Low on space in /run.
tmpfs filesystem keeps the entire filesystem (with all it’s files) in virtual memory. All data is stored in memory, which means the data is temporary and will be lost after a reboot. Typically a tmpfs filesystem mounted at /dev/shm as used for the implementation of POSIX shared memory.
The filesystem is automatically created when mounting a filesystem with the type tmpfs via a command such as the following:
$ sudo mount -t tmpfs -o size=10M tmpfs /mnt/mytmpfs
To increase the size, do the following:
- Modify /etc/fstab line to look something like this:
tmpfs /run tmpfs defaults,size=10g 0 0 #OR tmpfs /dev/shm tmpfs defaults,size=10g 0 0
mount -o remount,size=10G /run #OR mount -o remount /dev/shm
df -h (to see the changes)
- Note: Be careful not too increase it too much b/c the system will deadlock since the OOM (Out-Of-Memory) handler can not free up that space.
