Problem with improper shutdown

[timelyfiasco]

Hi, I have been running zoneminder for a few days and it was working without orange or red warning in the log for hours. But we had a black out last night, and I think when zoneminder is not exited properly it says it has no permission to write in the events folder.
I run ubuntu and added to fstab my samba drive to var/cache/events. To remedy this, I ran chown again and I lost the cant write to folder error.
Then upon checking the events in the homepage, it went to zero. But the files are still in the hard drive. I did nothing but chown and mysqlcheck database.
So never mind that, but I got another error again in the log which says, can someone help me?
My other question is, is it normal for me to encounter problem after an improper shutdown? Thank you.

I think something happened to the database and mysql when the sudden shutdown occurred. Can you stop zoneminder then stop Apache and mysql. Restart mysql then apache and ZM. ALSO make sure the system clock and time/date is properly set! this can also cause what you are experiencing.

Hi rockedge, thank you for trying to help. It is not really a serious concern since I was able to fix it right away. I was just curious if zoneminder is able to start again after an improper shutdown. But upon further consideration, I was able to run zoneminder on boot after pulling the plug on my rasp pi several times. So I guess my question is not clear as I cant get particular with what happened.

Please don't pull the plug on your rasp-pi, you may well permanently/semi-permanently trash the SD card, leading to all sorts of unreliability and ultimately, death
