I'm running the linux distro on my server.When i want to verify the size of the disk, i'm issuing this commnand to get the output.
df -h
But it does not produce ANY output.Strangely enough when i'm issuing other command such as fdisk -l or du -h it can show output normally.
Does anyone now why is this happening?Thanks.
edit:
here is the output of cat /etc/fstab
none /dev/pts devpts rw 0 0
and this is for mount command
none on /dev/pts type devpts (rw)
none on /proc/sys/fs/binfmt_misc tpe binfmt_misc (rw)
edit(2):
here is the output of cat /proc/mounts
/dev/vzfs / vzfs rw,relatime,usrquota,grpquota 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
none /dev/tmpfs rw,relatime 0 0
none /dev/pts devpts rw,relatime 0 0
none /proc/sys/fs/binfmt_misc binfmt_msc rw,relatime 0 0
