Give static name to USB

[merkelbeek]

Hi All,

I have a raspberry pi Running with plex, Now i connect an external hardrive to it where my movies are stored on.
But everytime i unplug the device and replug it get's another name
first it was sda, the second time i plug it was sdb and nog its sdc. How can i make it static? so that it always is sdc?

Use the PARTUUID.

Discover that with sudo blkid when the drive is plugged in.

It's my first day of linux lol
can you give more detailts about that?

[DougieLawson]

Open an LXterminal window run
sudo blkid

And you'll get something that looks like:

Code: Select all

pi@mercury:~ $ sudo blkid
/dev/mmcblk0p1: UUID="8C10-A11F" TYPE="vfat" PARTUUID="f9965871-01"
/dev/mmcblk0p2: UUID="9a7608bd-5bff-4dfc-ac1d-63a956744162" TYPE="ext4" PARTUUID="f9965871-02"
/dev/sda1: SEC_TYPE="msdos" LABEL_FATBOOT="RECOVERY" LABEL="RECOVERY" UUID="6B9B-AF3E" TYPE="vfat" PARTUUID="314d5e11-01"
/dev/sda5: LABEL="root" UUID="39eb752a-27fb-4e4e-b38c-a1040200ec23" TYPE="ext4" PARTUUID="314d5e11-05"
/dev/sda6: LABEL="rootfs" UUID="26992cbf-74a1-4b6d-84eb-802b70f9fd9c" TYPE="ext4" PARTUUID="314d5e11-06"
/dev/mmcblk0: PTUUID="f9965871" PTTYPE="dos"
pi@mercury:~ $

So in my example to mount /dev/sda6 I'll use PARTUUID="314d5e11-06"

sudo mount PARTUUID=314d5e11-06 /media and /dev/sda6 will get mounted.

Code: Select all

pi@mercury:~ $ sudo mount PARTUUID=314d5e11-06 /media
pi@mercury:~ $ mount | grep media
/dev/sda6 on /media type ext4 (rw,relatime)
pi@mercury:~ $
