[SOLVED] Zoneminder Disk space issue

[barjac]

As I feared.
OK I guess it's reinstall zm time, but first let's remove the symlinks.
As root (using su not "su -" )

Code: Select all

rm /home/$USER/zm -rf
rm /var/www/html/zm -rf

Now re-install zoneminder

Code: Select all

urpmi --replacepkgs zoneminder

Now run zmsetup and let it create a new mysql database for zoneminder

Code: Select all

zmsetup

Now test it - if it works then use the symlink procedure ONCE and carefully, exactly as I described.

Good luck

[root@localhost cctvadmin]# cd
[root@localhost ~]# su
[root@localhost ~]# systemctl stop zoneminder.service
[root@localhost ~]# mv -T /var/www/html/zm zm
[root@localhost ~]# ln -sf /home/$USER/zm /var/www/html/zm
[root@localhost ~]# systemctl start zoneminder.service
Job failed. See system journal and 'systemctl status' for details.

Doesn't matter, if you run that command as your user, $USER (an environment variable) automatically expands to your username, kinda like a magic placeholder

Just a note here - it is also OK to use this as 'root' using su.
$USER still holds the regular username. (I think of it as a regular user with root privelage)
If "su -" is used then $USER holds "root", which is why I specified su (not "su -" ) in previous posts.

Thanks OK,
I have done all that…
again a couple of times and it now works…
Disk space is still reporting as 31% full though….

[barjac]

Ah good.
I'm suspecting that ZM is reporting the /var usage, it is probably unaware of the symlink to /home, so just ignore the indicator in ZM.
Sadly this also probably means that the filter will not work either, so you will need to set up some other means of monitoring the disk usage.
This is a temporary measure, and you have a LOT of space now, however you need to keep an eye on it.
I will query this upstream out of curiosity.

[freetibet]

Thanks for all your help.
If there is a file edit I can do to make ZM look at the right partition let me know I'm very familiar with nano etc…
It does say I notice in ZM that if there is lack of space then make a sum link as you have suggested to me so probably the fix is quite simple…
Thanks ever so much…

I think my assumption was wrong - here it appears to report the usage of /home - what does df say

Code: Select all

df

How odd.
Here zm is reporting 84% and /home is at 84% according to df.
root is currently at 65% so it's not reporting that.
I can't investigate right now, but I will do some digging on this and let you know.

ZM is now reporting 31 %
so that tallies

[barjac]

No, if yours was reporting like mine, zm would be reporting 2%

Rat found.
That is the normal set-up without symlink.
So let's do this carefully - one step at a time.
We will keep a backup of zm in the / for now, so do this.

Code: Select all

su
cp -R /var/www/html/zm /home/cctvadmin/
mv /var/www/html/zm /var/www/html/zm_orig
ln -sf /home/cctvadmin/zm /var/www/html/zm

OK stop there and give me the output again of

Code: Select all

ls -l /home/cctvadmin/
ls -l /var/www/html/

OK nearly there
Now

Code: Select all

su
chown -R apache:apache /home/cctvadmin/zm
zmrestart


See how that goes.

You are a total hero !

Thanks,

Disk space now reading as 2%….

Horray !!!

[barjac]

Excellent - glad I could help.

One point worth mentioning - avoid using the web interface for starting and stopping ZM - there is a minor bug that I am trying to resolve. Always ssh in and use

Code: Select all

systemctl start zoneminder.service
systemctl stop zoneminder.service
systemctl restart zoneminder.service

as appropriate, as root.
zmrestart is a little script that is handy to do a full server restart - it stops zm, mysql and httpd and then restarts them again in order.

Have fun.

EDIT you can now delete /var/www/html/zm_orig

[freetibet]

Thanks.
I will avoid that…
one problem…
maybe two…
Event viewer .. streaming is fine in eyezm (iPhone app.)... is broken and separately I can't set any interleaving apart from "0"
Don't know if these are related issues...

[barjac]

I have never used eye-zm, but as for the event viewer I have no problems with it using the same symlinked system for testing. My test system is Cauldron - my real server runs mga2.
Did it work before?
I don't recognize the 'interleaving' option that you refer to. What's it for? I never used it.
I would recommend the #zoneminder IRC channel on freenode (or the forum, but IRC is faster) for help with specific problems related to the use of zoneminder.

How do I do this if I am installing a brand new system ?

OK Think I have it now

Can you please be more specific? And if you answer your own question in the same post you asked it in, please:

1. put an EDIT: or something like that in front, so this is obvious for others to see that you made a relevant change in your post
2. if you find a solution to a problem, please give some feedback here, so others can also benefit from that solution.
