Hi!

OS - Armbian bionic

Board - Orange pi one

I dont understand where goes 20-25% of 512mb ram.

 

18MB goes to video and wlan share. OK...

 

root@OrangePiPBX:~# zramctl
NAME       ALGORITHM DISKSIZE  DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram1 lzo          98.2M 19.8M 10.2M   11M       4 [SWAP]
/dev/zram0                50M 17.7M  2.5M  2.9M       4 /var/log

 

Now we see - 150MB go's to swap and small partition for "logs".

 

root@OrangePiPBX:~# free
                         total        used        free      shared      buff/cache      available
Mem:         502932      242376       26380   20008      234176      232640
Swap:        100584       21504       79080
Here we see ram now in total(used and free) - 250MB

250+150 = 400

 

And now... can someone answer me - where is my 100MB ram?

 

Here is config for ZRAM:

nano /etc/default/armbian-zram-config

ENABLED=true

ZRAM_PERCENTAGE=20

 

Here is config for Ram-log:

nano /etc/default/armbian-ramlog

ENABLED=true
SIZE=50M
USE_RSYNC=true

 

root@OrangePiPBX:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            177M     0  177M   0% /dev
tmpfs            50M  5.4M   44M  11% /run
/dev/mmcblk0p1  7.1G  3.8G  3.3G  54% /
tmpfs           246M     0  246M   0% /dev/shm
tmpfs           5.0M   12K  5.0M   1% /run/lock
tmpfs           246M     0  246M   0% /sys/fs/cgroup
tmpfs           246M  380K  246M   1% /tmp
/dev/zram0       49M   18M   28M  40% /var/log
tmpfs            50M     0   50M   0% /run/user/0
 

That's all.

Maybe i am doing something wrong?

Providing logs with 

armbianmonitor -u

 significantly raises chances that someone is looking at it.

Probably not. Kernel is changing, features are added, something that we might not want gets in by mistake. I suspect 3D driver reservations or just something, which could be seen from the logs. Or not and a deep investigation is needed.

I think i have a problem with some default settings of Zram.

Like i see in doc's - Zram and swap is "preninstalled". And from first run i have only 50% of RAM

One more interesting thing!

nano /etc/default/armbian-zram-config

ENABLED=true

#ZRAM_PERCENTAGE=20

i comment ZRAM_PERCENTAGE=20

and what we see now:

root@OrangePiPBX:~# swapon --show
NAME       TYPE        SIZE USED PRIO
/dev/zram1 partition 245.6M   0B    5

 

root@OrangePiPBX:~# zramctl

Up.

Can anyone help me?

Same issue here on Bullseye beta on N2+.    If a new thread is wanted just say so.

Armbian 20.11.0-trunk.9 Bullseye with Linux 5.8.12-meson64

 

df -h shows no /dev/zram(x)    zramctl shows nothing    same for fdisk -l     swap.target is active loaded.

sudo nano /etc/default/armbian-zram-config  ENABLED=TRUE  is only param set here.

 

Per Igor request:   armbianmonitor -u    at       http://ix.io/2z9h

 

All I got.  Any ideas to get this running ?

 

EDIT:  May be this  wasn't run at some point      sudo systemctl start  armbian-zram-config

 

per this thread https://forum.armbian.com/topic/15268-zswap-or-zram

 

I'll call this fixed after a few tweaks to the armbian-zram-config file.
