XCP-ng host not seeing storage after unmount / mount

This means a SR used in this VM can't be reach on host 2. You should boot it.

@olivierlambert this is by mistake, i used to have a host 2 also in the pool that i don't use. now i removed it by the pool.

error log: still same without the line of host 2 missing.

Do you have an ISO plugged in this VM by any chance?

Bambos

@olivierlambert no, just 2 vdi. i tried to disable the dvd-drive from boot order without any change.

I would check if you don't have a stalled NFS connection somewhere. Do you have a working df -h output on your host? Anything special on dmesg?

One way or another, XAPI still think there's no access to those shares. You can also do a xe-toolstack-restart and try again.

Bambos

@olivierlambert df -h
looks like it mounts correctly the specific NFS

dmesg nothing special, toolstack restart i did also from Xen Orchestra , i guess is executing the same command.

Do a xe vm-disk-list uuid=<VM UUID>, and then for each SR, double check the PBD is connected.

Bambos

@olivierlambert said in XCP-ng host not seeing storage after unmount / mount:

xe vm-disk-list uuid=<VM UUID>

Hello Sir, i have SSH on the host and run the command , using the uuid of the VM we are trying to start.

olivierlambert

Okay sqo both disks are on VM_space_H1. Do a xe sr-param-list uuid=<SR UUID>, get the PBDs and for each do a xe pbd-param-list uuid=<PBD UUID> and paste the result
