Hello!
Thank you for this lovely tool. Just spotted this behaviour that does not seem to be desired.
Here's my situation, a Linux server with two mounts: / and /var/www/virtualmin:
root@web01:/# df -h | grep -vE 'snap|run|udev|tmpfs'
Filesystem Size Used Avail Use% Mounted on
/dev/nvme0n1p1 39G 16G 24G 40% /
/dev/nvme1n1 30G 25G 4.7G 85% /var/www/virtualmin
When I use vmtouch against /, it indicates total pages ~ 16G which aligns with filesystem usage on the / mount - so looks like vmtouch skips the mount in /var/www/virtualmin:
root@web01:/# vmtouch / 2>&1 | grep -v WARNING
Files: 544678
Directories: 47977
Resident Pages: 209724/4307663 819M/16G 4.87%
Elapsed: 47.997 seconds
But when I execute it against all files in / (skipping some), it indicates total pages as 39GB which more or less aligns with total filesystem usage on both / and /var/www/virtualmin, so in this variant it includes the mount:
root@web01:/# vmtouch $(ls -d /* | grep -vE 'dev|sys|proc|snap|run') 2>&1 | grep -v WARNING
Files: 819215
Directories: 103000
Resident Pages: 305073/10413686 1G/39G 2.93%
Elapsed: 45.924 seconds
Is this expected? My linux version: 5.4.0-1103-aws.
