How can I see the total usage of the whole disks.


Usually, I use
Code:
df -lh
. but it only shows one disk 160G. But actually, we have 32 disks and how can I see the total usage of the whole disks in parallel computer. Thanks

Try
Code:
df -h

lsblk

fdisk -l
If those don't work, how are the disks mounted eg RAID?
HW RAID only shows what the OS sees, not the actual HW.
You'd need HW specific tools to see further down.

Thank you, I try the
Code:
df -h
in each node, I found strange that in the login node it cannot show any other usage while when I turn into the node1, it shows like;

Filesystem Size Used Avail Use% Mounted on
/dev/sda3 143G 13G 123G 10% /
udev 9.0G 108K 9.0G 1% /dev
/dev/sda1 99M 21M 73M 23% /boot
node17:/public 459G 165G 271G 38% /public
node17:/users 466G 419G 25G 95% /users
node17:/data2 459G 305G 131G 70% /data2
node17:/home 455G 293G 139G 68% /home

Anyway, you solve my problems,but I don't know why. Thank you for your help.
