But that is for the file name only, not the target_dir, and they will all go into target_dir location regardless of how you define the generated file name.
And if there is lots of motion, you will get lots of files.
My idea is I could log into the boatPC using remote desktop and look at the AVI and jpg files remotely from home.
I am 20 minutes from marina by car.
Code:
############################################################
# Live Stream Server
############################################################
# The mini-http server listens to this port for requests (default: 0 = disabled)
stream_port 8081

It's probably running out of inodes in that directory, so new files can't be created.
For info, if the OP is using ext2/3/4 then there is no per-directory inode limit since the number of inodes available for use is a global number.
In saying that, if OP is using ext2/3, then there is a limit of 32k *hard links* (e.g. subdirectories) per directory. For ext4, with the dir_nlink feature enabled, which is the default, there is no such limit. If dir_nlink isn't enabled in ext4, then the figure is 64k.
If the dir_index feature is enabled in ext4, then there is a practical limit based on the maximum depth of the htree structure but we would be talking several million directory entries before problems could arise. Normally you would run into performance limitations long before running into this limit.
Perhaps the OP could paste here the initial metadata (not the block group info) from sudo dumpe2fs /dev/sdax (replacing sdax with the relevant filesystem's device) so that we can examine the filesystem structure and inode availability.
I am not at the boatPC to post from there, but I setup as ext4 using the linux installer.
I need to reboot ubuntu, will edit this.
I could not even post a fraction of the terminal, and the terminal runs off....
What to do ?
I solved the pid file issue, so it nows runs without sudo.
Since I had been starting using sudo, all my test folders were owned by root in my home and I was trying to write to those folders.
When I started fresh, it worked.
And I solved the date time by mv the folder as a new name and recreate the original folder and it works.
I setup a script to run every hour, just to see it working using cron -e
my script will start moton, but I can't stop motion yet. If I use 'pkill motion', the script terminates at that line.
But not stopping motion seems to be ok so far, has not been interfering with things..

Don't worry about it. If you've solved the problem of the program stopping working then there's no pressing need to look at your inode situation.
Anyway, mea culpa, I should have specified to you that it was easiest to use the -h option to only print the superblock info i.e. sudo dumpe2fs -h /dev/sdax

Yes, think it will be ok at boat which is mint 18 with ext4
here is ubuntu ext4 at home.

If this is the PC with which you had the motion problem then it isn't connected to lack of inodes on this data drive (to which I assume you're saving the generated images). In fact, bizarrely, you have very few in actual use. I assume you deleted almost everything off the drive but have kept a few very large files (maybe archives)?

This drive is the one at home and was not having trouble with motion files.
I am not even sure it is my OS partition. I have 3 drives, I think in this PC.
Yes, just looked at gparted, sdc5 is my user /home partition, not sda3

Not much use, I'm afraid if this isn't the "boat PC". I thought we were examining the relevant drive on the machine on which you had the problem, not a completely different computer!
Out of interest, why did you think it would be of use running diagnostics on a machine where you hadn't experienced the original problem? I don't get it.

Point being, I did nothing special installing Mint 18 with ext4, so do you think it would have a different file system configuration versus Ubuntu 16.04 Ext4?
Anyhow, the boat is way over there, and I am way over here.
I am thinking of using Chrome remote desktop to remotely control the boatPC.
they may help you --
off the top of my head without watching these vids. I'd do this with your script.
Code:
#!/bin/bash
echo "foo"
#pkill motion
Log_File="/where/ever/you/want/it/LogFile.log"
Images1=/home/scott/testmotion/motion-files
Move_Images_to="/home/scott/testmotion/motion-files"
Test_folder=/home/scott/testmotion/motion-files
#put a counter in it to split up your images dir a little more?
Runcount=1
while [[ true ]]
do
#inside loop to get updated with each pass.
Date="$(date +%F-%H:%M:%S)"
#only increment it in the first line so it matches in
# second line.
mkdir -pv "$Move_Images_to-$((Runcount++))-$Date" >> $Log_File
mv -v "$Images1" "$Move_Images_to-$Runcount-$Date" >> $Log_File
mkdir -pv "$Test_folder" >> $Log_File
#shut down motion how ever it gets shut down
#and remove PID
rm /path/to/PID
sleep 60
or whatever time one wants.
then call to restart after sleep.
you dir are already set up for it.
#restart motion
motion -c /path/to/config/file
done
I got a say whoever wrote this didn't think far enough past his nose to think someone would want to start, stop, and maybe even pause this application and code it to allow it to be done. making this process a lot easier.
note that is not a completely working script, just an Idea ...
this just shows how the log file looks, maybe redundant or over kill in what you are doing but might come in handy.
Code:
userx%slackwhere ⚡ ~ ⚡> mkdir -vp my/test/dir/ > testLog
userx%slackwhere ⚡ ~ ⚡> cat testLog
mkdir: created directory 'my'
mkdir: created directory 'my/test'
mkdir: created directory 'my/test/dir/'
userx%slackwhere ⚡ ~ ⚡> cd my
userx%slackwhere ⚡ my ⚡> ls
test
userx%slackwhere ⚡ my ⚡> cd test
userx%slackwhere ⚡ test ⚡> ls
dir
userx%slackwhere ⚡ test ⚡>
MOD: hours later I see its been marked solved, so .. goody -- now you can be a spy master.
