Nightmare Lost all Vm's & Containers following Update Guidance !! How to Recover Please

[OsoPolar]

HI Guys Having a nightmare i waited untill version 6.12.3 rolled ouit before updating. I stopped my VM's with VM manager and my Docker Continers manually took array offline. The used O/S updater everything went fine no errors reported or seen. On reboot no VM's no Containers showing what can i do to get them back ?

According to diags both the docker and libvirt images are new, docker you can just re-create the image, for libvirt all volumes appear to be mounting, post output of:

find /mnt -name libvirt.img

 

[OsoPolar]

Think it has stopped now no further output. Please can you explain why this has occurred?
Not sure what you mean add them back i dont want to reconfigure some 25 containers again and setup my VM's
I have Home Assistant on one with years of configurations on it.
Is not possible to rollback ?

No need to reconfigure, see the link.

 

As for libvirt you have multiple images, check that date on the other ones and/or try them.

Hello i am kind of noobish re the backend of Unraid 
When you say multiple libvert images check date how do i do this ?

 

[JorgeB]

you can do 

ls -lh /path/to/libvirt.img

Then and if the date makes sense for that to be your previous image point the VM manager to that file and see if the VMs come up.

[OsoPolar]

root@Bearcave:~# ls -lh /path/to/libvirt.img
/bin/ls: cannot access '/path/to/libvirt.img': No such file or directory

 

Hi 

I had 3 VM's

The PB is a Proxmox Backup Server image

I have a Home Assistant VM  which  i use it daily

The other is Windows 11, which  i use it daily

[OsoPolar]

Does this have anything to do with the issue 

[OsoPolar]

If use restore will it put everything back to normal ?

I even ran Update Assistant which said everything was fine!

HI
I have added everything back as suggested but none of the apps open from the web gui
All of them are blank pages see image Here is a log just from one app Radarr  https://paste.centos.org/view/8d8aea0a

You are meant to replace /path/to with correct paths from results above.

HI

I have looked at these and still not 100% sure what  you mean point VM manager at them 

I should have 3 VM's

1. Home Assistant (Critical)

2. Windows 11 Pro (Important)

3. PBS Proxmox Backup Server this is the vdisk2.img  see 2 times 
But all the other libvirt images is 2 Jul  or 18 July or 19 July  but they are all the same size 
How do i find my HA VM?

[JorgeB]

Go to Settings -> VM Manager, stop the service, and make "Libvirt storage location" point to /mnt/user/PBS/system/libvirt/libvirt.img since based on the date that's the more promising one, then restart VM service and see if the VMs are back.

[OsoPolar]

OK your a star got me back my VM's but i am having config issues in the docker  apps
you said i would not have to re configure if i added them back from app previously installed 
But none work and missing config. I used a custom docker network name and i recreated it but it does no work 

the only way i can launch the apps is using host and then the config is screwed up 

is there anyway to recover config files please?

 

[JorgeB]

Restoring the apps should bring them all back as they were, assuming the same appdata is being used, you can also search for duplicate appdata folders and docker images.

[OsoPolar]

OK i am 95% back  to normal  just curious if you would know i setup a custom docker network with the identical name as before the update.
When i try to use it nothing works with it blocks the webui??
