Ubuntu üzerinde ikincil bir disk ekledikten sonra bu diski kalıcı olarak bir klasöre mount etmek için aşağıdaki yolları izleyebilirsiniz.

Disklerimizi kontrol ediyoruz.

lsblk

Ekleyeceğimiz disk sda diski. Öncelikle partition oluşturuyoruz

fdisk /dev/sda
Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x2ecefee3.

Command (m for help): p
Disk /dev/sda: 800 GiB, 858993459200 bytes, 1677721600 sectors
Disk model: Virtual Disk    
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x2ecefee3

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p

Bu kısımda daha önce bu diskte partition olmadığı için default 1 olarak geliyor. Enter tuşuna basıp geçiyoruz. Default 1 olarak alıyor.

Partition number (1-4, default 1):

Tekrar ENTER

First sector (2048-1677721599, default 2048):

Tekrar ENTER

Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-1677721599, default 1677721599): 
Created a new partition 1 of type 'Linux' and of size 800 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

Tekrar lsblk yapıyoruz ve partition adını kontrol ediyoruz.

İlgili kısmı ext4 olarak ayarlıyoruz

Şimdi disk UUID öğreniyoruz

sudo blkid

Ben bu diski /mnt/longhorn dizinine mount edeceğim. Bu nedenle şimdi klasörü oluşturuyorum

mkdir -p /mnt/longhorn

Şimdi kalıcı olarak boottan sonra mount olabilmesi için fstab’a ekleyelim. UUID adresinizi kopyalamayı unutmayın

nano /etc/fstab

En alta ekliyoruz

UUID=47447a2a-01cd-4017-90ac-7997f08adc3e /mnt/longhorn ext4 defaults 0 2

Kaydedip çıkıyoruz. Ardından mount ediyoruz.

mount -a
root@worker02:~# cd /mnt/longhorn/
root@worker02:/mnt/longhorn# ls -la
total 24
drwxr-xr-x 3 root root  4096 Feb 26 12:15 .
drwxr-xr-x 3 root root  4096 Feb 26 12:19 ..
drwx------ 2 root root 16384 Feb 26 12:15 lost+found

Booom!
