Status file get's corrupted on restart

[TheMeaningfulEngineer]

I'm doing a long term test to wear out an SD card by writing together with a combination of periodic power outages.

Have set stressdisc as a systemd sctipt that runs on startup:

/usr/bin/stressdisk -statsfile /home/root/status  -logfile /home/root/stress-log-sd -duration 48h0m0s -stats 1m0s -s 500000 cycle /data/senic-hub/logs

I need to delete the /home/root/status every time before running it otherwise I end up with a failed start 2018/06/25 16:26:44 error reading statsfile: EOF

I love it!

Is the status file empty? If so why? Disk Full?

Do you think it is to do with the power outages or something like that?

Can you see if the status file appears empty when it is running?

Don't know why. It does end up being empty while there is still space on the disk.

When it's running it's filling it correctly.

Possibly. Could be the file ends up corrupted or something. Don't know.

I think I might have misunderstood from the docs.

-statsfile string
File to load/store statistics data (default "stressdisk_stats.json")

Does that mean the stats file is mandatory or not?

It allows stressdisk to carry on accumulating stats over restarts. It isn't essential but it will always be used.

If you want not to use it then it could use detect an empty file string and disable the use of the stats file?
