Filesystem event does not exist in database

Post by stevensr2002 »

Version: 1.30.4
Pretty sure I installed through EPEL / Yum, but it has been a while
Centos 6.9

Hello,

I believe we have had some kind of hard drive issue. We've had to restart zoneminder service a few times, but today I noticed after doing so that the events all reset to 0. Nothing for the total events... It is a Dell server, and I do not currently have an iDRAC installed - otherwise I would have checked disk health.

It appears that it is deleting the files because they no longer exist in the database.

I have 2 drives I believe are mirrored for the OS, and 4 drives are setup for storage.

In fstab, see the following (removed most of the characters in UUID - not sure if that was useful or not in terms of security):

Code: Select all

UUID=be9c /                       ext4    defaults        1 1
UUID=fe92 /boot                   ext4    defaults        1 2
UUID=b16c /home                   ext4    defaults        1 2
UUID=b17d swap                    swap    defaults        0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
/home/zoneminder/events /var/lib/zoneminder/events none defaults,bind 0 2
/home/zoneminder/images /var/lib/zoneminder/images none defaults,bind 0 2

Seeing a bunch of entries like the following:

I'm wondering if the database was rebuilt (maybe the location was unmounted) with the hard drive issue. I'm guessing there's no way to recover from this, as it appears to be actually deleting the files. We originally were at 94% disk utilization, and it has gone all the way down to 21% and still going.

I'm planning on getting an iDRAC installed, and adding a solarwinds account so it can do more than poll ICMP. But is there anything I can do or check on my end to confirm my thoughts? How about a way to prevent this specific issue? It looks like I'll be installing CentOS 7 and the newest version if I've lost everything here.
