I recently tried to change one of my cache pool disks and I must have done something wrong because now I have no interface. I can boot in GUI mode, safe or regular makes no difference, I can access the cli, midnight commander and Htop but I'm new to all of this and don't know my way around them. firefox will open, and I can connect to internet, I can ping google.com and 8.8.8.8.

 

i tried creating new usb boot drive from the unraid connect backup but that was the same thing. I guess the back up must have been made after the problem started.

 

Installed unraid 7.0.1 onto my usb, and started fresh. all my data was there and the cache/pool drives, including the one i am trying to remove. I transferred the community apps and dockerman folders to the flash once my server was up and running and got all my dockers working again as before.

 

everything was working well and then I tried removing the pool drive again and the problem happened again.

 

This time I used the guide from the unraid site and followed these instructions

 

Remove a disk from a pool

There have been times when users have indicated they would like to remove a disk from a pool they have set up while keeping all the data intact. This cannot be done from the Unraid GUI but is easy enough to do from the command line in a console session.

Note: You need to maintain the minimum number of devices for the profile in use, i.e., you can remove a device from a 3+ device raid1 pool but you can't remove one from a 2 device raid1 pool (unless it's converted to a single profile first), also make sure the remaining devices have enough space for the current used pool space, or the removal will fail.

With the array running type on the console:

btrfs device remove /dev/sdX1 /mnt/cache

Replace X with the correct letter for the drive you want to remove from the system as shown on the Main tab (don't forget the 1 after it).

 

 

the array froze up when i tried stopping the pool and I had to do an unclean power off. when i started back up no UI again.

 

any advice?

Well I just reloaded unraid 7.0.1 onto my flash drive again and everything was working fine. transferred my config file over and reinstalled my plugins and I just got a message saying my flash drive is corrupted. So either one of my plugins is conflicting with Unraid, or I have a corrupted flash drive. Will update when I replace my flash drive and hopefully I will have a stable OS and GUI.

Another possibility is that one of the .cfg file under the config folder that you copied over was already corrupt.  These files should all be human readable text files, and a sign of corruption is them not being pure text.  Fix Common Problems plugin would typically indicate which one in such a case.

It did cross my mind that the corruption was in one of the config files I copied over. my next step was going to be going through the config files one at a time to see which one was causing this as I only copied the Dockerman files the first time I assumed it was in there.. Fix Common Problems wasn't throwing up any errors. 

 

But I rebooted and started a memtest and I may have a problem with my RAM, which would probably be the root of all these problems if that's the case. The Ram is only a few months old but I may have just got a faulty stick.

 

Will update when the hours of memtest are over.
