| |
I unlinked a swapfile without realizing I was still swapping on it. Now my /proc/swaps looks like this: Filename Type Size Used Priority /var/tmp/EXP/cache/swap/1\040(deleted) file 1288644 1448 -1 /var/tmp/EXP/cache/swap/2\040(deleted) file 1433368 0 -2
AFAICT, there's nothing I can pass to swapoff(2) that will make the kernel let go of them. If that's the case, please consider this a feature request for a way to do this. Now I'm going to have to reboot before I can mkfs that partition.
If kswapd0 had a fd open on the swap files, swapoff /proc/$PID/fd/3 could possibly work. But it looks like the files are open but with no user-space accessable file descriptors to them. Which makes sense, except for this case.
thanks, and happy hacking,
