* Write sync status to HDD_LOG/log2ram.log. - Store sync status directly in the HDD log, to make sure we know about it if something fails. This won't help if the HDD_LOG variable is borked, but it'll help with everything else. - Made sync a function to avoid repeating five lines three times. - log2ram now requires (cp or rsync) and tee, mount, umount. * Split sync into syncFromDisk and syncToDisk. - After restarting, I realized that I had combined both types of sync into one line, when the syncing failed. This fixes that bug. * Exclude log2ram.log from rsync so rsync doesn't delete it on sync. |

Log2Ram
Like ramlog for systemd (on debian 8 jessie for example).
Usefull for Raspberry for not writing all the time on the SD card. You need it because your SD card don't want to suffer anymore !
The script log2ram can work on every linux system. So you can use it with your own daemon manager if you don't have systemd.
Log2Ram is based on transient log for Systemd here : A transient /var/log
Install
git clone https://github.com/azlux/log2ram.git
cd log2ram
chmod +x install.sh
sudo ./install.sh
into /usr/local/bin/log2ram
- You can change the SIZE variable if necessary
- If you prefer to use rsync, you can set the USE_RSYNC variable to
true
Customize
services :
If you open the file /etc/systemd/system/log2ram.service , you will see a line starting by Before=, you can list here the services who need to start after log2ram. You will need to change this line when a service start too fast and stop running because log2ram mount a ram folder where it has start to write log.
For example, If you use apache instead of nginx, add apache2.service into this line.
variables :
Into the file log2ram (or /usr/local/bin/log2ram if you have already installed it), there are two variables into the script : SIZE=40M and USE_RSYNC=false
The first variable define the size the log folder will reserve into the RAM.
The second variable can be set to true if you prefer "rsync" than "cp".
###It is working ? You can now check the mount folder in ram with
df -h
mount
######Now, muffins for everyone !
