 i.e., 'mkswap' and '/proc/swaps' report a swapsize of about 8GiB whereas 'swapon' correctly reports devsize as 8GiB but swapsize as <4GiB.
