Pengman Posted October 8, 2018 Share Posted October 8, 2018 (edited) I've had an issue with my server which caused the following problems: a) unable to write to the server via the smb network, getting the message that the drive is full even though the UI shows plenty of space (both on cache and on array) b) unable to start some of my docker apps, but some still ran c) unable to start a ubuntu server VM While messing around I seem to have fixed a) by restarting (at least it works for now). And b) by removing the docker.img file and re-adding my dockers apps. But c) still remains, the error message I get is this: Execution error internal error: qemu unexpectedly closed the monitor: 2018-10-08T19:50:58.908139Z qemu-system-x86_64: -vnc 0.0.0.0:1,websocket=5700: Failed to start VNC server: Failed to find an available port: Address already in use I tried to go into the vm settings and manually set a vnc port, but got the error that is is on a read-only filesystem. Now, that message seems to be related to the disc-full error from a), so I'm at a loss. While booting the system I noticed these messages: which seems to indicate some disc error, but I did a disc check on the cache (as described in the wiki) which didn't seem to find any errors. My hardware is - a ASRock - C2750D4I MB with 8 GB of RAM, - a 4 GB parity disc - an array of 2x4GB + 2x2GB assorted discs - a cache of a 250GB Samsung 850 EVO SSD - and the system is on a 8GB "Cruzer fit" stick I hope someone can give me some pointers, and please ask if more detail is needed. #Pengman server16-diagnostics-20181008-2145.zip Edited October 9, 2018 by Pengman Quote Link to comment
JorgeB Posted October 8, 2018 Share Posted October 8, 2018 You libvir.img also is corrupt, you need to restore from backup or recreate, can't see why you're getting disk full errors though. Quote Link to comment
Pengman Posted October 9, 2018 Author Share Posted October 9, 2018 Thanks for your answer. I do not have backup of that file (should I have?) How do I recreate it? I have restarted the system since I had the disc-error on the array, so I might have to create a new topic on that if/when it returns. Quote Link to comment

Settings -> VM Manager Stop the service and delete (all VMs will be gone, you can copy the XMLs before doing if still possible) Quote Link to comment
Pengman Posted October 9, 2018 Author Share Posted October 9, 2018 Thanks again for taking the time to help me. I have just grabbed copies of my vm xml, so I'll try that. Is the CA Appdata Backup / Restore v2 Plugin the recommended way to keep backups of important files, or is there a list somewhere of files I should include in my backups? Quote Link to comment

Pengman Posted October 9, 2018 Author Share Posted October 9, 2018 I got my VM back, so I consider this solved for now. Thanks for the help once more. Quote Link to comment
