Disks available
| Disk | Capacity | Speed | Type | Slot | Command |
|---|---|---|---|---|---|
| /mnt/data_1TB | 1 TB | 108 MB/s | HDD | front-1 | not 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 /
