August 29, 20223 yr Hi all, Noticed Plex and Nextcloud were down today while at work. Returning home I have been able to briefly access a partially loaded Dashboard screen, but then clicking over to Main has resulted in nothing loading at all now. I did notice a bunch of notiifications flash by, one of which was for a toasty HDD. First time this has happened in 18 months of blissful stability so not sure what the best approach is. Reboot or something else?
August 29, 20223 yr Author Many thanks for the respnse. I wasn't able to access them as I couldn't access the GUI (unless I'm missing something obvious which is always a possibility!). Ended up rebooting and things have come back to life so far. Diagnostics post reboot are attached although not sure if that will help you much? themagiceye-diagnostics-20220829-1931.zip
August 29, 20223 yr Community Expert Solution You can also get the diags in the console, see the link above for how to, but if all is well now it doesn't matter, get them if it happens again.
August 29, 20223 yr Community Expert Looks like you may be using more of rootfs than expected. rootfs is the space in RAM for the OS files, but any path that isn't mounted storage is a path in rootfs. If you fill rootfs the OS will behave erratically since it has no room to work in. A likely suspect would be a host path of one of your containers.

Hi @trurl have just noticed your response here - many thanks. A few weeks have now passed and I've had another out of memory error last night and this morning a server that appears to have hung. Unfortunately didn't see you post until after I reset the machine today so cannot get Diagnostics via the terminal. The reboot doesn't seem to have helped in this case as I am still unable to access the GUI. Have tried installing Putty on a local windows machine as per instructions and then SSH into the server but I get the following error: Network error: connection timed out. There is no dialog about the host key as the wiki suggests on a first time login. Kinda freaking out so hoping you might have some suggestions on what to try next. Thanks in advance Edit: Have just plugged the server directly into a monitor and tried another reboot. UnRaid doesn't seem to be booting at all - I just end up in the BIOS screen.

September 22, 20223 yr Community Expert Make sure your BIOS is trying to boot from your Unraid flash drive. Do you have a current flash backup?
September 22, 20223 yr Author 3 hours ago, trurl said: Booting UEFI or CSM (legacy)? BIOS has been set to boot in legacy mode since first setting up the server. Seems the USB flash drive isn't being picked up by the BIOS - it's not listed in the boot priorities as an option. I do have a flash backup via MyServers that says its from last night at a time when the server was definitely still working. Should I restore this onto a new USB drive or try other things frst?

I could see the drive on a windows machine, although when I pugged it in Windows wanted to correct errors on the drive. I let it do this, and it then went through its process and declared no errors were found. From there I accessed the drive as normal. I then tried booting from another USB port on the server and hey presto it's back. I have attached diagnostics, but not sure if they will tell you much. I have also stopped both Tdarr docker containers for now as I have noticed they seem to push the CPU usage to 100% at times, altough not sure of memory. If any container is causing an issue, my gut says this will be it. Any advice on how to troubleshoot from here? themagiceye-diagnostics-20220923-1131.zip

September 26, 20223 yr Author On 9/23/2022 at 12:06 PM, trurl said: You can use this command to check if usage is growing df -h / So after a few days of checking on this usage has grown only 1% from 23 to 24%. I have also checked the paths on all of my containers and they are all pointing to the appropriate shares on the array - nothing directed towards the flash drive. I thought I'd check in to see if you had any final thoughts? And also to say thanks again for your help!

The flash is mounted at /boot The command given was to check space at / which is the root. 5 hours ago, nametaken_thisonetoo said: they are all pointing to the appropriate shares on the array Problems sometimes occur when there are typos, like capitalization errors.

Could you elaorate for a relatively unskilled Unraider?
