NV4216E-AI Freezing/Unreponsive
Posted: Sun May 22, 2022 9:31 am
So I'm looking for a little advice/suggestions on what to try next. My NV4216E-AI has frozen randomly 3 times. When it gets to that state I can still ping it but the web interface won't load, the image on the screen is frozen, button presses do nothing, remote API commands do not work (tried rebooting via API) so I have no choice but to flick the power switch.
I had a 2TB and 4TB HDD installed but recently switched the 2TB for an 8TB (all WD Purples). My first thought was that when it filled the new drive it got confused as some of the data was split between the old a new drive in an inconsistent manner (I was using a single HDD group). It has always been set to automatically delete when full. I thought in order to clear things up I could reformat both drives *using the NVR, so I did that and I ran fine again until the new drive was full. (that's as far as I can notice when checking after hard rebooting) So my next attempt involved formatting and splitting the drives into 2 HDD Groups and balanced the load of cameras based on the size of the drives so they would hold approximately the same number of days... it then froze again. I have since switched back to a single HDD group since it didn't seem to help
The unfortunate thing is I had made a few changes to my system within a couple days, the new 8TB HD, swapped out an IP2M-843EB for a IP8M-2496E, changed the recording frequency for a few cameras that were on MD only to 24HR (now that I had more space) and also changed an HDMI cable because our TV was moved. Also a different surge protector is now powering the NVR. So with all these changes happening close together it's hard to think for sure its the drive.
The HDD test/detect all shows as fine and detects no bad sectors on either drive. Last night when it happened I finally I thought to look at the logs and saw nothing overly suspicious. There was a "shutdown" command listed for the time I cycled power which had the approximate time I thought it froze in bracket in the info field, unfortunately it was late and I didn't think to export it or save it and now I can't bring back yesterdays logs. I also noticed quite of few connections and disconnections from my Home Assistant instance so I disabled the software in case the extra connections were causing the issue (but doubtful as that has been like that for months with no issues). Also last night I decided to stop all recording and format them with recording stopped so I wasn't trying to save data while formatting to give me a fresh start. So now I wait to see what happens when the drives fill up again. I believe last night both drives were full and it should have been deleting old data (it was on 2HDD groups evenly filling both drives at same time). Aside from putting the old 2TB drive back in and waiting for everything to fill up again I'm not sure what else to try.
I'm hoping maybe someone has had similar issues before and could give me some suggestions.
