Hey guys, I’m having a problem with my unraid server. I added another cache drive last night after finally getting my other one to show back up and booted the server up and it was stuck starting the array for a while. I shut it down and removed the second cache drive and booted back up, now the GUI won’t load. I can ping the IP but even on the console, the GUI doesn’t load. Any ideas on how to fix this?

 

EDIT: the gui finally loaded, but is starting the array, its been sitting there for a bit. I do see the cache drive is completely full. Do I need to clear it out?

There's probably a ton of errors relating to the full drive (I'm assuming it's btrfs)  You can always post your diagnostics.

I'll post the diagnostics here shortly, as soon as it lets me get to it. When the GUI is working, it is really slow, and keeps going from responsive to unresponsive. Give me a few mins and I'll post it. Thanks!

 

I was downloading the diagnostics (well running it) and now the GUI isn't loading at all. What should I try to do? I don't want to mess it up any more than I already have

Look on the flash drive in the logs directory.  There should be a diagnostics zip file generated from today.  Upload it.  If not, then when you regain access from the command prompt,

diagnostics

And a new set will get saved in the logs folder.

Here are the logs from yesterday. I tried the diagnostics command from the terminal and it gave me this error: "Starting diagnostics collection.... mkdir: cannot create directory '/boot/logs' : Input/output error. 

Luckily it did have the logs from yesterday, which is when this happened.

Reseat the cabling to the cache drive (power and sata).  It dropped offline in the those diagnostics.

 

The can't create /boot/logs implies that either you pulled the flash drive out or it also dropped offline.  Reseat it (if it's a continuing problem, try a different port, ideally USB2)

 

Either one of these will cause the issues you're seeing.  

 

Ultimately your only recourse is a power down.  Try at the terminal

 

powerdown

 

To see if it can gracefully shut itself off.  Otherwise do a hard shutdown.

Ok, I’ll give that a try. I did reseat the connections last night and moved the usb to other port. But I’ll try it again and see what happens. Will report back shortly. Thanks!

I reseated the connections and booted back up. I’m in the terminal window and typed diagnostics and it’s starting collection but has been sitting there for about 15 mins or so. Should I close the window?

yup

It isn't saving the diagnostics for some reason. No clue what to do now..

 

From the webGUI, diagnostics *should* pop up a window that gives the current command that it's running.  What is it?

This is where it gets stuck at. 

Your best solution is to restart the server in Maintenance mode, then run the file system checks https://wiki.unraid.net/Check_Disk_Filesystems against the cache drive

Ok, is maintenance mode the same as safe mode? I try to reboot from the GUI and it doesn't reboot. It just hangs. So I have to do a hard reboot.

No.  Once the GUI is loaded you have to stop the array and then restart in Maintenance Mode. (There's a checkbox).  If you can't do that, then on the flash drive edit /config/disk.cfg on the flash drive and change startArray="yes" to instead be "no"

Thanks. I booted into Safe Mode while I was waiting on your reply and I was able to run the diagnostics. Here it is. Earlier, I took the cache drive out and put it in my windows machine, but couldn't see any files, which it isn't formatted for windows, so I knew I probably wouldn't be able to see anything, but figured I would try. I was going to try and delete come stuff off the cache drive and free up some space. Right now, there is zero bytes free on it.

So I rebooted out of Safe Mode back into normal mode and the cache drive is unmountable it says. But it shows the drive is healthy.

This is what the "check" shows

 

I tried to mount the drive as an unassigned device, but I get this:

i took a backup of my unraid server back on 7/20 and i installed a new drive and am trying to get my dockers/appdata back, if i do a restore, will it restore the apps/dockers back without me having to reconfigure everything?

Edited July 31, 20213 yr by Parzival_PRO

Restore appdata and recreate docker.img, then Previous Apps on the Apps page will let you reinstall any and all dockers exactly as they were using the templates saved on flash when you installed them before.
