Re: [Xen-API] Error Introducing Metadata Volume:5

[Alejandro Flores <alejandrorflores@xxxxxxxxx>]

Hi Dave!

You're wright! The problem with this error is because the VG was full and xenserver couldn't create the MGT LV on it.

This VG has 10TB and we have created 5 disks of 2TB, so it's full. But, after we have corrected this error and introduced and pluged this SR, I can't see my VMs! It doesn't show any of my 5 disks. But, looking at the status tab of this storage it shows 10TB used.Â

Where are my vm disks? :)

Thanks!

Hi there,

I did a fresh install of my Xenserver 6.2 and I can't reattach a second local storage disk. After running all those comands ( sr-introduce, pbd-create, pbd-plug ) all went fine, but when I try a rescan from xencenter it shows this error: "Error in metadata volume operation for SR"

Here's a log snippet of the error:

"Nov Â1 19:17:49 xenserver-storage xapi: [debug|xenserver-storage|393 INET 0.0.0.0:80|sm_exec D:de8b15aee69e|dispatcher] Server_helpers.exec exception_handler: Got exception SR_BACKEND_FAILURE_181: [ ; Error in Metadata volume operation for SR. [opterr=Error introducing Metadata Volume: 5]; Â]

This error comes from the storage manager. Have a look in the SMlog -- there might be more detail in there, possibly including a backtrace which should help identify the root cause.

I think the "metadata volume" refers to the LVM LV with the name "MGT" which is used to store internal state. Is the SR is completely full or read-only?

Cheers,

Dave
