I tried to get the mountpoint with the command from tony but the result always was "The uuid you supplied was invalid."

To get a new/live log i restarted the toolstack (the 100th time..) and now everything is working again. I dont know why but okay..

Thank you very, very much olivierlambert and tony for your help!!!!

tony Where is the Mountpoint? i can not find antyhing to the uuid

Or can i just reboot the xen server?

But how can i find and break the lock?

I searched every uuid (pbd, sr, vdi, host, ..) but cannot find anything.

Many thanks for the help!!

Unfortunately I still could not solve the problem. Is it advisable to restart the host completely?

EDIT: Found this in the xensource.log:
PBD.destroy locking failed: caught transient failure OTHER_OPERATION_IN_PROGRESS: [ SR; OpaqueRef:d4815da4-f7ca-40b0-ab21-f67411a7abf3; plug ]

I already checked all SRs and PBDs but the UUID can not be found.

Could this be the problem?

It was the false UUID....sorry! With the correct UUID it took about 3-4 hours and I ended up with this error:

xe pbd-unplug force=true uuid=44e9e1b7-5a7e-8e95-c5f1-edeebbc6863c
Another operation involving the object is currently in progress
class: SR
object: b7b541e7-a44d-61b7-0db4-55a0f9ce78bb (NAS2 ISO)
<extra>: plug

I used this UUID respectively this command "xe pbd-unplug force=true uuid=b7b541e7-a44d-61b7-0db4-55a0f9ce78bb"

With this command i get (copy-pasted the uuid)
The uuid you supplied was invalid.
type: PBD
uuid: UUID from SR

Edit: xe task-list = empty

There is one SR (ISO repos) that is shown offline but it is definitely online. I cannot repair or remove it.

If i try to remove it, xoa starts "Async.PBD.unplug" in the tasks, but after few minutes/hours the task is gone and the SR is still there.

olivierlambert Host ist still in maintenance mode...
Result of xe task-list is just blank

It was yes, but the NAS was offline.
Now XOA shows "server_init (on myserver) 0%" in tasks. Will this exit the maintenance mode?

Could it be a NAS (ISO Repository) who is offline?

They are all green

olivierlambert I wanted to move the vdi from one local repository to another, but it didnt work - now no progress or task is running.

Can i check the xapi status for what he is waiting for? And maybe kill this task?

tony The xapi.service is running. No didn't try a restart - I was afraid that no VM would start up after that, but I probably have no other choice.

I restarted the toolstack on a xcp-ng 8.0 master and now he's not able to exit maintenance mode.
If I try to start a vm it says "Cannot start here (host is disabled)" and if I try to enable it says "The host toolstack is still initializing. Please wait." - for 30 minutes.

Is there a workaround for this?

Hi,

i have two pools: One pool with five Hosts (~60 VMs) and one pool with one host (with ~30 VMs) and i want to merge these two. Is this possible? And how?

Unfortunately I could not find anything related to this.

Hi,

I've got a beginner question.
If there's a Pool with 3 xcp-ng servers (no shared storage) and the pool master goes down, what happens to the slaves?

Unfortunately I have not found anything about this.
