Hi,
I've a desktop machine, running Opensuse 13.1/x86_64.
It's booted to a RAID-10 array: "/boot" is on RAID, "/" (root) etc are
on LV-on-RAID.
I'm up & functional -- I can read/write all existing
drives/volumes/partitions.
BUT ... today, I attempted to create another, new LV. It FAILs:
lvcreate -L 200G -n LV_TEST /dev/VGD
File descriptor 5 (/run/systemd/sessions/1.ref) leaked on
lvcreate invocation. Parent PID 24577: bash
Incorrect metadata area header checksum on /dev/md127 at
offset 1069547520
I also notice that none of the {pv,vg,lv}scan tools work anymore, even
though they used to,

This article
6.4. Recovering Physical Volume Metadata
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/mdatarecover.html
suggests what I *think* may be a relevant solution,
"If the volume group metadata area of a physical volume is
accidentally overwritten or otherwise destroyed, you will get an
error message indicating that the metadata area is incorrect, or
that the system was unable to find a physical volume with a
particular UUID. You may be able to recover the data the
physical volume by writing a new metadata area on the physical
volume specifying the same UUID as the lost metadata."
but I am NOT at all clear/certain that it's the right solution for this
problem.
Given the data above & below, and anything else I can provide, IS that
the right approach to fix this?
If it is, I'm hoping to get some help making sure I get this procedure
right! afaict, that procedure CAN work, but if you get it wrong, you're
hosed :-/ I understand I'm in over my head here, and appreciate any &
help I can get!
Thanks! Grant
here's more of the data from my system,
