Common Users Account

tandem (fsuphysics888) is the general user account.

Anyone wish to have a personal account can be contact Ryan mailto:rtang@fsu.edu, and provides following information

  • full name:
  • username:
  • purpose:

Disks available

Disk Capacity Speed Type Slot Command
/mnt/data_1TB 1 TB 108 MB/s HDD front-1 not recommended
/mnt/data0 48 TB 419 MB/s RAID-0 3x16TB HHD front-10,11,12 recommended

Mount disk remotely

To mount the disk remotely, need the sshfs installed in the local machine. In Debian/Ubuntu

~>sudo apt install sshfs

Create a mount directory in the local machine (say /mnt/data0)

~>sudo mkdir /mnt/data0

Mounting

~>sudo sshfs -o allow_other YYY@pauli.physics.fsu.edu:XXX  /mnt/data0/

where YYY is the user account where XXX is the disk location in the data server.

To mount on startup

edit /etc/fstab

add line

ssh#YYY@pauli.physics.fsu.edu:XXX  /mnt/data0/

User Quota

install the quota program

sudo apt install quota

edit the /etc/fstab

from this

UUID=fc15d3a2-a49f-4974-8216-5949a740ef80 /   ext4    errors=remount-ro 0       1

to this:

UUID=fc15d3a2-a49f-4974-8216-5949a740ef80 /   ext4    errors=remount-ro,usrquota 0       1

remount

sudo mount -o remount /

check the new effect

cat /proc/mounts | grep ' / '
/dev/sdc2 / ext4 rw,relatime,quota,usrquota</spam>,errors=remount-ro,stripe=64 0 0

enable the quota

sudo quotacheck -ugm /

This will create /aquota.user

check

sudo quotaon -v /
/dev/sdc2 [/]: user quotas turned on

Set user quota

use the command 'setquota' to set user quota, in this example 50G is the soft limit, 100G is the hard limit.

sudo setquota -u <User> 50G 100G 0 0 /
  • soft limit: user still can use more than 50G in the next 7 days, after that, this 50G is the hard limit.
  • hard limit: user can never use more than 100G.

quota report

sudo repquota -s /
