Rock64 / Débian : Ajouter un disque dur externe

48 x served & 7 x viewed

Je viens de prendre un disque dur externe car j’ai pas trop confiance dans les cartes SD ( désolé Michel).

Etape 1 : Le formatage, pour cela il faut fdisk !

rock64@rock64:~$ cat /etc/debian_version 
9.9

rock64@rock64:~$ sudo whereis fdisk
fdisk: /sbin/fdisk /usr/share/man/man8/fdisk.8.gz

rock64@rock64:~$ dpkg -S /sbin/fdisk
util-linux: /sbin/fdisk

rock64@rock64:~$ sudo fdisk -l               
Disk /dev/ram0: 4 MiB, 4194304 bytes, 8192 sectors

Disk /dev/sda: 1.8 TiB, 2000398933504 bytes, 3907029167 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos

Device     Boot Start        End    Sectors  Size Id Type
/dev/sda1  *       64 3907024128 3907024065  1.8T  7 HPFS/NTFS/exFAT

rock64@rock64:~$ sudo mkfs.ext3 /dev/sda1
mke2fs 1.43.4 (31-Jan-2017)
/dev/sda1 contains a ntfs file system labelled 'Seagate Portable Drive'
Proceed anyway? (y,N) y
Creating filesystem with 488378008 4k blocks and 122101760 inodes
Filesystem UUID: 42a1cde2-2269-4582-b4a0-2bb6272b0990
Superblock backups stored on blocks: 
	32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

	102400000, 214990848

Allocating group tables: done       

A noter qu’en cas de crash durant le formatage, je conseille alors :

rock64@rock64:~$ sudo mkfs -t ext4 /dev/sda1

Et si la connexion n’est pas stable pendant le formatage :

rock64@rock64:~$ sudo apt-get install screen
...
rock64@rock64:~$ sudo screen -dmS "format"  mkfs -t ext4 /dev/sda1
...

Etape 2 : Préparation du montage sur l’OS :

rock64@rock64:~$ sudo mkdir /disk1

rock64@rock64:~$ sudo mount /dev/sda1 /disk1

rock64@rock64:~$ df -H

Filesystem      Size  Used Avail Use% Mounted on
udev            2.1G     0  2.1G   0% /dev
tmpfs           412M  5.6M  406M   2% /run
/dev/mmcblk1p7   63G   41G   20G  68% /

tmpfs           5.3M  4.1k  5.3M   1% /run/lock
tmpfs           2.1G     0  2.1G   0% /sys/fs/cgroup
/dev/mmcblk1p6  118M  1.1M  117M   1% /boot/efi
tmpfs           412M     0  412M   0% /run/user/1000
/dev/sda1       2.0T   80M  1.9T   1% /disk1

Etape 3 : Modification du fstab :

rock64@rock64:~$ sudo vi /etc/fstab 

Etape 3 bis: On peut aussi utiliser les labels:

rock64@rock64:~$ sudo e2label /dev/sda1 nextcloud
rock64@rock64:~$ sudo vi /etc/fstab 
rock64@rock64:~$ sudo cat /etc/fstab 
LABEL=boot /boot/efi vfat defaults,sync 0 0
LABEL=nextcloud /disk1 ext4 defaults 1 1

ATTENTION, il faut tester le fichier /etc/fstab AVANT le reboot … sinon c’est LA MORT

rock64@rock64:~$ sudo mount -a /etc/fstab 

Voir même un petit text de copie :

rock64@rock64:~$ sudo cp -r /var/www/html/nextcloud/ /disk1/.
