Discussion:
[linux-lvm] Recovering from incomplete pvmove

A few days ago, I had, I now know, a drive failing and attempted a
pvmove.

According to what I could see, some data was recovered. However, the
source drive is now scrap metal, from what the data recovery company
tells me, so I am wondering whether I can restore anything from the new
target drive.

Can you help?


Ubuntu 14.04.1 LTS
Kernel 3.13.0-86-generic
LVM version: 2.02.98(2) ( 2012-10-15 )
Library version: 1.02.77 ( 2012-10-15 )
Driver version: 4.22.0

Anything else that I can provide?


Thanks,
Brian

how far did the pvmove get? What was the layout of the LV? Did you already attempt mounting it?

Thank you for responding, Jonathan.

The drive had a dozen partitions ( 250 GB each ), and, as I remember, I
may have successfully moved one. Shortly afterward, the drive
completely failed, and, after some attempts to restore it to working, I
sent it off to a data recovery service, who told me that the heads had
crashed, and it was scrap metal.

I have done vgscan, and that complains about missing UUIDs.

I had added a new drive and one or more PVs to the VG, and that was what
I was trying to pvmove.

I have not attached the "new" drive to the machine since the old one failed.


I suspect that things are past saving, and that the parts of the drive
that may have been successfully transferred are beyond recovery.
However, I have never worked in this part of LVM, so thought that I
would ask.
