VM Manager won´t start - cannot add /domains

[_astro_]

Hi everybody,

 

I may have deleted the domains share somehow. It is not there anymore.

When I want to open VMS it says couldn´t start libvirt services.

If I go to settings VM Manager it say there:

/mnt/user/domains/ couldn´t find path

 

When I want to create a share with the name "domains", it won´t show up. No error msg though.

 

I had installed a Win10 VM once. I just started to use unraid. the isos are still there.

 

Is there a way to re-install the domains Folder for VMs?

 

I have no idea what to do. Fix common problem says all fine.

 

Any suggestion appriciated.

 

Thank you.

You should post your diagnostics

It is really strange. 

The diagnostics say there are 20 shares.

But I can only see 16 in the Unraid dash.

Any help?

mkdir '/mnt/user/Domains'

 

Your creating Domains, not domains, Linux is case sensitive.

That's exactly the problem:

 

Since the share 'domains' seems to be gone. I thought it may be sufficient to just create one manually.

 

When I try to create a share with the name 'domains' int the Unraid gui, I can press Apply and all seems normal but the share doesn't appear.

 

I can create one with 'Domains' though, but that won't do the trick.

 

Is there a way to reset the VM mounting domains?

Try creating the folder manually:

 

mkdir /mnt/cache/domains

I am a bit speechless. Is that normal? Kinda lost with this to be honest.

That should work, shouldn't it?

First one is a puzzler.  Second makes sense since it's missing the leading slash.  Best guess is that the array isn't started or in maintenance mode.

 

Can you post a new set of diagnostics which reflect the situation after running those commands, but before a reboot.

The diagnostics (shares folder) doesn't reflect what's actually there as a share.  It's simply a dump of all the .cfg files.  IE: You at some point HAD those extra 4 shares, but now you do not.  While I haven't gone though each of the .cfg files, there will be 4 of them that say the share does not exist on any drive.  EG: "T------------o.cfg"

here ist the diagnostic

with the reboot it created the domains share as root.

VMS is back as well, but cannot find its files.

upps. no idea how that happened. I was just adding the zip file. Should I delete the post?

I would suggest you do - nobody is going to examine the contents of that wall of files.

You need to mount the NVMe device, and check that mountpoint (or the VM path) is correct.

 

May 15 21:19:15 Tower unassigned.devices: Disk with ID 'CT1000P2SSD8_2139E5D6640F (nvme0n1)' is not set to auto mount.

 

 

P.S. this indicates that one of the cache devices dropped offline in the past:

You should run a scrub and monitor for more issues, more info below:
