First NAS, 1 day old and already in trouble

Post by Strobot04 »

Initialized my all new, first-ever NAS yesterday evening: a QNAP TS-473-4G.
At first all went well, some firmware updates (didn’t pay much attention at that time...), initial config and a little browsing the menus.
Now this morning I wanted to explore a bit more, logged on and noticed that the system health displayed a big red cross: NAS fan failure...
Looking further no mensures on system temp, COU nor System fan are displayed at that moment either.
I checked the eventlogs: no record of broken/failing fans.

Rebooting the system helps, for an hour or 2 and then the same issue returns.
Could this be a bug in the very last QTS version, given the fact it’s only out since 28/03...

Activated the Virtualisation station (no VMs created yet however) and installed Jackett, Sonarr and Radarr, Download station.
However neither those have been configured yet neither.
Can I troubleshoot this somehow?

Already did that in the mean time.
I just figured, if someone already had the same problem probably the community would reply sooner than QNAP Helpdesk :-)

Thanks, I noticed as well.
Not sure how to permanently fix it...
Reading the other topic it looks like there is no permanent fix?
Tech support advised to downgrade to 16/03/2019 build...

FYI, this might not permanently fix it, but it does increase the size on tmpfs in /tmp to something more reasonable.
When I get the fan error, it's pretty much always an indicator that tmpfs on/tmp is full. if you SSH to your NAS, run this to check the usage:

df -h

on of the lines you get back should be something like this:
Filesystem Size Used Available Use% Mounted on
tmpfs 64.0M 64.0M 26.8M 100% /tmp

if that's the case, you can expand the size of your tmpfs to something more reasonable without requiring a reboot. The default is apparently 50% of your RAM, but I use 2G just... because.
Increase the size with this:

mount -o remount,size=2G,noatime /tmp

The error should go away shortly after.

Awesome! Thanks for the help! I have a TVS-663 and after upgrading from 4 to 8TB drives, I had issues with it not booting or mounting. Fixed it and upgraded firmware, then had this issue. I think I may have actually had bad fans because I didn't hear them running, so I replaced them and it worked! But soon enough I got the error again even though the fans are running. This worked. Thanks for the help.

So.. I am struggling with this /tmp size on my QNAP which has suddenly been displaying this strange behavior.
Looking at the temporary folder, the total amount doesn't appear to add up to even 2MB even including the hidden files yet this folder seem to be ballooning at the rate of 20MB per day. Not quite sure what is causing this.
Server: TVS-872XT i9 9900 ES, 64GB DDR4 2666MHz, intel X550-T2, Asus RTX3070 Dual OC (On pico PSU), 2x Phison E12 1TB M.2, 4x Micron 5210 7.68TB, 4x WD Purple 4TB

no idea why some tmp folder size makes qnap to show the FAN error, but anyway the fix with increasing tmp memory, even with half of RAM worked in my case too.

Code: Select all

mount -o remount,size=512m,noatime /tmp
Even fixed other problems, with "ram error message" at beginning, and inability to remove files over FileStation 5.
Thank you.
