Mounting Drives¶
This server has at least one USB hard drive that remains constantly connected. We need this drive to mount on system startup, for this, we'll need to set up the fstab.
Getting Drive UUIDs¶
In order to get the UUIDs of the drive in question, it is necessary to plug them in. Once this is done, execute the following:
lsblk -o NAME,FSTYPE,UUID
This will give an output similar to the following:
NAME FSTYPE UUID
sda
├─sda1 vfat 7811-FFBE
└─sda2 ext4 3c98de9f-dc43-4e8d-85aa-767475ea957b
sdb ext4 418987da-2351-11e9-aec8-b8975ad7798b
If you cannot tell which drive is which, you can also run the following:
sudo fdisk -l
Which will give out an output similar to the following:
Disk /dev/sdb: 1.82 TiB, 2000398934016 bytes, 3907029168 sectors
Disk model: Hitachi HUA72302
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/sda: 223.57 GiB, 240057409536 bytes, 468862128 sectors
Disk model: CT240BX500SSD1
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 18C45280-7C95-4D8C-8033-81277842D6FF
Device Start End Sectors Size Type
/dev/sda1 2048 2203647 2201600 1G EFI System
/dev/sda2 2203648 468858879 466655232 222.5G Linux filesystem
Notice the Device value for each, reference it with the output from the previous command, and you'll now be able to tell the identifier of the partitions you need.
Preparing the Folders¶
We'll mount the hard drives in /media, for this we'll create the folders like so:
sudo mkdir /media/my_drive
You may also change the ownership on these folders if it causes any problem.
sudo chown -R 1000:1000 /media/my_drive
Modifying fstab¶
Danger
Make sure to have physical access to the server in case editing this file breaks your installation. If your file is not correct, the system will boot in safe-mode with SSH disabled.
We'll modify the /etc/fstab file.
sudo nano /etc/fstab
And we'll add a new line for each hard drive with the following structure:
UUID=$UUID $DIR $FORMAT defaults 0 0
In our case, we'll add the following lines:
/dev/disk/by-uuid/98e05af0-fa9c-4952-a8d6-e09280626835 /media/my_drive ext4 defaults 0 0
Finally, reboot the server. The drive should now be automatically mounted.
