/var/log is 100% full - how to move to HDD?

[Schlotze83!]

Gents,

 

installed Armbian Bullseye successfully to my Banana Pi M2 Berry. In second step i moved the OS to my attached 2,5 WD RED Sata Harddrive. This was easily possible with the command "sudo nand-sata-install".

 

But now, i see that my /var/log is full, because its located in ZRAM.

 

root@BananaPiM2Berry:/etc/systemd/system# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            431M     0  431M   0% /dev
tmpfs           100M   11M   90M  11% /run
/dev/sda1       687G  1,3G  651G   1% /
tmpfs           500M     0  500M   0% /dev/shm
tmpfs           5,0M  4,0K  5,0M   1% /run/lock
tmpfs           500M     0  500M   0% /tmp
/dev/mmcblk0p1  1,7G  1,3G  385M  77% /media/mmcboot
/dev/zram1       49M   48M     0 100% /var/log
tmpfs           100M     0  100M   0% /run/user/1000

 

As you can see i hve more than 650 GB avail in my root parttiion on /dev/sda1. But how can i setup /var/log to wirte on /dev/sda1 ?

 

i believed to find it in /etc/fstab, but its not there.

# <file system>                                 <mount point>   <type>  <options>                                                       <dump>  <pass>
tmpfs                                           /tmp            tmpfs   defaults,nosuid                                                 0       0

/media/mmcboot/boot                             /boot           none    bind                                                            0       0
UUID=614c4feb-de66-4b2c-a046-ce72aaf2e600       /               ext4    defaults,noatime,commit=600,errors=remount-ro,x-gvfs-hide       0       1

 

Right now, the device is unuseable, i cant even install system updates, since no more logs can be written. Since i have so much storage avail on my HDD, i wonder how to move /var/log there...

if the whole OS is no longer on a SD card you can disable ramlog in /etc/default/armbian-ramlog.

Hi Werner,

 

so, when i disable ramlog in the config and then reboot the /var/log will be automatically on the HDD somewhere under /

 

is my understanding correct? - Thanks!

Logs should be written directly to /var/log without the man-in-the-middle ramdisk mounted there, yes.

如果整个操作系统不再位于 SD 卡上，您可以在 /etc/default/armbian-ramlog 中禁用 ramlog

thanks.😄
