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 1 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]; ]

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

Thanks for any help!

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.

Where are my vm disks? :)

Thanks!
