Hi,
I'm unable to create a new LV on an existing VG with LVs.
I'm on

Is it a home-brewed kernel? Have you tried with a different one?
lvm version
LVM version: 2.02.98(2) (2012-10-15)
Library version: 1.03.01 (2011-10-15)
Driver version: 4.29.0
This looks like you might have a mismatch of device-mapper and LVM.
Where did you get that device-mapper from? I am not aware of any 1.03.01
version.
I have a VG with lots ov available space
vgs
VG #PV #LV #SN Attr VSize VFree
VG0 1 7 0 wz--n- 930.19g 855.19g
It's already got LVs on it
lvs
LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert
LV_ROOT VG0 -wi-ao--- 20.00g
LV_HOME VG0 -wi-ao--- 40.00g
LV_SWAP VG0 -wi-ao--- 2.00g
...
Time's passed. Now, when I attempt to create a new LV on the VG, if fails with
lvcreate -L 30G -n LV_TEST /dev/VG0
/dev/md1: lseek 18446744071795900416 failed: Invalid argument
18446744071795900416 - this is an interesting number, actually it is
2**64 - 1825 * 2**20. Looks like some integer overflow.
Run the command with -vvvv and attach the output, along with metadata
(/etc/lvm/backup/VG0), please.
Run the command under strace and post the output, please.
and in syslog I see
Apr 07 21:34:21 xen01 kernel: md1: unknown partition table
This looks like a MD issue. Is this some hardware raid?
The VG's on a RAID1 array.

The RAID's healthy, the system boots, and I can see/use all the existing LVs on the VG/PV.
I just can't create new LVs anymore.
Any suggestions at to problem & fix?
