Check /etc/default/armbian-zram-whatever file. Don't remember the exact name
 

I realised, that my OrangePI Plus 2E doing the logrotate of /var/log.hdd and not /var/log dir
I'm using:
 
root@orangepiplus2e:~# lsb_release -a Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster root@orangepiplus2e:~# uname -r 5.3.13-sunxi In my dir /etc/logrotate.d/ I realised that in every file standing: /var/log.hdd/.... as a path for logrotate even if I change to /var/log/... everytime when I restart my box.
Now if I understand correctly the ram part is named: /var/log/... what can I see from:
root@orangepiplus2e:~# df -h Filesystem Size Used Avail Use% Mounted on udev 939M 0 939M 0% /dev tmpfs 202M 556K 201M 1% /run /dev/mmcblk0p1 15G 4.6G 9.4G 33% / tmpfs 1007M 0 1007M 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 1007M 0 1007M 0% /sys/fs/cgroup tmpfs 1007M 44K 1006M 1% /tmp mrtg2ram 10M 3.4M 6.7M 34% /var/www/mrtg /dev/zram0 340M 7.1M 308M 3% /var/log tmpfs 202M 0 202M 0% /run/user/0 Here I see that /dev/zram0 is mounted as /var/log. Size I changed in /etc/default/armbian-ramlog.
I inspected and found the file: /usr/lib/armbian/armbian-hardware-optimization is responsable for changing path from /var/log to /var/log/hdd
 
Now what I do not understand is if-else-fi part of function prepare_board() from this file.
CheckDevice=$(for i in /var/log /var / ; do findmnt -n -o SOURCE $i && break ; done) # adjust logrotate configs if [[ "${CheckDevice}" == "/dev/zram0" || "${CheckDevice}" == "armbian-ramlog" ]]; then for ConfigFile in /etc/logrotate.d/* ; do sed -i -e "s/\/log\//\/log.hdd\//g" "${ConfigFile}"; done sed -i "s/\/log\//\/log.hdd\//g" /etc/logrotate.conf else for ConfigFile in /etc/logrotate.d/* ; do sed -i -e "s/\/log.hdd\//\/log\//g" "${ConfigFile}"; done sed -i "s/\/log.hdd\//\/log\//g" /etc/logrotate.conf fi First line checking is it exist the path /dev/zram0
Secod line if yes then rename in every file from /etc/logrotate.d/ pattern /var/log to /var/log.hdd
....
If not do reverse...
 
Why is implemented this?
If all my logs going to /var/log and it's raising what is the logic, if the armbian-ramlog enabled, to rotate /var/log.hdd and not the /var/log ?
Who will then rotate /var/log if it will be full let it say after 12h or 96h?
This problem I had not on Armbian with kernel v3.4.xxx (Jessie), that after every restart the content of files in logrotate.d was renamed.
Because I'm not able to understand the logic bihind this I have opinion as it is reversed this if-else-fi part.
 
Would be someone so kind to explain me the logic?
Thx
