Could this have something to do with it?

What are the permissions of /mnt and /mnt/vdb?

On CentOS they'd both need to have the eXecute bit set for all users else Apache can't see or traverse the directories below them, so maybe it's the same with Ubuntu and other distros?

I would have thought that it should still see the disk size though.

In my mind, it's about detecting changes larger than the things you're looking for and using those large-scale changes to prevent other zones triggering.

I found this useful: ZoneMinder's Zoning System for Dummies

I found that making a fairly large Preclusive zone and detecting changes (but not blobs) that affect a significant percentage of that zone stopped most shadow- and cloud- and sunlight-induced false alarms.

I get this too, using ZM 1.32.2 on CentOS 7.

11 GB out of 218 GB is about 5%, which is coincidentally the default amount of reserved space for ext2/3/4 file systems. You can change the value using tune2fs -m X /dev/sdYZ where X is the percentage of reserved space desired (e.g. 1, 0.5, etc.) and YZ is the partition identifier (e.g. 'c1' for /de...

Have you tried using MediaInfo to inspect a stream saved using FFMpeg and -codec copy? That might provide some clues.

Can you set up an NTP service on the ZM machine and have the cameras get their time from that?

Quality 6 I don't know what the range available is on that camera, but most of the cameras and video software I've come across use lower numbers for better quality - On my current cheapo-Chinese things the scale runs from 1 through 6, with 6 being lowest quality. Maybe trying a lower number is wort...

My situation is similar but not exactly the same (I'm simply using a directory under /home rather than a dedicated disk, and I'm moving the entire /var/lib/zoneminder directory) and I found that I also had to change the Default Storage Path at Options -> Storage in the ZoneMinder console. I also had...

Maximum Alarm Area = "If more than this much of the zone changes, don't raise an alarm"

It can be set in pixels or percent.

I get a SQL error if I leave the 'Extend Alarm Frame Count' box empty when creating a Preclusive zone. Not sure where to report bugs so I thought I'd drop it here. web_php - 15231 ERR - SQL-ERR 'SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'ExtendAlarmFrames' cannot be null', stateme...
