I can remember when my 30 MB hard drive seemed like a bottomless pit of storage space. Now I see 500 million times that much space (1.5 PB) is available on this supercomputer disk array. This is my first time seeing a "P" in the df -H output: $ df -HTP | perl -pe 's/ +/\t/g ; s/Mounted\ton/Mounted on/' | align Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_root ext4 17G 9.5G 6.3G 61% / tmpfs tmpfs 13G 17k 13G 1% /dev/shm /dev/sda1 ext3 508M 136M 346M 29% /boot /dev/mapper/vg_root-lv_tmp ext4 6.2G 147M 5.8G 3% /tmp /dev/mapper/vg_root-lv_var ext4 66G 868M 62G 2% /var panfs://10.32.8.10:global panfs 1.5P 903T 544T 63% /panfs buzzard:/zprod/project/kumarv nfs 53T 50T 3.4T 94% /project/kumarv 10.32.8.31:/soft/el6 nfs 3.1T 1.2T 1.9T 40% /nfs/soft-el6 10.32.8.31:/adm/suacct nfs 7.1T 3.5T 3.6T 50% /adm/suacct 10.32.8.22:/intel nfs 281G 230G 51G 83% /nfs/soft-intel 10.32.8.12:/ nfs 1.5P 903T 544T 63% /nfs/roc buzzard:/zprod/project/expeditions nfs 27T 25T 1.6T 95% /project/expeditions buzzard:/zprod/project/limko nfs 28T 5.6T 22T 21% /project/limko buzzard:/zprod/project/sadowsky nfs 5.5T 4.8T 728G 87% /project/sadowsky Mike
