I have a virtual server with ubuntu 10.04.4 LTS and plesk (preinstalled by hosting company).
Now i have seen that the buffers/cache are always empty. Current uptime is 22 days. free and htop shows the same values.
root@server:/root# free -m total used free shared buffers cached Mem: 4096 540 3555 0 0 0 -/+ buffers/cache: 540 3555 Swap: 4096 0 4096
root@server:/root# mount /dev/vzfs on / type reiserfs (rw,usrquota,grpquota) proc on /proc type proc (rw,relatime) sysfs on /sys type sysfs (rw,relatime) none on /dev/pts type devpts (rw,relatime)
I have searched stackexchange/google but found nothing. How can I enable filecache or is this not possible cause of vzfs and all is good?!
