2 years ago The script allows you to specify custom mount options for that folder, like you use in fstab or when mounting manually. See the default config file:
#############################
#folder2ram main config file#
#############################
#
#PROTIP: to make /var/lock or /tmp available as ram filesystems,
# it is preferable to set the variables RAMTMP, RAMLOCK
# in /etc/default/tmpfs.
#
#TYPE: options available are "tmpfs" (for a ram folder)
#
#OPTIONS: mount option (will be passed as options to mount), if left blank "defaults" will be used
#
#TIMEOUT=2m #write here the timeout limit for folder2ram service activity
# #(the time specified here must cover the mount/unmount time of all folders)
# #if you are using systemd init, when you change this value you must run
# #folder2ram -enablesystemd again to update the systemd service units with the new value
#
#IMPORTANT: use 2 Tabs to separate "type" from "mount point" from "options", the script needs them to read correctly the configuration.
#
#<type> <mount point> <options>
#tmpfs /var/logtmpfs mount options allow you to define the size of the tmpfs for that mount https://www.man7.org/linux/man-pages/man5/tmpfs.5.html
so if you write this in the options
#<type> <mount point> <options>
tmpfs /var/log size=1gthe script will pass those options to the mount command. This example should limit that mount point to 1 gigabyte of size.
If you don't define mount options, the default mount options are setting the limit to half your RAM. If half your ram is 56 GB, you have a lot of RAM.
Hello,
I wanted to suggest a rather simple option to specify the size of each mount in RAM since folder2ram currently allocates what looks like 56G for /var/log which seems way overkill and could fill the RAM up fast on an accidental write of tons of data.
