Flash-Plugin UUID what?

Eddy2909 · 29. September 2019

Hi community
I just set up omv on a rpi4 and tried to do the setups written from flash plugin:

Code

Fstab (/etc/fstab) muss manuell geändert werden. Folgenden Schritte ändern:


Login als root lokal oder über ssh
Führen Sie den folgenden Befehl aus: nano /etc/fstab
Fügen Sie Dateizugriffszeiten und Ordnerzugriffszeiten als root Optionen ein. Siehe vorher und nach Beispieleinträge:
ANFANG:
UUID=ccd327d4-a1ed-4fd2-b356-3b492c6f6c34 / ext4 errors=remount-ro 0 1
NACH:
UUID=ccd327d4-a1ed-4fd2-b356-3b492c6f6c34 / ext4 noatime,nodiratime,errors=remount-ro 0 1
Auskommentieren der Swap-Partition. Siehe vorher und nach Beispieleinträge (nur ein # am Anfang der Zeile eintragen):
ANFANG:
UUID=a3c989d8-e12b-41d3-b021-098155d6b21b none swap sw 0 0
NACH:
#UUID=a3c989d8-e12b-41d3-b021-098155d6b21b none swap sw 0 0
STRG-o Speichern
STRG-x Verlassen
Neu starten

My Problem: I cant find any string like this cryptic one UUID=ccd327d4-a1ed-4fd2-b356-3b492c6f6c34 / ext4 errors=remount-ro 0 1

my output of fstab is:

Code

proc            /proc           proc    defaults          0       0
/dev/mmcblk0p1  /boot           vfat    defaults          0       2
/dev/mmcblk0p2  /               ext4    defaults,noatime,commit=600  0       1
/var/swap none swap sw 0 0
tmpfs           /tmp            tmpfs   defaults        0       0
# >>> [openmediavault]
/dev/disk/by-label/SGW521A1LS /srv/dev-disk-by-label-SGW521A1LS ext4 defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl 0 2
# <<< [openmediavault]

thanks for some hints what exactly to do

I always assumed that the Pi images had this done by default and required no user input.

I'll tag @Adoby because I'm sure he has a couple of Pi's.

If you used the official image from sourceforge you don't have to do anything. Your fstab looks like you did.

The modifications are optional anyway.

Yes - I used the official one. But the point is: I can't acivate the plugin or is it activated like this? (see attached)

The plugin is activated from install. You don't need to do anything.

The modification you are supposed to do is adding noatime and commit. And as you can see, on line 3, they are already on the fstab line.

noatime avoids having the time of every access to every file to be written to the SD card.

commit=600 means that stored writes to the SD card are flushed and written every 10 minutes. Otherwise the writes would be flushed immediately. This means that several small writes can be written as one write.

From the readme file for the RPi images: "openmediavault-flashmemory plugin preinstalled to reduce wear on SD card."

Yes, it is enabled like this. When it is installed, it is enabled.

You can check by using lsblk from CLI. You will see some output with "zram" which shows you that the plugin is active.
